Most of my Instant Discoveries are also inlaws that I don"t want to add to my tree. With only two options: Accept and Reject, I have to reject them so they won't get added to my tree. They really need 3 options; 1. Accept match and add to tree 2. Accept match but don't add to tree. 3. Reject match.

It is my understanding that most companies allow for about 1 mismatch every 100 or so SNPs. That is to allow for misreads and the occasional insertion, deletion and mutation. So you might want to include a column with a 100 length moving average of the number of differences to allow for these.

Group: DNA Painter: What Are the Odds? (WATO)
Here's a few of the tips I can give for WATO after my use of it: 1. Make sure you are using Version 2 and not Version 1. The probabilities have changed and are more accurate in V2 for smaller segments under 40 cM. The results between versions can be very different. 2. WATO"s probabilities come from an Ancestry paper and it works best with Ancestry data. Use the standard cM Ancestry gives you after Timber because Timber was designed to give you average cM that match the expected averages for each relationship. 3. Don't worry about endogamy with Ancestry data. Timber does an excellent job removing its effect. But it is a problem with data from other companies. 4. If you are using FTDNA data, recalculate all your matches stripping out all you segments under 7 cM. That will give good numbers comparable to Ancestry and strips out most of the effect of endogamy. There is a tool on the DNA Painter site to help you do this. 5. What WATO can't do for you is handling more than one relationship between two people.

Louis Kessler replied to his own comment.
Group: DNA Painter: What Are the Odds? (WATO)
Leah - Our current theory is that Rob and And's mother or grandmother is related to Gedalia's wife. We're now checking the shared matches on Ancestry between Hypothesis and Rob (and And), and will be comparing them to the shared matches between Hypothesis and the other testers to find testers who only share with Rob or And. Hopefully we can then build up their tree in CeCe Moore style to find the wife of Gedalia. Our situation's really messy, because Moshe has a brother Yehuda who we believe married Gedalia's wife after he died. We have testers under Yehuda who have much more matching between them than they should with Gedalia's descendants. (I won't mention that Yehuda's wife was a sister to Moshe's wife 3. Or that Yehuda's daughter married Moshe's son (from wife 1). - Oops. I mentioned it.) I suppose there is no way to include these multiple relationships in WATO.

Louis Kessler replied to Jennifer Mendelsohn's comment.
Group: Jewish DNA for Genetic Genealogy and Family Research
Jonny - That's important to know. Then does that imply that it might be better to use Ancestry shared cM with WATO than to use FTDNA shared cM?
Louis Kessler replied to Jennifer Mendelsohn's comment.
Group: Jewish DNA for Genetic Genealogy and Family Research
Jennifer - Tetiyev, which has no records yet. This is the generation before those who came over, so we mostly only have their fathers' first names from their children's headstones. We actually have 5 possible brothers / half brothers / cousins at the top, all from Tetiyev who took a surname similar to Zaslowsky. The DNA testers are 3 and 4 and 5 generations down, making them no closer than 2nd cousins, 2C1R, 3C and 4C. Some pairs between ancestors, especially between 3C and further do not match each other. I can try WATO as you suggest and put the testers in for one ancestor, and try to add the other as a brother or half and see if his testers fit. But there's are some incompatibilities in doing that. Leah and Jonny based the probabilities on Blaine's shared cM values. Those are an average of all companies. Most of our pairs are FTDNA and which will be higher cM than average. We have some that are Ancestry that will be lower cM than average. Also a third of our pairs are 100% AJ and the rest are a smaller percentage but all have some endogamy which adds on again to Blaine's numbers. This is why Lara's numbers are better for us than Blaine's except that she doesn't give company differences (purpose of my OP) Another complication. We suspect that some of the wives of the 5 may have been related (sisters or cousins) and in one case, A's first marriage may have been with B's widow. And we also have B's daughter marrying C's son and some of our testers are from that line. I don't believe WATO handles multiple ancestral lines yet. But I'll try WATO as you suggest and post what it shows and any hypothesis it may support or refute.

Steve - WATO can only help you determine where an unknown DNA tester is in your tree. It cannot determine if two ancestors of a number of DNA testers are brothers. The ancestors have not DNA tested and we do not know how much they share with all the DNA testers. Thanks for your thoughts on the amount FTDNA adds. You say that's about 60 cM on average. Our initial estimates from the pairs we have that have tested at both companies seem to indicate that Ancestry is about 25 cM lower than Lara's numbers and FTDNA is about 15 cM higher, so we come to about a 40 cM difference. Ancestry's Timber actually increases the difference, because for our data it seems to be taking out on average 55% of the cM for anyone under 90 cM. So a sharing of 80 cM without Timber averages about 35 cM with it, i.e. another 45 cM difference with FTDNA. Because we've got endogamous data, we want to compare with Lara's numbers. Thanks for pointing out Blaine's 3.0 tables. Blaine has an endogamy breakdown, and he has a company breakdown, but his company breakdown is for everyone, not just for endogamous. Blaine's company breakdown does give, e.g. for 2C1R, Ancestry at 112 cM and FTDNA at 136 cM for a difference of 24 cM. But that difference will be higher for endogamous because of the extra small segments FTDNA includes.

Adina - You are correct. This cannot be used to prove anything. But we do want to know which of the relationships is most likely, so that we can come up with plausible theories - just like the WATO tool can do.
Louis Kessler replied to Jennifer Mendelsohn's comment.
Group: Jewish DNA for Genetic Genealogy and Family Research
Jennifer - We have a number of testers descended from Person A, and a number from Person B. All testers are at FTDNA. We are trying to find out if A and B are brothers, half-brothers, or first cousins. So we can determine pairs of matches that if A and B were brothers, then we could average out the cM of the pairs that would be 2C, 2C1R and 3C and they should be close to Lara's numbers. Similarly, if A and B were half-brothers then the pairs would be H2C, H2C1R and H3C and we could compare those to Lara's numbers. But Lara's numbers are an unknown mix of FTDNA, Ancestry and other companies. So I don't know how much higher our numbers should be because ours are all FTDNA.
Louis Kessler replied to Jennifer Mendelsohn's comment.
Group: Jewish DNA for Genetic Genealogy and Family Research

Scott Wilds - The child has one allele that is the from the parent and is the same. That will have the identical contribution to making a match by chance. The other allele of the parent and child are independent of each other.
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
Blaine - It does help for the larger segments. e.g. If a 12 cM match has 10% chance of being false, then both parent and child have 10% * 10% = 1% chance of both being false, which is significantly less likely. But you're right about the smaller ones. e.g. If a 5 cM match has 90% chance of being false, then both parent and child have 90% * 90% = 81% chance of both being false, which is still very likely.
Louis Kessler commented on Genetic Affairs's post.
Group: Genetic Genealogy Tips & Techniques
I'm surprised by this table, because I would think that the probability of being IBD would be completely dependent on the number of SNPs. That's because the probability of matching by chance is computed from the average probability of heterozygous SNPs on the person and the person's match combined with the probability that one of the alleles on each SNP of one person randomly matches an allele of the other person. Since neither of those probabilities is dependent on cM, I see no reason why cM should have anything to do with it.

Louis Kessler replied to his own comment.
Jennifer - Yes you could search trees at Ancestry one by one yourself, looking manually for common ancestors. But you don't have a pre-selection of Jewish trees to do this with. Our DNA matches are mostly Jewish. And the Common Ancestors DNA filter does this automatically for us.

My question is how many total matches do you have when you apply just the Common Ancestors DNA filter. I'm guessing you'll have a small number like me (18) rather than a larger number like Blaine (431 prior to purge, 362 after).
Louis Kessler replied to his own comment.
Blaine - In your (excellent) article, you said: "I have 69 matches in the range of 6-7 cM that have a Common Ancestor designation, out of 431 total (so 16%)."

By comparison, even though I've got so many more DNA matches than you, I only have 18 matches with a Common Ancestor designation (I'm curious how many Jennifer has). This is likely because my documents in Romania and Ukraine only go back to the 1800's and I can't build my tree more than 5 generation back. That's why I see the Common Ancestor filter as very valuable.

My lowest match of those 18 is a 3C1R who shares 18 cM on 2 segments. So I have a good hint at 18 cM and nothing useful below that.

Louis Kessler replied to his own comment.
Blaine, The smaller DNA matches for both Jennifer and myself are mostly people with significant European Jewish ethnicity.

Ancestry's Common Ancestors DNA filter will only compare trees of people who are DNA matches. So all these hundreds of thousands of Jewish testers' trees are compared to ours. Through that filter, I found 3 relatives who I was able to determine my connection with, and I was able to add them to my tree and also a connections, not DNA-based connections.

I in no way will ever attempt to say that the small amounts of DNA we share prove the connection. I know that's absolute hokum. The matches may be false or come through different common ancestors than the one the Common Ancestor filter identified.

If Ancestry had a Common Ancestors filter that would compare my tree with all other Jewish trees at ancestry, then I'd say get rid of all my matches below 40 cM. But since these matches are run through that filter, they remain valuable to me, because every so often, the Common Ancestors filter will find another one.

I have 6 second cousins at Ancestry whose largest are 58, 38, 34, 25, 23 and 13. The total I share with them (in the same order) are 202, 96, 73, 162, 159, and 99. What I find most interesting about this is that Blaine's Shared cM 4.0 at dnapainter says a 2C should range from 41 to 592 cM with a mean of 229 cM. All my values are below the mean. I have 100% endogamy. What this seems to show is that Ancestry on average is over-downrating my shared DNA with their algorithms.

https://isogg.org/wiki/Identical_by_descent
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Debbie - Compare your raw data over a stretch where you match someone, and over another stretch where you don't. You'll likely see about 99 out of every 100 alleles half-match in the first case, and 95 out of 100 in the second. There is quite a distinct separation between the two, which is why matching works so well right now.

Adding extra markers to compare may increase the SNP density, which will help for smaller segments, but segment matches of 15 cM or more are already almost all IBD matches with current microarray technology and WGS can't improve on that.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Debbie - Blaine has in the past referred me to this paper that says WGS will not provide much improvement for relative matching:

Louis Kessler replied to Aaron Wells's comment.
Group: GEDmatch.com User Group
Aaron - Yes, I was thinking of changing the ones with the issues, but after using your GEDCOM search and not finding them anyways, I saw it wouldn't have helped. Your search could easily strip any parenthesis or quotes from around names and split up names containing a slash. The real problem in my case are that my forenames and surnames are translated from Romanian or Russian. And the documents I found even spell them differently, so I have to pick just one variation for the name. Someone may have the same ancestor, but chose a different spelling for the name. When I'm looking for my names in a database, I look at anything the sounds the same. Daitch Mokotoff soundex is good for this. And a first name like Joseph can not only be Joe, but has ethnic variations such as Josub, Iosub and Yosef. Also, I see you must be checking other facts to verify the name e.g. Joseph German has a few entries when I search, but they are different people so you correctly don't include them. That is a problem because birthyears from the Eastern European documents often have to be estimated from ages which are as poor as ages on our North American Census documents and often give a several year range. And if you use place names, they are also inconsistent. I've seen a hundred different ways to spell Mezhirichi. Checking only ancestors will work only if two cousins have researched to the same ancestral generation required. If one has fallen one or two generations short, a match won't be found, even if the other has the descendancy correct down those one or two generations. So there's just a few of my thoughts on why some people like me will not have any matches.
Louis Kessler replied to Aaron Wells's comment.

Louis Kessler commented on Eugene Deschaux's post.
Group: Genetic Genealogy Tips & Techniques
Eugene: Excellent work. The key result out of your analysis is that only 4 segments out of 66 = 6% don't match in the parent and are likely false matches in the child. But it gives an indication that individual segment matches are not that bad at MyHeritage. You seem to have a category IIa and IIb. The IIa is clear enough, but the IIb seems to indicate that you think you have matches to some of these 20 relatives through both parents. Why not check the other parent to see if you do. I would expect it would be a rare occurrence at the segment level. Category III are all likely valid. What is happening here is that at the end of segment the child got, they are randomly matching through both chromosomes to both chromosomes of their match, where their parent is not. So the child has a bit of random matching at one or both ends. Remember that a by chance match can be up to 15 cM, so you can have up to 15 cM of random match at either end of a real match. You say the largest extra that you have is just 2.2 cM, and that much extra in no way disproves that these are real matches passed down from the parent. Now take a look at, say 10 of the people who your nephew matches but he doesn't match either parent. Look at those matches in a chromosome browser and see what the distribution of segment lengths are. There shouldn't be any larger than 15 cM. And you'll likely find at the 8 cM threshold, indicating they may be false or that their parent's match might be below the threshold for includance. Actually, your results here (4 out of 66) are better than I would have expected from MyHeritage due to their imputation and splicing.
Louis Kessler commented on Eugene Deschaux's post.
Group: Genetic Genealogy Tips & Techniques
Here's something else you can do. Find someone on your nephew's father's side that your nephew also matches. Then go to your chromosome browser and include all 3 of them. See how many individual segments your nephew matches that his father doesn't. Do this for about 10 people on his father's side and 10 on his mother's side. That will give you an idea of how good MyHeritage's individual segment matching is. I'm assuming that you/your nephew are not from an endogamous population. If you are then you could have people you match through both parents, but neither parent alone has enough to match. But you are correct. You cannot ever assume that people who don't match one parent, must match through the other. A false match is always a possibility. In your case, with one parent tested, you can use shared matches and/or MyHeritage's clustering algorithm to find groups of matches who don't match the parent tested.

This got me wondering if the smaller matches are good hints for me, in an endogamous population.

Ancestry classifies me as 100% European Jewish. I can compare my ethnicity with each of my matches and they tell me what % European Jewish my match is. I did this for my closest 20 matches, and my first 20 matches at 40 cM, at 20 cM, 15 cM, 10 cM, 9 cM, 8 cM, 7 cM and 6 cM. I marked down what percentage of European Jewish they had. Then I sorted each group of 20 highest to lowest. I get the table below.

Of the 180 matches I checked 179 had some European Jewish Ancestry. Over half of the matches also had 100% European Jewish ethnicity and many of them have 50% or more.

There is a much greater chance that I might find a connection to someone with European Jewish ancestry than someone without any, so these are good hints. Using ancestral surname and place filtering tools, I might find that some of these people are relatives and they can help me extend my family tree.

Does that mean that we share DNA? Not necessarily. The matches, especially the small ones, may be false matches.,

Or we may actually share DNA. but the segments we share may not be coming from the common ancestor we found, but may be from another more distant line that we’ll never find, or it may be (especially in my case) general background noise from distant ancestors due to endogamy. We don’t know and cannot tell.

None-the-less, these matches are hints that might connect you to a relative.

Rosemary - There is nothing wrong with researching one of your DNA matches and through documentary records, finding out that they are related to you and making connections to them. That, after all, is why we as genealogists DNA test in the first place. We are trying to find new cousins that we can connect our tree to who may give us added information about our own ancestors.

What is wrong and what is confirmation bias is then assuming that the small DNA match was IBD and was passed down to both of you from the common ancestor that you found.

The small match could very well have been passed down to you from a completely different common ancestor. Or it might have been a false match (not IBD at all), and you actually don't share any DNA at all with that person.

As long that DNA small match assumption is not made, with the claim that the DNA match proves your connection through that common ancestor, then you're fine.

Thinking logically, the cover is only for marketing because it never gets looked at. The 12 months each get to to be viewed each for a month. So you need the cutest, most adorable and irresistible picture you can find to make your calendar a must-have. I think you've got some better ones, like a mama and a baby. And if the cover is that good, then it might prompt leaving the cover page up on the wall for a few months into the next year. If this calendar is only Boomer, then the cover has to have him doing something cute, or with another koala.

Louis Kessler replied to Paddy Waldron's comment.
Paddy, thanks for explaining. Your cM table has the same ranges on each line as the Mb table where 0.8 Mb = 1 cM. Okay. That's fine then.

But I still don't think generally the distant ancestors will move down the list and the recent ones will move up. I think it will be exactly random as to which move up or down.

Take any size segment, e.g:
8 Mb on average = 10 cM
One extreme: 8 Mb = 100 cM
The other extreme: 8 Mb = 1 cM

So with one extreme the segment will move up your list, and the other down your list. But on average, each segment will stay in the same place.
Louis Kessler commented on Alona Tester's post.
Here's looking at you, kid.
Louis Kessler replied to Paddy Waldron's comment.
Paddy, Sorry, I don't get the reasoning behind your statement "distant ancestors will generally appear shorter on the centiMorgan scale than on the megabase scale; segments which descend from more recent ancestors will generally appear longer on the centiMorgan scale than on the megabase scale."

To me, distant ancestors generally have shorter matches. Closer ancestors have longer matches. Whether cM or Mb is longer and shorter just depends on where the segment is on the genome.

And it would make for easier comparison if the ranges in your cM and Mb tables are the same.

Blaine - Yes, but I can imagine that the average person without endogamy might have a shape more like Shelley's, with fewer larger matches, and many more false smaller matches. What we could be seeing here is the effect of Ancestry's Timber algorithm on endogamy. If they didn't trim my matches and my distribution had the same shape as Shelley's, I might have hundreds of thousands of matches in my smaller groups.

Louis Kessler replied to his own comment.
Blaine - I'm just math-ing it Blaine. I believe most small segments under 7 cM will be 10 to 25 generations old. I don't believe that most of them will be over 20 generations old and I really don't believe that a 10 cM segment will be 32 to 52 generations old.

Genealogically, it doesn't make a difference to me either way, since my Romanian and Ukrainian roots only allow me to research 5 generations max, and I can't bias my maths down that far.
Louis Kessler replied to his own comment.
Debbie - Yes, which is exactly why I can't believe there isn't a shorter path of a 10 cM segment to the common ancestor than 32 to 52 generations!!!

(See my reply to your comment below for more discussion on this)
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Debbie - I have read Ralph and Coop many times. But I've never been able to reconcile their statement you quote above that the average age of a 10 cM shared segment is between 32 and 52 generations.

The probability of a 10 cM segment recombining in 1 generation is: 9.05%. The probability that it recombines in 20 generations is (1-0.0905)^20 = 85%. The distribution has a mean of 10.5 generations.

If it recombines, then that 10 cM segment no longer exists. It has died. It is a dead segment (like a dead parrot). It can no longer match anyone with that same 10 cM segment.

So R&C are saying that a 10 cM segment survives 32 to 52 generations down one descendant line and the same down a second descendant line to be the AVERAGE number of generations needed to match.

I just find that to be an unbelievably high number of generations and I can't stop from thinking that there has to be a closer MRCA for that 10 cM segment along some other ancestral path.
Louis Kessler replied to his own comment.
Paddy - Yes exactly. It is the specific ancestral path that we are dealing with. And the simple math of recombination (i.e. a 10 cM segment will recombine almost 10% of the time) states that the majority of segments will be under 20 years old.

Louis Kessler replied to Debbie Cruwys Kennett's comment.
Speed and Balding's paper does say they are using the Decode Genetic Map which specifies male and female recombination rates over 2,667 Mb across the 22 autosomes. So even though they are giving results in megabase pairs, they are using correct recombination rates over each Mb for the simulation.

Since 1 Mb is approximately 1 cM, if you use the cM value as a lookup, it should give a reasonable estimate, e.g., you may have a 5 cM segment which is only 1 Mb long, but as long as you lookup 5 Mb in their table and not 1 Mb, you should be okay.
Louis Kessler replied to his own comment.

I should mention that both Debbie Kennett and Andrew Millard disagree with my analysis and conclusions and we have agreed to disagree.

Even so, I still agree with Blaine that small segments are "poison" because (1) they are often not IBD matches, and (2) they still can be 10 or more generations back. Once you get that far back, it could come from any ancestral path, not just the one you are theorizing. The only way to verify is a Jim-Bartlett-like tracing the triangulation group back generation by generation using DNA matches at each cousin level all the way back.

Sorry Ashley, I don't mean to come off strong. But really, if you are using your 6 cM and 7 cM matches (or even up to 20 cM) to try to find connections on your family tree, it will be long and mostly unrewarding task for you. Here's my alternative suggestion, that can do the same task and will likely have a much higher success ratio. Go to your Ancestry Tree. Get your list of all people in your tree. Go to Ancestry -> Search -> Public Member Trees. Enter each person in your tree, one by one, into this search and find all the Ancestry Member trees that contain your relatives. This is much better than trying to use small DNA matches to find possible relatives who might have trees that connect to yours.

Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
To be honest I always thought Ancestry's low limit of 6 cM was ridiculously low. 15 or 20 cM is more reasonable for the general population. For those with endogamy like me, there's about 40 cM of background noise added to each of my matches so I don't usually look at anyone under 50 cM.

Group: Genetic Genealogy Tips & Techniques
I don't think the testing companies will ever change to full WGS. But once WGS can phase (maybe in 5 years) and that technology comes down to consumer affordable prices (maybe 5 more years), then what they could do is take the 700,000 SNPs they have now, and replace them with the phased values from the WGS. This will make matching an order of magnitude better, probably making segments down to 7 cM valid matches. 700,000 of the most variant SNPs are perfectly fine for relative matching. No need to use the whole genome. Unfortunately, I'm a bit pessimistic that the testing companies will never do this, simply because 10 years from now, just about everyone who has DNA tested for genealogical purposes already will have, and the companies won't have a monetary incentive to update their technology. It would likely take an innovative startup, something like a GEDmatch or Borland Genetics to create that phased matching database for us.
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
It's still got a ways to go. It won't make a difference for relative matching until WGS can fully phase the whole genome for us. That will require accurate and very long reads that can span every two heterozygous alleles. PacBio is getting there with their new HiFi WGS, but the reads still need to be even longer while remaining accurate. And two days ago, the announcement of the first time a full human chromosome (Telomere-to-Telomere) was sequenced that included the very difficult centromere. However, they still had to manually resolve several gaps in the sequence, so they aren't quite there yet. https://phys.org/news/2020-07-scientists-human-chromosome.html

That likely can be done efficiently as well because any segment would be either paternal and/or maternal, or it would be unknown possibly with some opposite of unknown.

Ashley Bens - You're picking a needle that could have come from 1000 different haystacks and assuming it is from the one you want it to be from. The only way to "prove" an autosomal match is from a certain ancestor is to use Jim Bartlett 's "walk it back" technique, where you need a cousin at every generational level matching on the segment to show the parent it comes from at that generation. And a Y-DNA match in no way is any proof that the autosomal segment match is from that ancestor.

Louis Kessler replied to Tim Shaw's comment.
Group: Genetic Genealogy Tips & Techniques
Tim Shaw - Unfortunately, WGS tests today are far from perfect. Short reads cannot span repeats so they don't assemble or align well and can't be relied on to correctly produce the novel variants needed for the polymorphism comparisons you're talking about. Whereas long reads today are too error filled, like up to 10%. And although they are long enough to span repeats, the algorithms to correct the errors and align or assemble them will never be able to be made to produce results good enough for Genetic genealogy. 6% of my long read aligned SNPs were wrong when comparing them to my microarray and short read results. So doing a WGS test and saving it is not a good recommendation with what's out there today. We need to wait for a better WGS test such as PacBio's HiFi test, which has accurate long reads. That technology is only a year old and analysts are still developing the assembly algorithms that will take advantage of it. Until the HiFi test or some other innovation like it becomes commercially available, I wouldn't recommend WGS today, because today's tests will never be better than the microarray tests we already have for genealogy.

I am far from an expert on WSL, just dabbling so far with Ubuntu in WSL1 to use some genetics tools. But what I heard at Microsoft Build last month was that WSL2 is fantastic. It has full access to the Windows OS and filesystem and multiple, even different versions of Linux, can be run at once. For genomics applications, the performance improvements are the best reason to switch to using WSL2.

Robin P Meyer - One page request from a tool is exactly the same as one page request a person would make. Ancestry's servers have a certain capacity, guessing 1000 page requests a second. Once they reach the capacity, the requests will slow down and start to fail. So 1000 requests per second can handle 10,000 people doing 1 request every 10 seconds. But it can only handle 10 bots doing 100 requests a second. Slowing a bot down to 1 request every 10 seconds means it would take over 24 hours to do 10,000 requests. So it's feasible for some types of analysis.
Louis Kessler replied to his own comment.
Group: DNA Software Programming
Evert-Jan - I think Ancestry might be having server load problems just from their tens of millions of subscribers. They likely started contemplating additional capacity which is expensive. Load shedding is a cheaper way to accomplish the same thing, but hurts users who use the extra services. It"s a trade off that Ancestry thought about and finally decided to do. They may be waiting until all bots are halted to then see what the server load is down to, and then will reevaluate if they still need additional capacity.

Group: DNA Software Programming
My thinking is that the automated tools of the various companies were starting to put a significant load on Ancestry's servers. The past few months, Ancestry's subscribing users have been faced with poor response times and many request failures. I don't think Ancestry would have done anything if this hadn't been the case. They had been silently allowing all the bots for years. Don't think they didn't know about them. Unfortunately and ironically, it's the success of the bots that proved their own undoing. Each one can make requests thousands of times faster than a user at his keyboard. Okay, hundreds then, if you guys are throttling. And your success with thousands of users leads to hundreds of thousands of requests, likely swamping their servers. They can tell from their logs that they know it's you. And they've taken the logical action unfortunately. They wanted a quick solution so they used their terms of service along with cease and desist with their real goal to just get all those bots to stop. It wasn't about privacy nor copying data. It was all server load. At least that's my analysis.

Group: Dante Labs and Nebula Genomics Customers
Randy - yes they do "polishing" (using short reads to "correct" long reads) sometimes several times in both alignment and assembly. But I'm worried that the polishing could "correct" some long values to be incorrect, simply when the short reads get aligned incorrectly, which to me is very possible in de novo assembly. I haven't seen any papers evaluating the correctness of polishing. Polishing sounds like something you'd like to do until you really think about it.

For security reasons, I have manually in Family Tree Builder set all of my living people private, so that they only show up as "Unknown" in MyHeritage, i.e. no surnames.

Yes. I understand. But there are nuances. e.g. You said: "then the same length Phoenix segment has to be from his mother that he shares with you ie your grandmother." Yes, that segment will be my uncle's from my grandmother. But it need not be a single segment in my grandmother. Part of it may be from my grandmother's father and part from my grandmother's mother if there was a recombination there when passed to my uncle. If so, then part of that segment in my uncle will match some people on his father's side and the other part will match some people on his mother's side. Painting my uncle's chromosomes is needed to determine the assignments of these Dark Side segments. Most of my segment matches with known relatives which gave me the information to paint my own chromosomes was at 23andMe. My uncle was tested at Family Tree DNA. 23andMe doesn't accept uploads so I don't have that information to paint his chromosomes. So for the time being, I can't make use of the reverse Dark Size information.

Jason: First, thank you very much for very being patient with me with your explanation. I am trying to work through what you mean and see your point. But to me the problem is that the result of Darkside with my uncle will give segments that may be his father and may be his mother. So it can't be used to create a kit for either his father or his mother. e.g. All Chr 1 my uncle and I match. Say that Chr came from his father. Then his Darkside is his mother. All Chr 2 my uncle and I match, but that Chr came from his mother. His Darkside for Chr 2 is his father. The Darkside output would be a combination of his father and his mother. The reason why it doesn't work in reverse for Darkside is because I share DNA with both my uncle's parents. But Darkside works for me because my uncle doesn't share DNA with both my parents and I can use it to determine my mother. But then I'm sure you know this and were trying to explain it to me because in your original comment, you said: "you would still need to determine if the segments were his mother or his father". So it's not usable in the Borland Genetics system because it doesn't represent a specific person yet.

Do you see what I'm thinking, Kevin? Borland Genetics should also segment matches with on each grandparent's side for every person with raw data. This could really enhance BG's analysis possibilities. For example, I only have raw data for myself and my uncle. So off the bat I can create a bit of my father and my mother. But if I add my uncle's paternal and maternal segment matches, and compare with my grandparental segment matches, well then now I can assign and extract grandparents from my and my uncle's raw DNA.

Kyle - I'm not familiar with Clinvar, but my direct analysis of my filtered VCF and my raw (unfiltered) gVCF files indicated that 0.08% of my filtered VCF variants were wrong and 0.13% of my raw gVCF values were wrong. That's not too bad, but the problem is that my filtered VCF excluded 0.76% of true variants. That is a rather high value, meaning the filtered VCF is missing a lot of variants. I think it's very dangerous to miss an important variant you might have. The raw VCF only excluded 0.09% of true variants, but that's the tradeoff: Lower Type I errors means higher Type II errors. The more aggressively you filter, the fewer incorrect variants you'll have, but you'll also filter out many true variants. https://www.beholdgenealogy.com/blog/?p=3021

So I'm unsure what makes you think they produce "an enormous amount of erroneous data". No-calls are not errors. My Ancestry DNA data does not include InDels. For the SNPs that chips give you values for, the data is very good. WGS can't and doesn't do any better as far as those SNPs are concerned. What WGS does is give you good values for the 6 million SNPs you have that chip tests don't give you. Have you ever compared two WGS tests done on one person? The amount of differences are astounding and will make you question how good WGS is.

Group: Dante Labs and Nebula Genomics Customers
Kyle: Interesting article. I like your point of view and some of the comparisons you've made that I haven't seen elsewhere. I have a few comments which are meant as constructive criticisms so I hope you take them that way: 1. In all cases, you call all the chip tests "Not as good as Whole Genome Sequencing". You don't explain what your "good" is. I would call "good" to be accurate SNPs for the variants you're looking for and not having inaccurate SNPs at those positions. I would not necessarily say WGS is better at that because there are many mistakes in reads and alignments and the rest of the analysis that gives you your WGS results. 2. Chip tests give you way more than 0.02% of your variants. It is estimated that there are about 30 million SNPs in all people and one person may have 6 million, with any two people averaging 3 million SNPs different from each other. A chip test will likely give you 300,000 of your 6 million variants, or about 5%. 3. You mention insertion/deletion variants like BRCA are often not correctly called by chip tests and you link to an article about that. The other side of the story you don't mention is that 23andMe's BRCA analysis has helped people, such as genealogist Lara Diamond. https://thelayersprojectmagazine.com/stumbled-upon-brca-results-saved-life/ 4. 23andMe is the only company that includes InDels in their raw data file. Yes, their accuracy may be low, but as long as that is realized, it's still better to have that data to analyze than not to have it. Getting InDel data from WGS results is not easy nor fun. I question how good the WGS alignment procedures are at aligning around InDels accurately and I ask the same question re 23andMe's chip test as to how they can determine an InDel is at that position. I expect once de novo assembly becomes more available, we'll get a better handle on our InDels. 5. I do not like your mentioning of imputation as an easy way to get some extra SNPs. Imputation uses population averages to assume what your SNPs are. Making that assumption for important health SNPs can result in horrible mistakes. I'd like to see an article that assesses the ratio of false positives and true negatives in the imputation of health-related SNPs. I would bet the accuracy could be well under 50% for rare variants, something that no-one would want to rely on. The 99% accuracy of actual readings is much more assuring. 6. Through the article, you talk about miscalls and even "bad call". Most chip companies replace SNP results they are cannot determine with a no-call (i.e. something like a double dash). There could be as many as 3% no-calls. More than that and the company will likely want to resample you. But mistakes on what the chip companies assign values to are quite rare. Comparing my 5 tests and ignoring no-calls, I found only 665 of the 1.4 million different positions had differing values, or 0.05%. https://www.beholdgenealogy.com/blog/?p=2700. I don't think WGS tests are as good as that. Louis

Thanks for the very informative explanation. When you say "strand", are you actually meaning one of a chromosome pair which is a "chromatid"? One chromatid comes from the father and one from the mother. Isn't it the chromatids that we want to phase? Whereas each chromatid is made up of two strands: forward and reverse where each position is either AT or CG. Also, I don't think full phasing is possible yet for the human genome. The long read segments are still not long enough to connect over all the regions where the two chromatids have the same value.

Nebula's FAQ says they do 150 bp paired-end read sequencing using high-throughput MGI DNBSEQ-T7 DNA sequencing machines. They align to hg38 using a GATK-based pipeline. Dante switched to Illumina NovaSeq 6000 systems when they opened their new sequencing centre in Italy last year. The machines are probably quite comparable. I would expect short read tests from the two companies would give similar results. There likely would be more variation from the quality of the sample than from the difference in the machines. The analysis pipelines could make a difference as well. I don't know what Dante currently uses for its short read pipeline.

Group: Dante Labs and Nebula Genomics Customers
Marko: b): No one test will give totally accurate results. And yes, some tests and some reference genomes will give more accuracy than others, as well alignment algorithms, de novo assembly algorithms. My goal is not to try to find the best of these, because there likely isn't anything that is best at everything. I've taken a few WGS tests (with one more and a de novo assembly coming) and by comparing them and various analyses of them to each other and to my 5 microarray tests, I next will be using them to correct each other and estimate error rates of the tests and the algorithms. I have enough variety already to do this now. If I was someone with just one WGS test, then yes, I'd likely want from hg19 to hs37d5. But that's not my goal here. I do have one build 38 BAM which I would think is again better than hs37d5. With all that said, you make the hg19 versus hs37d5 comparison sound interesting.

The problem is definitely something in the version of the mpileup code that Marko used preventing Long Reads from working. Using the -B option fixes it. Using the latest version of htslib might fix it as well and if it does, that's the better solution.

I think you got it, Randy. Using this post: https://github.com/samtools/samtools/issues/778 - I took their suggestion of including the -B option, and I was able to run WGS Extract successfully on my Dante Long Reads file. But that post also says that using the latest version of htslib as you mention also fixes the problem. That would be a better solution since we don't want to not do that quality check. I've now run my Short Reads test both with and without the -B option and I'll be doing a comparison.
Louis Kessler replied to his own comment.
Group: Dante Labs and Nebula Genomics Customers
Based on my observation that the Long Reads files weren't being built, I searched the web for some reason why mpileup might not be working with Nanopore WGS. I found this article and based on it, I tried adding the -B option to mpileup. It seems to be working now. I'll report back once I've tested it with my 2 Long Reads and 1 Short Reads file. Hopefully this is the fix because it's a simple one if it is. https://github.com/samtools/samtools/issues/778
Louis Kessler commented on his own post.
Group: Dante Labs and Nebula Genomics Customers
I have discovered the "temp" directory in WGS Extract is where the intermediate results are stored while the program executes. As mpileup runs, a file called temp_austosomes_raw_vcf.gz is built up. For my Short Reads file, after about 3 minutes, that file got to 3092 KB in size. I stopped the run and decompressed the file, and it had 69,927 lines in it that had extracts up to chr 1, position 92,101,761. For either of my two Long Reads file, after about 15 minutes, that gz file was still at 0 KB. There was nothing in it. My suspicion is that the mpileup program does not work on Long Reads files. :-(

Hi Thomas. Yes, that was the BWA run that I did myself. (Took 5 days). You did a minimap2 run for me at YSEQ three months ago, and I was next going to run WGS Extract against it.

David: When you run Person A versus Person B, all results are in a single spreadsheet file that contains all chromosomes on one page, and the people information on a second page. When you run Person A versus all the people in Folder B and select "Combine all results", then DMT produces 23 files, one for each chromosome and also a separate people file. It does this because you may be combining dozens of A versus B matches together and that can result in too large a file if it were put together. DMT has always done that. You just are obviously now running Person A vs Person B whereas previously you did a Combine All Results run. The coloring has changed starting in Version 3 since DMT is now set up to determine your ancestral line on each segment. You can get DMT to do this by entering the MRCAs (Most Recent Common Ancestors) for the DNA relatives that you know into the People file. The only color you'll have is purple if you haven't entered any MRCAs. I highly recommend you read the complete DMT help file. It explains everything that I've been telling you here and more. Just press the Help button in the middle of the DMT window.

You don't have to manually do that. The person you enter in File A is the person whose genome and matches you want analyzed. Usually that will be yourself. If you use your cousin as Person A, then you'll be analyzing your cousin's genome, not yours.

Thanks Katherine. I followed your suggestion and contacted AncestryDNA via their support about why I had ThruLines and then they vanished about 4 to 5 months ago. It turns out that "potentially due to a recent update", some of my relationships with my parents and grandparents are "Unknown" rather than "Biological". Once I changed them back to Biological, all my ThruLines that I had before immediately reappeared. So now I'm as happy as a clam. I suggested they add this information into their ThruLines help so that others will be aware that you must have Biological relationships for the ThruLines to work.

Blaine - What is that paper you often referred to saying that WGS will only give 10% improvement in matching? WGS results have significant error rates in reading. Alignment isn't perfect. Even the human genome reference is variable. It would be desireable if it could be done, but it would be far from easy to do it.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: Genetic Genealogy Tips & Techniques
Debbie - Yes. Using a variant to identify a match would be desireable. But that means it would also identify mismatches. Your cousins who were not passed that variant would not then appear as matches as they should. And if you had a mutation, insertion or deletion that your father did not, then your variant would be seen as a difference breaking your match with your father and all your paternal relatives on that segment. You also technically don't know which parent's chromosome that variant is on, so allowing individual variants to break matches will really hurt matching.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: Genetic Genealogy Tips & Techniques
Debbie - Yes. The average person has 3 million variants from among those 45 million SNPs. So comparing two people, they may have close to 6 million differences. Many of those are rare SNPs occurring in one in a hundred or one in a thousand people. It takes many thousands of people to identify the 45 million SNPs that may differ among us humans.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: Genetic Genealogy Tips & Techniques
David, Debbie. Well, the book analogy is not quite correct. On average, we each have about 3 million SNPs that are different from the human reference genome. Up to 700,000 of them are already tested via an array test. That means about 2.5 million variants are left in 3 billion base pairs, or about 1 in a thousand. Yes, looking at the first letter of a paragraph is a good analogy, except that all the letters in the remainder of the paragraph are identical with someone else except in 2 out of a thousand positions. Testing companies usually allow for 1 difference every hundred or two hundred SNPs because reading isn't perfect and there is the occasional variant, insertion or deletion. Therefore 1 in 500 appears as noise in matching and WGS will provide little help for matching over traditional array tests. Blaine has referred a number of times to a paper that concludes that WGS may only provide a 10% improvement in matching over array tests. So all the extra effort required to use WGS for matching really is not worth it.

Blaine and Debbie: Unfortunately the population geneticists aren't the ones advancing genetic genealogy, and the genealogists that have been for the past 10 years like Jim Bartlett and Tim Janzen aren't scientists who write formal papers that get reviewed by population geneticists. Phasing has always been known to be an effective way to filter out many of the false segments. But creating and verifying triangulation groups is just as effective because it is essentially the same as phasing. The relationship between triangulation and phasing is so simple to logic through. If you have a common ancestor who passed an IBD segment to both you and a known cousin of yours, then that segment came to you through one of your parents, most always the parent you expect. That match is now phased because both you and your cousin have different SNPs on your other parents' chromosome on that segment. Everyone in the triangulation group that matches both of you and each other must be matching on that segment of your parent and that common ancestor, other than very small segments under 6 cM that may have both parents randomly matching the one.
Louis Kessler commented on Jim Bartlett's post.
Group: Genetic Genealogy Tips & Techniques
Jim is simply saying that while many small segments from 6 cM to 15 cM are false, some are valid and are IBD and not necessarily outside the genealogical time frame. Jim basically doesn't want to throw the baby out with the bathwater. Jim's techniques include triangulation and forming triangulation groups. Most people don't realize that by confirming triangulation of all members (4 or more) of a triangulation group, you are effectively phasing all the matches in the group to one parent. Almost all matches in Jim's groups will match one or the other of his parents. And that's whether he had his parents tested or not. Almost all will pass the parental filtering test. That also means that a lot of non-IBD matches have been eliminated from the 6 cM to 15 cM matches that Jim is analyzing, including all those that would be eliminated through phasing and/or parental filtering. In other words, creating and verifying triangulation groups with segments of 6 cM or more is as good as phasing and is equivalent to phasing.
Louis Kessler commented on Ritchie Hansen's post.
Group: The Visual Phasing Working Group
There might be a sneaky thing you can do (but I haven't fully explored because I can't use VP for myself). Download segment match files for each of the siblings. Compare the segments each share with a third person. If one of the siblings matches the same people only up to a certain address, and the other sibling continues on, then that address is a crossover for the first sibling. If the two siblings match each other on both sides of the crossover, then it indicates that they fully match each other before the crossover and half match after it.

Okay, well look at this. At GEDmatch, I don't have enough matches over 90 cM to use their clustering at that level. But my uncle (also 100% Ashkenazi) does. At GEDmatch, I think they get more baseload matching than Ancestry does, maybe up to the 90 cM or 100 cM level that you mentioned previously. So here is my uncle's clusters at GEDmatch using 90 cM to 500 cM.

Jonathan, Adina: This is my theory: My parents are not related. According to GEDmatch's test for that, I'm only homozygous over a single small 7 cM segment. My uncle's parents (i.e. my paternal grandparents) are also not related. My uncle has no homozygous segments over 7 cM. I think this might be the main reason why I can separate out grandparents through the Leeds Method or other techniques despite my endogamy. I do Leeds down to my 50 cM DNA relatives and that works well and below that it starts to mumbo jumbo, so that's why my theory (at least in my case) is that my endogamy includes up to 50 cM of baseloaded matching to each of the people I match to.

Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
Celia - That's a very interesting line of thinking to come up with a solution. Hmmm. The Wikipedia formula isn't sourced either, and I don't like that it approaches 50% as cM goes out to infinity. So Wikipedia could be wrong here with respect to what we are talking about. I think the correct analysis is this: Assuming a Poisson distribution for crossovers (which is what is usually assumed), then the Prob(zero crossovers) when the mean is cM/100 is: exp(-cM/100), therefore: The probability of one or more crossovers = 1 - exp(-cM/100) For 100 cM, Poisson gives 63.2% compared to your 63.4%. Putting all the equations in a spreadsheet and comparing them, I see that your equation and the Poisson are so close that the graph only shows one line for the two. You can start to see a tiny bit in the expanded detail. I think the Poisson version I give is technically correct. But your equation does just fine as well.
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
Celia - I thought the correct equation is Prob(recombination) = (1 - exp(-2*cM/100)) / 2 as given on the Wikipedia page for Centimorgan. For 30 cM, that gives 22.6%. I've never seen the equation you give before. Can you give me a reference for that? Most people don't realize there is a mathematical difference and that cM actually are the average number of recombinations expected in one generation over a segment. For small values, the cM/100 is a reasonable approximation. Using 22.6% or 26.0% instead of 30% does not change any of my arguments above.

In general, I find FTDNA has about 50 cM of background noise for each of my matches. So for a rough estimate, I simply subtract 50 and consider that. But there's still stuff we can do. The In Common With and Not In Common With are useful for clustering and works for endogamy, because the dominant grandparent still tends to define our relatives' clusters. And we can download our segment match files and find triangulation groups to further group people. It's true that not everyone has trees, but a lot enter their ancestral surnames and places and that is very helpful. If our Eastern European records went back further than 5 generations and our ancestors adopted surnames earlier than 5 generations ago, then we would be able to connect to a few people. But the majority of our matches are obviously 5th cousins or further and as a result mostly un-connectable.

Louis Kessler replied to his own comment.
Paddy - Good. Checking triangulation is the first step. That still doesn't mean they come from the same ancestor.

One possibility is that A's father's chromosome matches B's father. A's mother matches C's mother and B's mother matches C's father. That's still a triangulation but there are three different ancestors. To prevent that case, you need at least one more match in the triangulation group and a check that every two of the four match each other.

The other possibility in small segment matches is that one of the people randomly matches with both parents' chromosomes the one chromosome match of the other two (or even all the other people in the triangulation group). This case is a horrible one because just about all tests will seem to indicate they match.

All I'm saying is not to conclude that very unexpected small triangulations indicate one common ancestor. If that was happening at 15 cM or even 12 cM, then I'd say it's likely true, but not at under 8 cM.

You're the first Alona I've ever met. So now you made me curious to look your name up. I'm surprised to see (via Wikipedia) that Alona is a Hebrew name, still popular in Israel:

Alona Barkat (born 1969), Israeli businesswoman and football team owner
Alona Frankel (born 1937), Polish-Israeli author and illustrator of children's books
Alona Kimhi (born 1966), Israeli author and actress
Alona Koshevatskiy (born 1997), Israeli rhythmic gymnast
Alona Tal (born 1983), Israeli television actress

Alona is the feminine version of the Hebrew name Alon which means "tree" or "oak tree" in the Hebrew language. In Israel, Alon is used both as a surname and as a masculine given name.

Who were you named after? Why did your parents name you Alona?

Thank you for telling us this Blaine. I hadn't considered YSEQ for any of my WGS analysis before. I see they have both FASTQ Mapping to both hg38 and to hg19. You chose hg38 which is what YSEQ uses and what FTDNA uses for its Big-Y 700. And hg38 is definitely wanted for health analysis. But as you know, all atDNA matching for genealogical purposes is compared via hg19. And YSEQ's FASTQ Mapping to hg19 says for that they will also "create a file format that can be used for consumer genetic online services like GEDmatch" which they don't do with the mapping to hg38. I'm intrigued to see what they produce for that. So I'll likely try the mapping to hg19.

Blaine, I thought MyHeritage was sufficiently hiding my living people from others. Then a few months ago, I received an email from a third cousin (also a genealogist) who asked me to remove his birthday from my site. It turns out a smart match made this available to him. I then went to Family Tree Builder and marked each living person as "Private" and resynced my tree. My underlying reason is that my wife and daughters are not into genealogy and don't want me to include their personal information online. I try to respect that and feel that it is right to extend that respect to everybody. And to top it off, MyHeritage specifically tells you that you cannot put up information about living people without their permission. Since I have no permission from anyone, I feel it is right to respect that rule.

I've recently come to my own personal conclusion that it's important to hide all information about living people.

Kalani - I don't know. Maybe your parents are 4th or 5th cousins in some way you don't know of. Or maybe those are by chance matches since they're all less than 15 cM. Do those regions triangulate with people who form two groups that don't triangulate with each other? Or does everyone triangulate with each other? That will tell you if it's a false match between your parental chromosomes, or if they are actually the same segment from both parents.

From what I understand, even long reads are not long enough to completely phase, and that's why you can't find software to do it. There are very long sections that can be hundreds of thousands of base pairs where both parents' chromosomes have the same value and long reads can't span that. The best you can be expected to get with long reads is about 200 contigs over the 23 chromosomes.

Louis Kessler replied to Mika Sarlin's comment.
Group: MyHeritage Users Group
Mika - Something from your private FTB profiles are being put online when you sync, or there wouldn't be "Unknown" boxes put up there. What other data is being uploaded with that, I don't know. The logically correct way that "private" people should be handled is that when you mark a person as "private" in FTB, the person online should be completely deleted, and data will never sync up to MyHeritage for them, until the point you take off the "private". Living is something in-between. But they didn't take living quite far enough to protect the living the way MyHeritage's rules state. Almost all MyHeritage users are adding their living relatives to their online trees. I doubt if any of them are asking permission of each of their relatives first. MyHeritage obviously doesn't want people to take off all their living people from their trees, mark them private or mark their whole trees private. So MyHeritage needs to honour what "living" means and not make living people's surnames or data through Smart Matches available to others.
Louis Kessler replied to Marie Payne's comment.
Group: MyHeritage Users Group
Marie - You are correct. If I had to choose, I'd change living people online so you don't see surnames and their details aren't shown to others in Smart Matches. If MyHeritage did just those two things, then I'd be happy that the living people are sufficiently privatized, and then I'd have no problem taking off the "private" from all my living people. What I don't want to happen ever again (which started me on this) is to get an email from a 3rd cousin stating that I had his full birthdate on my site and that I must take it off. So my only solution for the time being is to use the "private" on my living people.

Group: MyHeritage Users Group
Thanks Marianne. Well I did a test. I created a test daughter, husband and granddaughter with FTB and marked them all private. Then I synced. They were put up on MyHeritage and were all marked as Unknown. See the 3 people in the red circle in my screenshot. I don't mind that, in fact I like that. So there is still some syncing going on with private people. Now as a further test, online at MyHeritage, I went into that online daughter I added and I edited her name calling her Online Person and gave her a birth year 2001 and death year 2015. That information now shows online as in my screenshot. Now I went back to FTB and synced. The name Online Person and the birth year and death year all got synced and downloaded to FTB. So the data for private people are syncing down for sure and maybe up as well. Again, I do like that. I think that is the correct thing to do. I made my living people private because I did not like surnames showing (bad for daughters who marry because they are identifiable) and very bad for Smart Matches because all details are provided. In doing so, the private people are still shown at MyHeritage in boxes but the big loss is that I, as site manager, can't see their data or edit them privately online, like I can do with living people who are not private. If the data is actually up there, then I think the site manager should be allowed to see it and edit it. Or alternatively, make living people a little more private, getting rid of surnames and info in the Smart Matches. In Smart Matches, allow matching to the living people by name only if they have the name, but don't supply extra dates, places, etc. or supply new people they don't have.

Louis Kessler replied to Blaine T. Bettinger's comment.
Group: The Visual Phasing Working Group
Adam - My gut statistical thinking says coincidence. But more missing from grandfathers could be due to fewer recombinations in males, thus larger matching and unmatching segments and it may be statistically less likely to fill in bigger regions than smaller ones. So I'm not sure.
Louis Kessler commented on Adam Nisbett's post.

You don't really need any more siblings. What you need to do now is to get some aunts and uncles and first cousins so that you can build up more of your great-grandparents. You do have 49% of each ggp right now but don't know which 49%.

Having GEDmatch figure out half identical regions and full identical regions would be good enough for me. Triangulation or lack thereof can identify mismatched segments. Likely people who do Visual Phasing would not be happy with this change.
Louis Kessler replied to his own comment.
Judy. No. When you are looking from white's point of view, behind white's pieces, the king is on the right and the queen is on the left, as in the diagram I show which is from the webpage you referred to. (The king is the piece having the crown with the little cross on top. The queen has the crown without the cross.)

But looking across the board at white from black, as in your image, white's king (actually both kings) should be on the left and the queen(s) on the right. Just as when you look at a person, their right hand is on your left.

To fix your image, it should be a simple matter of flipping it right-to-left (mirror image).

An ultra-pendant person (not me, I hope) would tell you that the queen must start on her own color and the king starts on the opposite color. I think that is not the way it is in your image right now, meaning the board is oriented correctly, just the king and queen need to be switched. But the color of the square the king is on is so hard to discern in your image that I think the right-to-left flip would be good enough.

Rob - Oh. You mean one report had 11 and the other had 18 conditions. Take a look at each report and see what variants the condition depends on. Then find those variants in your two VCFs and compare them to each other and to what the condition requires. That should tell you whether they are missing variants in one test or differing variants between the two tests.
Louis Kessler replied to Rob Knight's comment.
Group: Dante Labs and Nebula Genomics Customers
Rob. Not sure what you mean by an extra condition variant.
Louis Kessler replied to Rob Knight's comment.
Group: Dante Labs and Nebula Genomics Customers
Rob. I bet the reason for this is that the reads are basically random and all different in the two tests. Some areas of the genome will get more coverage in one test and less in the other. The variants with less could have been filtered out, and that would be the reason for the unique SNPs, indicating about 3% of the valid variants don't make it. That's understandable because they filter to eliminate false positives (non-variants incorrectly stated to be variant) at the expense of missing some (i.e. 3%) true variants. What you need to do to determine accuracy is to check how many of the variant values of the 3771740 shared SNPs are the same in both tests. I suspect a very high percentage will be the same. My conclusion is that this is a very good result indicating very good accuracy. Most of the unique SNPs on both tests are also likely valid variants.

Ann: Assuming the probability of a heterozygous SNP is about 30% as shown in the output, and that they are reasonably independent of each other, then whatever the probability of having 15 is, then the probability of 16 would be 30% of that, 17 would be 9% of that, 18 would be 2.7% of that, etc. The point is that the chance of getting many more in a row decreases exponentially and it is unlikely anyone naturally will get more than even 30.

Good question! If you have your mother, then DMT will at least identify for you all your matches that are not on your mother's side. To get anything more regarding your father's side, you would need to know MRCAs (most recent common ancestors) for at least one and preferably a few DNA matches on your father's side that are at least to the grandparent level. Having those, DMT can classify your paternal segments by those ancestral paths.

Thanks everyone, especially those who provided me with sibling dara. I worked for a couple of months to see if I could integrate visual phasing into DMT. But individual segment matches are a bit different than GEDmatch's One-to-one diagrams because the latter distinguishes half from full matches, whereas individual segment matches do not. None-the-less, I was able to figure out how to use sibling matches effectively in DMT. The key is to find half matching areas which is possible for many, but not all of them. It's the boundaries between half and full that I could not find a way to determine well enough, that is needed to implement VP using segment matches.

MyHeritage only draws the triangulation if all the people triangulate. So in your third diagram, at least one person doesn't triangulate with the others. So try taking people out until you get a triangulation, and then try adding them each again one by one as long as it remains triangulating. Also, does your 2nd diagram still triangulate if you add your father back in? (It should)

Group: Dante Labs and Nebula Genomics Customers
Nathan - Fair enough. But if that is truly the case, then short reads should have more trouble being aligned than long reads, even if they have fewer errors. But short reads seem to do just fine. And long reads should be able to do at least as well or better because each long read could be analyzed as 100 short reads Example: I have a book that is 3 billion letters long only made up of ACGT with lots of repeats in it. I give you a bunch of extracts that are 200 letters long with 1 variant, 1 insertion and 1 deletion plus 1 read error in it. Find where that is in the book. Now do the same for a 50,000 letter extract that has 15 variants, 5 insertions, 5 deletions and 1000 read errors in it. The long reads should be no tougher to find because 98% of both the short read values and long read values are correct. I think the problem may be that the statistical algorithms are tuned for short reads. Better algorithms tuned for long reads should be able to do a better job of aligning long reads. And if they are properly aligned, then the 30x will fix the individual read errors.

If so, we've got 27x coverage instead of 30x coverage. Doesn't seem like a big deal. This is just my logic working. I don't know exactly how they align the FASTQ to the standard genome to create the BAM file. If this isn't the way its done, then maybe new better techniques for aligning long reads are required, e.g. shorter parts of the long read are aligned separately and checked that when put together they are consistent.

If the "systematic read errors" are that bad, shouldn't they prevent this from being possible? And if the reads are now in a BAM file, why wouldn't my argument above be valid? I'm awaiting my long read results and I'm planning to compare to my short read results once I get them.

Group: DNA Painter User Group
Each segment match can have a bit of random matching of 1 or 2 cM at either end. So a bit of overlap might be real, or might not. Also realize that the end of each segment match is either caused by one of your ancestor's recombinations, or one of your match's ancestor's recombinations. If many of the segments seem to be stopping at one point and new ones starting there, then it may be your ancestor's recombination being the cause. So investigate with one-to-one comparisons to see if the top four pink matches match each other, and if the bottom 9 pink matches match each other. The two green matches may span the two pink sets if they are related through an ancestor closer to you than the ancestor who had the recombination.

Louis Kessler replied to Rob Warthen's comment.
Group: DNAGedcom User Group
Rob Warthen - I'm not sure where to find the "ICW sleep time". But I think my problem is because I have over 173,000 matches and each of my ICWs have lots and lots of ICW matches, maybe 100,000 or more due to endogamy. So it takes a long time to just get all the ICW's for one match. . What might work better is if you used the minimum cM not only as a stopping point for the matches, but also as a stopping point for the ICW matches. Then I could pick something like a 40 cM minimum where I've only got about 500 matches, and each match will have fewer than 500 ICW rather than 100,000 or more. Then I'll at least have a useful database of my closest ICW matches that I can use. That should run quite fast. I could then try lowering it to 35 cM or even 30 cM. But the time taken will grow exponentially as I lower the value.

There is also a Windows program that can create a raw data file for you from a Dante BAM file. It's called WGS Extract. I described my experience with it here: http://www.beholdgenealogy.com/blog/?p=3018
Louis Kessler commented on Joan Benson's post.
Group: Genetic Genealogy Tips & Techniques
Joan: As Marko just said, GEDmatch used to accept WGS VCF files for upload. I uploaded my Dante VCF file, which only includes variants from the human genome. GEDmatch's upload procedure only took the variant values and did not include the human reference genome values for other values. This caused me to match other people's WGS results almost perfectly, and give less than reliable results from everyone else. I reported this to GEDmatch and they agreed it was a problem and they later removed the ability to upload VCF files. So those were the results that were unuseable. To get accurate results, you have to use a utility to convert the VCF file into a raw data file correctly by filling in the missing values with the human reference values. DNA Kit Studio is a Windows program that will do it for you. Then you can upload the raw data file to GEDmatch.

Group: Genetic Genealogy Tips & Techniques
Ross - Okay. The number of segments grows linearly, with about 34 recombinations per generation. So after 14 generations, you'll have on average 23 + 34 x 14 = 499 segments. The odds of any one of the 499 segments being passed to 2 specific people 14 generations now is 1 in 537,000. But the real problem here is that the 499 segments average only 7 cM, so many of them might match by chance and it will be very difficult to identify a true IBD match from all the false ones.
Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
(I wondered why I couldn't comment on that post any more) Hopefully they do put Richard III's raw data on GEDmatch. And then we'll see if there are two people who triangulate on a segment with him. I personally don't expect to find two such people (if parent/children and siblings are excluded). But if we do, and if it can somehow be shown to be a not-by-chance match, then it is possible that the segment was IBD and inherited from him. Even so, the most recent common ancestor might have been a descendant of his, meaning the shared segment could be much less than 20 generations old.
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
Blaine - That would be very exciting. How do we make that happen?
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
Blaine - Well yes, every segment comes down some path from ancestors hundreds of generations ago. So segments themselves are old. But what I see that can't be that old is a segment match between two people. The maths simply says the same segment can't last that long since it is vanishing in an exponential manner (power of 2). Heck, even after 6 generations, you start having g5-grandparents that passed you zero DNA. Actually, I've been unable to convince many people about my viewpoint on this, with Jim Bartlett being the notable exception. And I'm happy to leave this as a friendly disagreement with you on this.
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
Blaine - The reason why the segment is very unlikely to survive 14 more times is because there is just a 1/2 chance that the segment gets passed down each generation. One grandparent or the other gets passed to the grandchild, so one grandparent's segment stops there. Therefore the chance that particular segment will get passed down 14 generations to one descendant is 1/2 ^ 14 which is 1 out of 16,384. The chance it gets passed down to a different descendant is also 1 in 16,384. So the chance the two 20th generation cousins both get it is 1 in 268 million. That is a very big ask. And it's the above reasoning and reading of Jim Bartlett's Segments: Bottom-up got me thinking about this and started me to wonder if Speed and Balding's large number of generations in a match was even possible, so I did the analysis. Actually, I had a prior article to the one I mention above. Look particularly at my article's comments section where Jim Bartlett, Doug Speed, and Debbie Kennett all comment. http://www.beholdgenealogy.com/blog/?p=2338
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
Blaine - I believe Speed and Balding's simulation overestimates the generations for small segments that we see in match data. Their analysis does not filter their matches the way FTDNA and the other companies do. I believe most segments that are filtered matches, even small ones, will be within 20 generations.

Oh I see. I didn't know you were ordering a new test. Mine is an upgrade price. I don't have to retest to get the health reports, so the pricing is different. Which is interesting, since my test was done before the GSA chip. So if I was interested in health, it would be useful for me to both accept the upgrade, and buy a new kit with the GSA chip, and compare the results. I'm not. But you might want to do the upgrade of your old kit as well so you can compare them.

Here's an example of two Triangulation Groups that butt up to each other. You can see that the first TG has one match that goes out as far out as 15,117,348 bp. The second TG has 5 matches that start as far back as 14,920,913 bp. So there is an overlap at the boundary of 196,435 bp. These are matches from Family Tree DNA, so you can see the discrete boundaries of their 100 SNP buckets in the Start and End positions. Many people get fooled that matching boundaries mean something special, but anything close to the unknown true boundary are likely the same crossover. The unknown and true crossover in this case likely is somewhere between 14,575,885 bp and 14,920,913 bp. But determining that exactly does not provide you with any really useful information for the purpose of TG determination.

Adam - In practice, that will be rare. 7cM random matches occur in an unrestricted environment where any two segments of any two people can be compared. But random extensions happen at the end of a match, where one parent is known to no longer match so the random half match is less likely. 99% of the extensions I've observed are less than 1,000,000 bp.
Louis Kessler replied to Jonathan Brecher's comment.
Group: Genetic Genealogy Tips & Techniques
Jonathan Brecher - you are correct that the true (unknown to us) crossover occurs somewhere.and gets passed down exactly through the generations. But it is the identifying of half matches that is inexact and will extend the boundary of the match differently depending on who you are matching to.
Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
I have found that start/end segment match positions can extend the match at either or both ends, as much as 750,O00 base pairs or about 0.75 cM due to random matching. This means that two matches that should line up with one starting where the other ends, might in fact overlap by as much as 1,500,000 base pairs. It is not a bad idea to round your segment boundaries when determining triangulation groups to the nearest million BP, as Jim Bartlett recommends.

Ted - You totally misread what I said. And you'll never get true half-identical runs of base pairs. WGS is not anywhere near being 99.999999% accurate. Each estimated base pair has its own accuracy estimate in WGS. And all these mis-assignments of the ones that are in fact inaccurate would do huge damage to the type of matching you are proposing.
Louis Kessler replied to Ann Turner's comment.
Group: Dante Labs and Nebula Genomics Customers
Ted - So you have a rare or novel variant in the midst of a million consecutive base pairs that are half-identical. How will that help? Surely you wouldn't break the match in two because of it. And non half-identical segments will likely have about 100 different SNPs every million base pairs, so sticking a few novel variants in there won't do much either.

I appreciate all the different ideas. Most people use a surname system like Drew suggests and it works for them. Some people, like you Jan, use a source-based system and it works for you. I use a "where I got it / repository" system. I want to know everything I got from a person, a facility, or a website. Also, I never split material up. All photos and documents I got from from one person or place stay together, which is what archives do. Sometimes the order and relationships of items (e.g. photos in an album) are important clues, so I always have them together this way. Also, I don't have to do the extra manual labour required to divide them up. My physical items are stored exactly the same way. So my folders are person, place or website I got it from. Filenames are: SourceType-Surname_Given-Year e.g. Census-US-Smith_George-1910

Ann. You say: "In the best of all possible worlds, he would have the same list of matches using his phased kit." Wouldn't your match be based on all 23 pairs of your chromosomes (i.e. both parents) whereas your son's phased kit would only be based on one of your parents on each segment of each chromosome. So wouldn't his phased kit have half the matching potential of yours and thus have fewer matches and less total cM per match?

Ann: About a month ago, I used a program called WGS Extract to create a raw data file from my BAM file of my Dante short read WGS. I found the results only agreed with the (non no-calls) of my SNP tests for 98.1% of the SNPs in common. The numbers were a high of 99.5% for AncestryDNA, down to 98.5% for LivingDNA to 97.2% for MyHeritage to 96.8% for FTDNA to only 95.7% for 23andMe. For the differences, either the WGS is wrong, or the SNP test is wrong, but I can't tell which. Doing the same with the long reads will give me a 3rd data value that in most cases should agree with either the short read or the chip tests and allow me to determine which one of the three is likely wrong. http://www.beholdgenealogy.com/blog/?p=3018

I looked into those 3 of my top six who don't triangulate. I did some X one-to-one comparisons and there is no X match according to that. Not only that, but my uncle does not match me anywhere on the X according to the X one-to-one. I had heard before that the 1 to 1 gives different results than the 1 to many does. (Can't remember exactly why). But this is a bit disconcerting none-the-less. Let's see if I can break the tie. Are these real or not? I ran a segment search on my X between 123 Mbp and 141 Mbp. I got 50 matches. My uncle was not in there. And of the 101 people who supposedly match both myself and my uncle on that segment, only 8 of them were included. The average cM match of those 8 were each about twice as much as what the one-to-many gave. Of the 3 people who were supposedly triangulating with me and my uncle, only 1 was a match to me on this segment according to the segment search. So these three different reports at GEDmatch: 1. One to Many 2. One to One 3. Segment Search unfortunately give me 3 very different results. This takes away a lot of confidence I have in GEDmatch's results. Small inconsistencies would be acceptable. But these are big inconsistencies.
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
Okay. It took about 20 hours but now my kit's matches have populated. When I run myself, I've got 1,819 X matches with limit 3000 compared to my uncle's 1,790 (a decrease of 3 from yesterday). So now what happens when I compare my matches to my uncle's. He's my father's brother. So his X is from his mother, who is my father's mother. My matches are from my mother. So theoretically, we should not have very many matches in common. Of course Ashkenazi are endogamous, so you would expect matches. On the other hand, for myself when I do the GEDmatch's "Are Your Parents Related?", I have just one homozygous segment > 7 cM that's 8.8 cM and the estimated number of generations between my parents is 9.8. So the conclusion is that my parents are at most only distantly related. I can see that as a possibility, even with endogamy. My Dad's family is from Romania, and my Mom's is from the Ukraine, more than 200 miles away. So maybe I won't have many X matches in common with my uncle. Let's see... Well it turns out I have 101 people in common between my X matches and my uncle's. My largest X match is only 38.2 cM. I have to go down to 21.1 cM before I get to my first X match that my uncle and I have in common. It is 21.1 cM for both of us, which is quite indicative that we got the same segment. In fact, and I'm quite amazed by this, but every single one of those 101 people have exactly the same amount of X match for my uncle as for me. And they are all on just 1 segment (because total = largest) ranging from 21.1 cM down to the lower limit of 7 cM/ What I'm guessing this means is that my father's mother and my mother must have got at least a 21.1 cM segment on their X chromosome from the same ancestor. X' segments tend to last longer, so this could be quite distant, maybe 10 or 20 generations back. But I do have 101 people I can work with to examine this segment in detail and see if I can find a commonality. When I do a multikit analysis and take myself, my uncle, and the 6 kits we both match largest on our X segment, and use the GEDmatch Triangulation visualization tool, I find that sure enough, 3 of the 6 are all triangulating with my uncle and me and with each other between 123 Mbp and 141 Mbp on everyone's X segment. Wow. Neat. So isn't it sad that the East European records only go back about 5 generations. That will make it hard for me to genealogically find who the common ancestor between my father's mother and mother is, especially since I don't know how any of the 101 people are related to me.

As much as we'd all like a standard reference and would want everyone to use the same one, as soon as a new revision or patch to a revision comes out, we are no longer current. Staying current and consistent is impossible. Even being hg38, you have to ask: which patch? For health and Science purposes, yes you'll want the up-to-date version. But genetic genealogy testing companies have agreed on hg19 which is fortunate because they can share amongst each other. They only test selected SNPs and for them, it's more important that they have a standard other companies use than it is for them to have the latest and greatest mapping. As long as their SNPs which are relatively far apart from each other (which is done on purpose) are mostly in the correct order, then they can find segments of matching DNA, which is all they need to do.

Well, they do say when you run it that "To conserve system resources, matches closer than 2100 cM will not be shown." If that's the reason, that's ridiculous. It would take no more time to compare a parent, sibling or child to yourself than comparing anyone else to yourself. They are using your 1000 closest matches which for me generates 6257 segment matches. If instead of using matches 998 to 1000, they used matches 1 to 3, it would add maybe 60 more segments to the file, about 1%. There must be some other reason.

Allele frequency was used to select the million or so SNP candidates.

Of the million or so SNPs GEDmatch uses, which are the ones that differ the most in people, GEDmatch does this: It takes the SNPs in common between two people, and looks for runs of half-matches.

Hi Moishe. I'm also K1a1b1a for HVR1, HVR2, Coding Regions. I have 395 matches at GD 0. That's almost 16 full pages of 25 per page. So I'm very surprised you have none. The mutations can happen anywhere down the line, so you might have had a mutation on your maternal line only a few generations ago. If so, then your GD 1 are functionally equivalent to my GD 0. I can trace my maternal line back to Silverberg in the mid 1800's in southern Ukraine. But I cannot connect genealogically to any of my GD 0 matches.

Cyndi - The first genealogy "program" I used was the Tex word editor on the IBM 370 mainframe at my University. I used one of the classic numbering systems combining ahnentafel numbering and children numbering. It gave an index of all people by number at the end. Even though it wasn't WYSIWYG, e.g. you had to enter .p for paragraph, .i for index, etc., and then run it to see the result, it still was so much nicer than the genealogy programs that came out that were nothing more than clunky database programs. i still have some of those printouts in my closet somewhere.

Thanks, Ann. You're right. The GT field also would have given me the information … if it was provided to me in my gVCF file. Unfortunately, every value in my file for that field is "./." The image shows two SNPs from my gVCF file, both are variants. The first is CT the second is CC. I know that from both my filtered and my Raw VCF file and from my WGS Extract. But I can't see a way to tell from my gVCF file, since the AC field is not included and the GT field has no value. I've looked at all the other fields in my gVCF file and entries that leave out the BaseQRandSum and ClippingRankSum fields as the second one in my image are often homozygous, but I've found several thousand exceptions to that "rule". So either one of the AC or GT fields do allow easy determination of the values of the variant. But neither are in the gVCF file Dante gave me.

Group: Dante Labs and Nebula Genomics Customers
…Regarding my 2% rate. That is both made up of chip errors and WGS errors, and I can't separate the two yet until I get my 3rd source (Long Read WGS) to compare each of them to. WGS itself does not give values that are true or false. It gives various quality measures on each read. So there are several different sliding scales of 0 to 100% that they include on the expectation that the read is correct. And which reads are included is entirely dependant on the filter selection of quality measures. Different results will come with different filter selections. I personally like the chip method better. They also use a filtering method which they hide from us. But they take low likelihood reads and deem them as no-calls, which I'd love to have in the VCF files instead of the questionable variants simply being left out.
Louis Kessler replied to Ann Turner's comment.
Group: Dante Labs and Nebula Genomics Customers
Ann - Very interesting regarding your high concordance rate (99.923%). My results tend to agree that the variants listed in the filtered VCF file are almost all true variants. This does seem to indicate that the filtered VCF file is very accurate with regards to only including true variants. But that is because the filters are extremely conservative. The filters ensure that it is only including what it is certain is a variant. But by doing so, it is also excluding a lot of true variants. Look in your combined microarray file to see how many heterozygous SNPs you have that are not listed in the filtered VCF file. All of those (except the ones the chips got wrong) have to be variants. I guarantee there will be a lot of them. 2.3% of my SNPs were heterozygous and not listed in the filtered VCF file.

Ted - If we in our population have 0.5% chance of having a variant, then two random people in our population have a 0.0025% chance of both having the variant. If one of our common ancestors, say a 6th great grandparent had the variant, then there is a 0.4% chance that I got it from him, and a 0.4% chance that you got it from him. And even if you and I got the same variant, then it's quite possible that you got it from a different 6th great grandparent, and each of them got it from our 12th great grandparent. That will be impossible to trace genealogically. But here's the catch. You put enough people in a pot, and enough rare variants, that some people will match on those variants. Even though most descendants of those ancestors with the variants will not get the variant. It's a puzzle we are unlikely to solve. But I love your thinking and ideas about it. I could be wrong and you could be on to something.
Louis Kessler replied to his own comment.
Group: Dante Labs and Nebula Genomics Customers
Ted - WGS isn't perfect either. There are lots of misreads. Long Read technology even have more. Any individual SNP can be read incorrectly, or matched to its position incorrectly. Then there's insertions, deletions, mutations. I'm looking now to compare the filtered VCF, raw VCF and gVCF files. It seems that you can select the level of "quality" of a match when you produce the VCF, so there is no one absolute measure of whether a SNP has one value (non-variant) or whether it has the variant value. It is more of a continuum. Do you want more or less variants? Fewer false positive and more true negatives, or fewer true negatives and more false positives? The DNA companies say they are happy if they can give you 99% accuracy with fewer than 5% no calls for matching purposes with chip tests which is quite adequate for matching when you use the 1 in 100 allowance for SNPs that may be wrong. That of course is not good enough for medical purposes, but my initial analysis seems to indicate that even my WGS results may have about a 0.2% error rate. Again, it is hard to classify an exact error rate since every read has a quality estimate, admitting they are not perfect.
Louis Kessler replied to his own comment.
Group: Dante Labs and Nebula Genomics Customers
Ted - You're expecting that the miniscule effect of matching maybe 80 extra SNPs over a genome with someone will have huge effect which it won't, because it will be negatively offset by the hundreds of extra indels and mutations that won't match. Chip based matching today has the right level of fuziness in its matching and finds matching segments just fine. Allowing one false positive or one true negative every 100 or so SNPs keeps it from becoming too OCD about any particular SNP. Those far away relatives are not going to be revealed to you at all with DNA no matter how many SNPs you compare.
Louis Kessler replied to his own comment.
Group: Dante Labs and Nebula Genomics Customers
Ted, for genealogical matching purposes, long stretches of raw DNA can be phased with the raw data of parents, siblings aunts, uncles and cousins. That is easy to do today with tools like Kevin Borland's and much more effective than the current technology of long reads can be. And triangulating segments effectively phases them even without the raw data. So I don't see WGS matching, even with long reads, adding much for genealogy. GEDmatch already does fine with 700,000 SNPs. If we're cousins at FTDNA, feel free to send me your segment match file and I'll add you to my triangulation groups.

Ted - I know there are millions of rare SNPs. But my quick calculations above indicate that the average person would only have 80 of them. Just 80 additional SNPs spread across the genome would not help in matching even one segment, since a tolerance of something like 1 mismatch out of every 100 SNPs in every matching segment is allowed in segment matching to account for misreads, indels, mutations etc. What helps segment matching the most are SNPs that have the most variation among people, not the SNPs that are variants among a fraction of a percentage of the people.
Louis Kessler replied to Ted Kandell's comment.
Group: Dante Labs and Nebula Genomics Customers
Ted - Interesting thinking, but I don't think they'll help much. It is estimated that WGS will only improve the accuracy of shared matches between 5% and 15% over what the chip tests now do. Even if people had millions of these rare SNPs, then the average person would have 20 million (number of rare SNPs) x 1/400 (Ashkenazi out of world) x .1605% = or about 80 of these rare SNPs. They would be spread around the genome and thus not help any individual segment match.

Even if these SNPs were truly bogus, 514 SNPs is less than 1 in 1000 of those tested. The matching algorithms of the various companies allow 1 or 2 mismatches per 100 SNPs in a match to account for misreads, mutations, indels, etc., and they require several mismatches per 100 before a segment is broken. So it is likely these would not change any of the resulting matches.

Joachim - No, because the stretches between two heterozygous SNPs is often longer than the longest reads. Therefore the long reads cannot span this region and align the chromosomes on either side. The aligned regions are called contigs. The unaligned stretches between them are called scaffolds. There are various algorithms for scaffolding (aligning the contigs) but they are all far from perfect. Long reads can sometimes give you as few as several hundred contigs if you're lucky.

I can get down to 20 kits in 7 clusters using 75 cM to 400 cM, but that still doesn't help me identify what they are. The problem is moreso that I don't have anyone closer than about 100 cM at GEDmatch, whereas I have better luck with clustering at Ancestry and 23andMe where at both sites I have about 10 known 3rd cousins who've tested that allow me to identify most of the groups.

Those were the default 15 cM to 50 cM settings. I tried various other ones and 70 cM to 400 cM seem to work the best for me, using 50 kits giving me 19 clusters. Unfortunately, I can't identify any of the sides any of the clusters belong to since I don't know any of the people included.

Ted - Yes, you are correct that YFull uses hg38. But YFull is a specialty Y-DNA analysis that most genealogists don't need to or have the desire to get into. The Y-matches at Family Tree DNA are good enough for them. And yes it is easy to convert the hg37 positions to hg38. A company like Ancestry likely can do it for their 15 million tests in a few days of processing time. The problem is recreating their segment match database of 15 million x 15 million / 2 = 112 trillion pairs of people that need to be compared over the 700,000 SNPs. That would take a very long time. And what benefit would doing that provide to make it worth it?
Louis Kessler replied to Ted Kandell's comment.

The genealogy world and DNA tests for genealogy matching are all based on hg19. That's 25 million DNA tests all compared on hg19. There is almost no benefit for them to switch to hg38 but lots of cost to do so. So cousin matching may stay hg19 forever.

Ann: I checked and I had 687 SNPs on the X and 1 on the Y that were in the pseudoautosomal regions. But I got lucky because the way I created my pivot table had correctly excluded them. So the table in my report was correct and I've added a note that the pseudoautosomal regions were excluded. Interestingly, only 140 out of those 688 SNPs in the pseudoautosomal regions were heterozygous. And the VCF did not have any of those positions in it, which I would think, it should have.

Jo: When you do a whole genome test that gives you all your 3 billion DNA positions, the VCF file you get from it gives you just the differences from the human genome reference. People who do whole genome tests currently don't have a good way to convert VCF files to the SNPs that they can upload to FTDNA, MyHeritage or GEDmatch so that they can find relative matches. My question to Ann was why can't we fill in the SNPs not in the VCF file with the human reference values.

Here's my Genetic Affairs Ancestry run 1200 to 90 with my extreme Ashkenazi endogamy. It actually doesn't do too bad, giving me 7 groups, 5 of which I can identify. The "Mother" group includes a first cousin (1,047 cM) and a first cousin once removed, so they represent two grandparents.
Louis Kessler replied to his own comment.
Group: Living DNA users
None of my "3rd cousins" are 3rd cousins or I would recognize them. Due to endogamy, they are all likely 10th cousins 20 times over and the cumulative "population" matching makes them look like 3rd to 4th cousins. I figure my zero matches at DNA.land is a glitch. I should have the 50 like my uncle but I don't for some reason. I should match to half of the people my uncle matches to there plus another half on my mother's side. I bet a lot of people have zero matches there just because of the "glitch". Might be worthwhile reuploading if you've got zero. I didn't have my uncle's DNA uploaded to LivingDNA. I'll do that now. I'd guess LivingDNA at about 250,000.

Bill - DNA.Land limits you to your 50 closest matches. My uncle has 50 there with the 50th at 48 cM. By comparison, I have 149 matches at LivingDNA down to 50 cM. My uncle likely would have a few more than me because he is a generation back, so that's at least 3 times a many for me at LivingDNA than at DNA.land. But using that to estimate number of testers doesn't seem right, since I only have 56 AncestryDNA matches greater than 50 cM, and it's obviously not correct to say that LivingDNA's database is 3 times bigger than Ancestry's.
Louis Kessler commented on Bill Cazemier's post.
Group: Living DNA users
Here's my results with my endogamy. Note that there are a few things to consider when you or anyone else does a comparison of your number of shared matches. First, the Minimum cM each company goes down to in their matching is different. Living DNA only goes down to matches of 37 cM for me. Comparing my number of matches at 50 cM or higher, you'll see I have more matches at Living DNA than I have at AncestryDNA. But that's because Ancestry uses their Timber algorithm to eliminate many segments they think is false. But I match 161,964 people at Ancestry because they go down to people who match just 6 cM (one segment). Family Tree DNA gives me over 15,000 matches at 50 cM or more, because they include small segments in their totals. In other words, each company uses different algorithms to determine what they consider a match. So it is not really possible to fairly compare matches between them. DNA Land does not show any matches for me, which is strange because they show 50 matches (their limit) for my uncle, down to 48 cM (of what they call Total Recent Shared Length).

Hmmm. Try this: Assign half of each of your ethnicity percentages to your father and half to your mother. Do the same for your half brother, assigning half of each of his to his father and the other half to his/your common mother. Now your mother has an estimate based on both of yours which should be slightly more accurate for her. Divide that in half and subtract it from each of your ethnicities again to get a better estimate of your father and your half brother's father. Some values may be negative, but it's only a rough estimate based on an average. It should still give you a slightly better estimate for your half-brother's father.

Louis Kessler replied to Evert-Jan Blom's comment.
Yes, I will be looking for differences, and where they are I'll check the reads of each test to see if I can figure out why.

The long reads won't be long enough to span all the equal areas between the heterozygous SNPs, so phasing into parental chromosomes isn't directly possible, but I'm hoping there will be some long contigs. There are some scaffolding techniques that are supposed to be quite good at aligning contigs. Not sure if I can get that far, but it will be fun trying.

Neither my X or Y values should be heterozygous. And I checked and those readings are not from my Pseudoautosomal region.

So it might represent the error rate of WGS, which for my X readings would be 626 / 71327 or 0.9%.

Louis Kessler commented on Wim Penninx's post.

Also, long reads are still not long enough to separate the two chromosomes. The reason is that because humans are 99.9% identical, you'll get long stretches of DNA, longer than the long reads, where both chromosomes are the same and the long reads going into these regions cannot be correctly associated with the long reads coming out of it.

Yes, Ann is correct. Poorer quality matches get eliminated. "Of the 3,000 matches to my 23andMe kit, 611 of them were not also matches to my All 5 kit.

That means over 20% of the matches were refuted or at least found to be not as good as they were originally stated to be after I improved my overlap count with the combined raw data." Of the 2,389 matches in both, about 16% of them had different total cM values, and for those that were different, the matches with the combined kit was on average 7 cM less than the 23andMe kit.

Blaine - I think what I said I was accurate. And what you say is accurate as well. I think we are just saying different things. You are saying you have segments from common ancestors that were NOT passed down to 3 different people. That's fine. In that case you do not have any 3 people that triangulate on that segment because that segment was not passed down to all three of them. I'm saying if you have segments from common ancestors that were passed down to 3 different people, then they must triangulate. I'm not trying to say that all ancestral segments must triangulate by some three people somewhere. I do agree that many ancestral segments will not have been passed down to three or more descendants who have DNA tested. And therefore that ancestor's segment will not be found to triangulate (due to being passed down) by any 3 people.
Louis Kessler replied to Wim Penninx's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Long reads provide no help for relative matching. Matching is based on the 700,000 or so SNPs that a company tests. Those SNPs are spread out over the 3 billion base pairs of your genome. The standard DNA tests you take do a good job of identifying those SNPs for matching purposes. WGS (Whole genome sequencing) whether short reads or long reads are for determining the 3 billion base pairs and finding all the SNPs where you vary from the human reference, which can be several million. The SNPs other than the 700,000 the company tests are not used for matching, so getting their values does not help matching.

Triangulation does not "prove" a common ancestor for a segment. It's the other way around. All segments that come from a common ancestor must triangulate. So any segment that does not triangulate cannot come from a common ancestor. ---------------------------------------------------- Update: The discussion below revealed to me that many people don't automatically associate segment triangulation with overlapping segments at the same location on a chromosome, so let me rephrase the above to be: Triangulation does not "prove" a common ancestor for segments at the same location on a particular chromosome. It's the other way around. All segments at the same location of a particular chromosome that come from a common ancestor must triangulate.

Well that's the first time I've seen a number larger than 5 million from them. Either 23andMe is not very good at maintaining consistency in their reported numbers on their website, or they have very different meanings for "customers", "genotyped customers" and the number of "people who have spit". On the same Media Center About page you link to, in their bottom graphic, the last entry they have is April 2017 when they say they surpassed 2 million genotyped customers. You'd think they would have already added one or more 2018 and 2019 entries to show the progress towards 10 million if that number is in fact true. At the bottom of their https://www.23andme.com/dna-ancestry/ page, they answer a question: How large is the 23andMe DNA Database? and their answer is that "the 23andMe DNA database has more than five million genotyped customers worldwide."

If shared matches or ThruLines or triangulation helps you find a genealogical connection with someone else, then it has done its job.

I plotted Gen vs Total cM and it tells a lot. Note the Total cM is plotted logarithmically. 1. The lowest Gen possible for a given Total cM is predictable. It is linear to the log of the Total cM. The equation is Lowest Gen = 6.9 - 1.66*log10(Total cM) 2. For a given Total cM, the Gen can have that minimum value, or be higher. 3. The 3,000 matches included are cut off based on the Gen value, not on the Total cM. In the example I plotted, the cutoff was a Gen of 5.2

Blaine: In my article, shared match clustering gave me one big cluster because of endogamy, so I didn't get anything at all from that. But Evert-Jan's TG clustering gave me 4 clusters, so mine is a situation where the TG clustering provided me information where shared match clustering did not. I noted that the TG clustering did split up a family into 2 clusters which is a problem. But I failed to mention that the 4 clusters are still good clusters, where the people in each cluster do appear to be from the same family. So there are uses of this second technique as well. Maybe Evert-Jan can figure a way to parlay the information that the TG clusters have to make the shared match clustering even better.

For understanding, I really like the explanation Jim Bartlett gives in his Crossovers by Generation article https://segmentology.org/2016/02/02/crossovers-by-generation/ where he explains that segments grow in number linearly (averaging 34 per generation) but ancestors grow multiplicatively (by 2 per generation). Ignoring pedigree collapse, by the time you go to 5g grandparents, you have about 227 segments that came from 64 ancestors. If you assign those 227 randomly to each of the 64, you can see how a few might have passed 6 or 7 or more segments, and one or two might not have passed any. By the time you get to 8g grandparents, you have about 329 segments for 512 ancestors. That means that at least 183 of your 8g grandparents (36%) did not pass down any DNA to you. And 95% or more of your 12g grandparents did not pass down any DNA to you.

Jérôme Bellon - I doubt very much that these are two recombinations at the same position. What's much more likely is that your father & uncle's grandparent shared the full segment with their 2nd cousin. That segment got divided during recombination when passed down to their parent, with the left part on one chromosome and the right part on the other. Your father then got his segment from one chromosome and your uncle from the other.

Jonny, good point about 1st cousins. You can't simply use their matches alone. In my case, I'll be using their matches only when they are matching to a person that I know is related through one of the grandparents my cousin shares with me.

The tool is Wilhelm HO 's DNA Kit Studio, a free Windows program. It can combine your kits for you.

You'll need to have a few people whose relationships you know to be in at least some of the clusters. If you do, then you try to genealogically determine if other people in the same cluster have common ancestors with you and those people you know. With Ashkenazi, it's difficult mainly because our records usually only go back to the mid-1800's and valid cluster connections are usually further back than that.

Paddy - Well, we're all really guessing here. But my thinking is that because some kits have so little overlap, that GEDmatch Genesis will not group together matching SNPs that are some specific distance away from the next one (or further) even if there isn't a non-matching SNP in between. So maybe there's a big 5 cM segment in the middle of that 18.5 cM segment match where all the SNPs from both people were slimmed.
Louis Kessler replied to his own comment.
Group: GEDmatch.com User Group
Paddy - I doubt it. Usually only about 25% of a person's SNPs get slimmed, so .75 x .75 x 4,700 is still enough SNPs that would be considered a match. I'm thinking that part of the segment in the middle becomes a gap because of this, and the two segments left are both under 10 cM.

Blaine, a couple of years ago, I did a parent-child filtering study and found that technique provided mostly valid segments down to 7 cM.

Gila - most false matches can be screened out by triangulating which generally will reduce the cutoff for mostly legitimate matches down from 15 cM to 7 cM. At GEDmatch you can use their triangulation tool, or check a third person's match against two others using one-to-one comparisons.

Ann - Sorry, I don't understand your statement. The reference sequence has the common allele, not the rare one. The VCF file has the variant (i.e. less common allele). Having the reference SNPs is important. e.g. Here's an example where two kits both have two reference SNPs: Ref A, Kit 1: AA, Kit 2: AA Ref C, Kit 1: CC, Kit 2: CG Ref C, Kit 1: CG, Kit 2: CG Ref A, Kit 1: AC, Kit 2: AA What should happen here, and what will happen with normal kits are that 2 SNPs (the 1st and 3rd) will match and 2 SNPs (the 2nd and 4th) won't match. By leaving out reference SNPs, then in the example, the VCF file for Kit 1 would only include the 3rd and 4th SNPs and GEDmatch would only compare those 2 SNPs and see one match and one not match. The other match and non-match are not seen by GEDmatch. If both Kit 1 and Kit 2 are WGS kits, then only the 3rd SNP would be compared and it matches. Comparisons of the other 3 SNPs is lost. The other match and two non-matches are not seen by GEDmatch. GEDmatch doesn't need to fill the entire genome with reference values. They only need to load the 1.2 million or so SNPs that GEDmatch considers useable. If 500,000 of them are filled by the variants in the VCF file, then they should load the other 700,000 with the reference. This would not be at all difficult for them to do. That is because the WGS knows all the SNPs. By leaving out the reference SNPs, GEDmatch is needlessly missing SNP comparisons that it could make, thus artificially reducing the overlap when it needn't and in fact shouldn't. The overlaps of my WGS kit with other WGS kits is only between 90,000 and 110,000. That's not terrible, but it is much worse than the 150,000 to 320,000 overlap between my All 5 kit and other kits. A WGS kit knows all SNPs. It should the highest overlap of any kit, not 1/3 of the overlap. If a new chip comes along, hopefully the 1.2 million or so SNPs that GEDmatch selected as "usable" still work well. If not, they may have add to the usable list. They would only do that if they had to, because it would be another recalculation of all matches. But if they did, adding a few more SNPs to the reference would be small potatoes.

So my theory as to why I get complete matches with other WGS files is that conditional that you have a variant at a position and someone else has a variant at a position, there is an extremely high probability that your variant is the same.

Ann - Zero. All the RSIDs are shown as a period. Here's a bit of the file. So GEDmatch has to be matching on Position, not RSID.

No. After a night's thinking, I'm pretty sure what's going on. I think they are only loading in the VCF SNPs. Because of that, of all my 3,442,712 variant SNPS, only 590,334 of those fall among the ones they call usable. And those again get slimmed to 231,588. So all they are comparing in my WGS to other people are those 231,588 variants. Well, they are doing the same with all the WGS kits of other people as well. My WGS overlaps with other kits (in the ones I show above) only 99,630 to 113,999. I.E. we don't have the same variants. But my WGS kit and the other WGS kits match at between 3554 and 3564.8 cM. The reason for that is that most SNPs only have one common variant. I've seen that in SNPedia for many of the SNPs I've looked at. If there is a 2nd or 3rd variant, it usually has very low probability. So if they are only matching our variants as they appear to be, then we will be close to identical because almost all our variants match. I know how to prove this as well. I'll take my All 5 kit, and find all the SNPs that are in it but not in my VCF file. Those will be all the reference SNPs that Build 37 has which are not in the VCF file. Then I'll add about 1,389,750 - 590,334 = 799,416 lines containing reference SNPs to my VCF file. I'll make sure it is sorted and looks like lines in a VCF file. I'll upload that to GEDmatch as a research file and I'll bet that GEDmatch now will handle it fine. Even the matches with other WGS files will be fixed. If that fixes everything, then it will show that GEDmatch is only loading the variants and not adding the reference values for the SNPs they use that are not in the VCF file.

Collins and Shared Segments only ran well after I had the data. To get the data for them, I needed DNAGedcom. And I needed to run DNAGedcom on my own computer for almost 6 hours to produce a 119 MB ICW file with the results. And that was only after I had run it for 32 hours straight before I figured out that I needed to cut it down to a 40 cM limit. That's a lot of time to end up with just 242 matches.

I'm not exactly clear what you're looking for in the comparison. Do you just what to see which cousins are in common on each discrete segment? Double Match Triangulator takes segment matches of Person A and compares them with segment matches of Person B. It will show you all the triangulations with all People C who match both Person A and Person B on the same segment.

David - Whoops. Yes you are right. I was just calculating the chance that none of the segments would subdivided. But the question was about all the segments being passed, and yes, each segment has a 50:50 chance of being passed to the child. The expected amount the child would get would be 50%. The chance that (in my example) of 10 segments all being passed down would be 0.5 ^ 10 = 0.001 or one tenth of a percent. So it is a very small chance that the child would get all the segments that the parent had.
Louis Kessler replied to David O. Williams's comment.
Group: Genetic Genealogy Tips & Techniques
David. No problem. But the way I was reading your answer, it sounded like you were implying there was only a very small chance that all 84 cM would pass to the child. But 41% is 2 out of 5, so it often happens for that amount of total cM.
Louis Kessler replied to David O. Williams's comment.
Group: Genetic Genealogy Tips & Techniques
David, you're close, but not quite precise. For segments less than 70 cM, the percentage chance of them subdividing is approximately equal to their cM and the percentage chance of them passing whole is 100 less the cM. A 40 cM segment has a 60% chance of passing whole. A 20 cM segment 80%, a 10 cM segment 90%. So if she has 84 cM with longest 14cM, then if thats made up of one 14cM, five 10cM and four 5cM segments, the chance of the mother passing all down is: 0.86 * 0.9 * 0.9 * 0.9 * 0.9 * 0.9 * 0.95 * 0.95 * 0.95 * 0.95 = 0.414. So this particular configuation would give a 41% chance that all segments get passes undivided, but should be close to what the average for all configurations making up 84 cM with max 14.

If you compare your raw data from tests at different companies, you'll find of the SNPs in common that are not no-calls, very few, no more than 100 out of hundreds of thousands, have different values. For matching, DNA companies have a tolerance and allow about one SNP mismatch every hundred, so two tests at the same company should almost always produce the same matches. You'd be better off testing at a different company to get a different pool of people to match to.

Blaine - Matching smaller segments is just a minor benefit of phasing. The major benefit is that you'll know that any people whose phased segments match you on a phased segment are all from just one of your parents and thus will fall on the same ancestral path and likely have common ancestors with you and each other. No triangulation would be necessary. Just looking at the overlapping matches in a "phased" chromosome browser will tell you.

Blaine - There is one improvement to WGS that is not there yet, but it is coming. That is long read WGS where instead of reads of 10 to 500 contiguous bp, they read 1000 to 100000 bp. By overlaying these, they can phase parts of the chromosome. Unfortunately, long runs of homozygous bases can break the phasing, but techniques for scaffolding (aligning the two phases on either side of the break), or even longer reads in the future may get around this. So potentially, through long read WGS, we may one day be able to order a DNA test with each chromosome phased for us. https://www.researchgate.net/publication/318467001_Scaffolding_of_long_read_assemblies_using_long_range_contact_information

You get to be an insider either by entering a competition (like Jonny), being a speaker, or being an Ambassador. Unfortunately, it may be too late for any of those for RootsTech this February in SLC. So you might wan't to plan on RootsTech London in the summer or RootsTech 2020 in SLC. You need to apply for insider-ness about 6 months before during the short period they accept speaker proposals and ambassador applications. Competitions they sometimes don't have in place until a few months later and you've got to be ready for them, and then quickly make the decision to apply. If you want to try to get in to this year's innovation contest, they might still let you in late if you push them and with some good words from a few people like Jonny and me. But then you'll want to spend the next two months planning and preparing for RootsTech. For sure, go if you want. It's a great conference. But I think it would be very hectic for you to try to get into the competition at this point and you might want to wait for the next one where you'll have time to plan it all out. Or if you prefer madness and mayhem, go for it now.

Group: GEDmatch.com User Group
Because Living DNA and FTDNA have small SNP overlap (you said 158921), some SNPs may not be close enough to be considered part of the same segment match, and GEDmatch might have split the segment. The gaps between them might have reduced the total match cM to move it down to the parent/child category. The way to tell is normally self to self should just be 22 segments. If you have more segments matching than that, then gaps were added. And you'll see the gaps in the one-to-one graphic.

Jérôme - In AncestryDNA's raw data, the X chromosome is called 23 and 25 (the latter for SNPs at the tips of both the X and Y), the Y chromosome is numbered 24 and mt (Mitochondrial) is numbered 26. So between AncestryDNA and 23andMe, compare 23 and 25 with X, 24 with Y, and 26 with mt. For my data, they only have 16% of the X in common, 28% of their Y in common and 6% of their mt in common. Your results in your screenshot above are strange showing about 50 SNPs on chromosome 25 all with no calls. For my chromosome 25, my AncestryDNA raw data has just 500 SNPs and only 1 of them is a no call. So I don't know why you've got so many no calls there. My AncestryDNA included 650,410 SNPs. You should have something like that number. You shouldn't be having a million or more SNPs. They don't test that many. Are you sure that's not the number in your combined AncestryDNA/23andMe comparison file?
Louis Kessler commented on Jérôme Bellon's post.
Group: Genetic Genealogy Tips & Techniques
Yes, as Roger says, Ancestry displays 0 0 in their raw data format for no-calls whereas most other companies display two dashes: -- For matching purposes, a no-call is always treated as a match. My own AncestryDNA file had 2,893 no-calls which is 0.4% which was the fewest of any company. My raw data file from other companies had between 7,097 and 21,176 (1.1% and 3.0%) I'm surprised all the mismatches you had were no-calls on the AncestryDNA side. Didn't you have some mismatches because of nocalls (two dashes) on the 23andMe side?

MyHeritage is more convenient by showing circles around the triangulations when you select the three people in the Chromosome Browser. By the way, I'm assuming that your table of information is showing all 5 companies, but only the first 3, AncestryDNA, 23andMe and MyHeritage DNA can be seen because your blog's right hand column obstructs what might be FamilyTreeDNA and Living DNA columns.

Blaine, well I can tell you this. For my first 3 Y-111 matches with Big Y results: Person 1, Y111 Genetic Distance 6, Big Y STR diffs: 9 of 435.

Big Y Non Matching Variants 21. So I note that 6 + 9 < 26, 7 + 6 < 22 and 7 + 7 < 21. Then would this mean that the 9 is really 20 steps, the 6 is really 15 steps and the 7 is really 14 steps?

Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
To add to what Skip said, I just got a group message from Jeff Wexler, who is a Y-DNA expert for the Ashkenazi Levites group. He said the following: "The column provides information concerning differences between men and their matches on markers 112 through 561, along the same lines as the information included in the "Genetic Distances" column on the same page for markers 1 through 111. The information is presented in the format "X of Y," where "X" indicates the number of steps by which men and each of their Big Y-tested matches differ on markers 112 through 561 and "Y" indicates the total number of STRs on markers 112 through 561 on which both men have tested. The reason that "Y" is necessary is that the next generation sequencing used by Big Y only rarely reports results on all 450 markers on markers 112 through 561; the reason that Big Y-500 has that name is that FTDNA is promising to report results for at least 500 markers -- the first 111 markers and at least 389 markers on markers 112 through 561. With a few exceptions the STRs on markers 112 through 561 mutate quite slowly; as a result, men in the same subcluster who share one or more deviations from the mode on markers 112 through 561 may be more closely related to each other than men in the subcluster who don't share that deviation."

So why then, do my clusters only use 8 people and exclude 1 who is not in a cluster? That's only 9 people. So then I opened it all the way up and went 9 to 600 cM (to include a 1st cousin at 411 cM) but it only went up to 11 people?

They would need a really good business reason to justify that.

Sorry Adina to have hijacked your post. Yes, I realized you were asking of other populations, but the 23 cM just hit me and I had to ask. I'm afraid I haven't seen articles on endogamy in non-Jewish populations that mentioned using longest segments.
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
Thanks. I see that ISOGG Endogamy article uses 23 cM referenced from a RootsTech message by Kitty Cooper on sticky segments that unfortunately is no longer accessible. However, on Kitty's website, I do find her reference to 23 cM in an interesting article that might have some good insights into endogamous Jewish research. She says that: "An experienced Israeli researcher told me to ignore anyone without at least one long segment match of 23 cM" so the source of that for now will remain unknown. https://blog.kittycooper.com/2014/11/using-ashkenazi-jewish-dna-to-find-family/ None-the-less, I personally disagree with picking a limit at all. Yes, longer segments imply closer matches (sometimes). And working from longest to shortest does give you a methodology - but I think it's tedious to work on them one at a time. Better in my opinion is to attempt DNA Painting and also to use the Leeds technique. The latter does an amazingly good job (at least for me on my Ashkenazi ancestry) to split my four grandparents families out. That's because the cM of closer relationships up to 3rd cousins are not affected that much by endogamy which is an important concept to know.
Louis Kessler commented on Adina Newman's post.
Group: Genetic Genealogy Tips & Techniques
Where did you get the accurate looking 23 cM number? Yes, you want larger segments but I don't think you can be so precise as to say 23 cM instead of 25 cM or even 20 or 30 cM.

Sharing half your individual segment matches, yes. But you total the individual segments to get the people you match to. So if there's a person you share 4 segments with, then your sibling should on average also share 4 with, and on average, two of those would be in common. So there should be a better than 50% chance of your sibling also being a match to someone if you are.
Louis Kessler commented on Matthew Sturgess's post.
Group: GEDmatch.com User Group
There can be matches by chance at both the start and end of any match, and actual matches may be smaller than the numbers indicate. So with match information like this, it's best not to assume small overlaps are real without verification. Yes, 458 SNPs isn't a lot, but you have verified that segments 8 and 9 match on that small overlap. Do the same with all the other people (lines 7, 10, 11, 12) and see if they too match both of the people on lines 8 and 9. Triangulations should mean everyone matches everyone over the segment. Take anyone out of the Triangulation Group who don't match all the others.

The Ashkenazi in Eastern Europe only started using surnames in the early to mid 1800s. So our Y matches have a wide variety of different surnames. We can't use Y-DNA like for the main purpose non-Jewish people use it, which is to see if suspected relatives with the same surnames are from a branch of our paternal line or not. If your dad is Cohanim or Levite, they would love you to have him do the test, as there are projects for those. I'm Levite and I've taken 111 and Big-Y 500.

Although the cumulative curve looks smooth, using that to determine the "slope" is nowhere near accurate enough to give you good cM estimates. The small graph at the bottom of your diagram contains the slope values that you need to use. They are quite erratic and it is important that you follow them. Otherwise, everything from 2 to 5 cM on your diagram will get a value of about 5 cM/Mb when in reality different segments in that range will vary from 0 to 15 cM/Mb. You might do a reasonable job on the 7 Mb to 15 Mb region, but you'll be way off in places between 17 Mb and 22 Mb. But try it if you want. I'm always one to learn by trying. p.s. It's not always easy to fit a polynomial well to a curve either.

I don't think smoothing to a curve is the right thing to do. There are small regions that have very high cM/bp ratios and others that are very low or even zero. If you smooth, you lose that. You should instead do a binary lookup of your original points and from the bounding bp's, interpolate to get the cM value. If you want more points for the Marey Map, you can get the data from: http://lbbe-shiny.univ-lyon1.fr/MareyMapOnline/ Select dataset "Homo Sapiens Mean" and then click on Step 2: Data Curation, and at the bottom of that page click the Save button.

Hi Kevin, I downloaded your program and instructions to my Windows machine. Found the first problem you should correct.

You should call the Windows API function SHGetKnownFolderPath with the parameter FOLDERID_Documents. That would properly tell you that my documents folder is D:\Documents on my machine.

I suspect part of the reason is that Lazarus only includes SNPs it can phase, and does not add no-calls. If it did, those would appear as matches and the Lazarus numbers would be what they should be. I can't believe that the MapS phasing can be this perfect, so I suspect MapS is adding no-calls. If that is the case, then this is an unfair comparison.

Tim, GEDmatch Genesis are still tweaking their algorithm and working on better match methods between company data. They have recently added to their One-To-Many(Proto) report an overlap column with color coding to indicate people you match to with less than 100,000 overlapping SNPs so as to warn you that their matches may be less precise, and they're working on their new Q-Matching tool to provide more accurate comparisons. Segments over 20 cM with only 500 SNPs is low density and is what you'd average with 85,000 overlap. So I get your point that the SNP count in the match is important. Maybe 15 cM is an upper limit and everything above that is almost always IBD when you have nearly full 700,000 overlap between the testers. Very interesting!

I doubt they would have a chromosome browser, but they say in the article they have an API, so matching data may be available for 3rd party tools. The price is 499 Chinese Yuan which is about $73 USD.

Group: GEDmatch.com User Group
Hey everybody! I found the problem. GEDmatch Genesis has two One-To-Many Comparison Results. The second one has (Proto) written in red, obviously meaning it was a prototype or experimental. (It actually has 3, with one in Tier 1 Utilities, but that one does not give overlaps) I ran the first One-To-Many Comparison and compiled the results for this post and it had the strange results that I displayed with my All 5 having fewer overlaps than my 23andMe only kit. I never expected that the One-To-Many Prototype would give different overlap numbers, but it does. And the numbers it gives appear to be correct, with my All 5 kit always having at least as many overlaps as my 23andMe kit in all cases. The non-prototype gives matches up to 7.5 generations but the prototype only gives the first 3,000 matches. Here's my results with the Prototype run. So basically the overlaps in the non-prototype run appear to be wrong and the prototype run appear to be correct. Thanks for all your input. You gave me ideas that helped me find what the issue was. Now I'll continue to analyze the improvement in matching with a combined kit over a single kit, which I'll post on my blog when it's ready.

Yup. The Diagnostics give me the same thing. My 23andMe kit is on the left. My All 5 kit is on the right and my merged All 5 has 2 to 3 times as many SNPs as my 23andMe kit. So shouldn't my All 5 file always have more overlap than my 23andMe kit?
Louis Kessler replied to Renae Smith Crowe's comment.
Group: GEDmatch.com User Group
It's not fully described anywhere, but logically it should be the number of SNPs that are in common between the two kits being compared. Different DNA tests may not have enough SNPs in common to give reliable matches, so the overlap can be an indicator of how good the match information might be. At least that's what I'm assuming in my question. If I'm wrong about this and it's something else, then that could explain the numbers I'm observing.
Louis Kessler replied to Krister Sjödin's comment.

Thanks, Ann! Yes, that would explain why the overlaps are lower than the number of SNPs in common. So that puts me at ease on that point.

Good theory, but then why would my 23andMe kit match be a 100% match with my All 5 kit? Maybe there is a limit on raw data files of around 700,000, but Genesis would then be having to be throwing away every 2nd one for everything else, my 1 to many matches, my 1 to 1 matches to work.
Louis Kessler replied to Drew Smith's comment.

My only thoughts, Drew, are that either my file is not exactly the way Genesis expects (but it's not reporting any problems), or there is something not quite obvious about Genesis' overlap calculation. You'd think, for example, that my 23andMe kit, produced direction from my 23andMe v5 raw data file should overlap about 630,000 with every other 23andMe v5 kit, but the maximum was only 591,654. I'll send John Olson an email with my kit numbers, because if this is something not correct on Genesis' side, he'll want to fix it.

Group: Genetic Genealogy Tips & Techniques
Debbie, I don't understand why whole genome will help. The 700,000 SNPs each company determines are the ones that have the most human variation (or of medical interest). The other millions of SNPs have much less variation and the remaining 99.9% of base pairs between the SNPs tested are identical in all humans. Meanwhile by using matching segments, you can include only segments that triangulate with each other that form a Triangulation Group. Anything 7 cM or more in a TG is almost guaranteed to be IBD just as any single matching segment 15 cM or more is almost guaranteed to be IBD.
Louis Kessler replied to Debbie Cruwys Kennett's comment.

What if you take a segment match you have and neither parent does. Then find the people you match to on that segment. Then find the people each of your parents match to on that same segment. If one of your parents match most of the people you match with on that segment, then the trouble is in the parent match with you. This may be worth looking at for a few of your largest parent/child nonmatching segments.

Randy W Whited - The problem is that if you look at the raw data from our main DNA testing companies, you'll see their sample of 700,000 or so SNPs are spread out over each chromosome.

Debbie, of course Y-DNA only takes one path up through one line of our ancestors. Whereas every autosomal segment takes its own different path winding up through any one of our ancestral lines. We have thousands of paths to map/paint and research. It is so much more fun to research all lines at once than just one line.
Louis Kessler replied to Jim Bartlett's comment.
Group: Genetic Genealogy Tips & Techniques
Debbie Cruwys Kennett - Even if the segment is found in (especially) my entire endogamous population, for me it *only* comes from one path of ancestors, e.g. my father's mother's mother's mother's father's … etc. (I could get that same segment on my maternal side as well, so then it would be 2 paths, but just 2 paths). Because it is a path of ancestors up that it is coming from, it is not only useful, it is very useful. It doesn't matter if the whole Jewish population got that segment. Every single person got it from only 1 (or 2 paths). By matching their path with my path, we can find out how we're related. Might be 2 x 2 = 4 possible ways, but it's not insurmountable like a thousand different ways would be. And chromosome mapping works to provide the direction of that path.

I know how I'm related to exactly one of them, a known 2nd cousin who tested. The rest, I have no clue. (Okay, there is one I have a clue on, and I'm working on it). If you include the Distant cousins, I've got 2,538 pages, i.e. 126,894 people matching me 6 cM or more. If I go to my 126,894th match, we have 26 pages of shared matches.

I did the Big Y test a year ago to help out an Ashkenazi Jewish study of the Levite line, that was traditionally passed down through the males that biblically would have started with Levi, one of the sons of Jacob. Jeff Wexler and Meir Gover are leaders of the project. The study currently includes 561 people who have taken Y-DNA tests at FTDNA, and from those, 93 have taken a Big Y test, and more people are being included all the time. Interestingly, almost all of us have different surnames, because surnames weren't adopted by most of the Ashkenazi until the early 1800's. This study is much more involved than I have time for, so I'm happy and lucky that my Y line's research is actively advancing on its own. And if you're wondering, other than my uncle, there is no one else in the study who I can genealogically connect to, because our records in Eastern Europe only go back to the early to mid 1800's. https://sites.google.com/site/levitedna/home

Thank you, Ann, for mentioning Wilhelm HO's program. I just tried it now, twice in different orders. It does seem that when the same RSID is encountered, he retains the first value unless the first value is a no call, in which case he overwrites it. He also lists a position more than once when the RSID is different. That is nice because it retains all the RSID's in the file. But it is also not good because it leaves more than one entry at a position that may have different values. I don't know how 3rd parties (e.g. GEDmatch) handle more than one entry of a position and which value they'll use if they are different. But for the number of discrepancies I found between raw data files, I agree with you, it is not a big deal and his program does just fine. What I did differently is sort by position, and I merged readings at the same position from all files at once. If all their readings agreed (not including no-calls) then I'd set it to that value. If any differed, I'd set it to a no-call. I was thinking of using a majority rule, e.g. AC in three files AA in one and I'd use AC, but there were only a few hundred like that, so I decided to be conservative and just set it to a no call.

Does YSEQ do the whole genome? Or do they only do the Y and mt chromosomes? What they say on their Whole Genome Sequence page does not say anything about autosomal. Do we get 70 Mbp or 3000 Mbp back from them?
Louis Kessler replied to Debbie Parker Wayne's comment.

What!?! Yes, they then say: "But of course health related information is contained in the raw data and can be extracted from a third-party expert." That makes no sense at all putting those two completely contradictory statements together. If you can extract the data (even it takes an expert), then it contains medical relevant information and they should not have said the first statement. You would think a whole genome would have to contain the medical SNPs. They only way it wouldn't is if they are purposely left out. So again, why that first statement?

Thank you, Andrew. I didn't expect it to be in the recombination directory. There are a lot of different maps in there. I tried the ones in the directories "latest", 2008-03_rel22_B36 and 2005-06_16a_phaseI and in the rates directories under those, but none of them gives 6.03 cM when I do the difference between 140,186,312 and 136,555,163 on Chr 9. They all give something between 9 and 13 cM. Do you know which one of them Family Tree DNA might have used?
Louis Kessler commented on Jay Lenn's post.
Group: Jewish DNA for Genetic Genealogy and Family Research
JA Mendelsohn - Jennifer, she wasn't giving cM, but number of segments. From her data (if I copied it into my spreadsheet correctly) I total the matches with the Mother 126.32 cM (26 segments), the Daughter 92.5 cM (21 segments) and the Son 100.06 cM (27 segments). I couldn't help myself. The data provided was just too interesting. To analyze this, you have to sort by Chromosome, Start and End, and see which of the children's matches fall upon the mother's matches. This validates the children's matching segments as ones that have been passed down from the mother. This can be done even with small segments because it's like phasing the segments to the mother. The son has 8 segments totaling 36.98 cM that were passed from the mother. The daughter has 10 segments totaling 47.68 cM that were passed from the mother. That's 18 of the mother's 26 segments shown to be valid and some of the other 8 may have been valid as well, but just not passed down. I do note there were a lot of segments that either the son got (19) or the daughter got (11). Normally those would be considered false because they have to have come from a parent. But I notice that 12 of those segments of the Son and Daughter totaling 47.44 cM have exactly the same start and end positions. I would surmise the only way that could have occurred is if they came from the father. So yes, Jay, I think you have a match, not only with the mother at 126 cM, but likely also with the father (isn't endogamy wonderful) which due to that double children matches totaling about what the same as their mother matches total, is likely at about the same level, maybe 120 cM. The bad news is that as Jennifer says, with Jewish Genealogy, matches of 120 cM are very unlikely to be figured out. Likely, many of those matching segments came from different paths and you're talking about being 8th cousins or more a dozen different ways to both the Mother and the Father.
Louis Kessler replied to Philip Gammon's comment.
Group: Genetic Genealogy Tips & Techniques
Eva Dahlberg - There are many different mappings to go from base pairs to centimorgans. Each company uses a different one. Many of the mappings are available at Rutgers: http://compgen.rutgers.edu/rutgers_maps.shtml and there are maps for each build and subbuild (34, 35.1, 36, 37.2, 37.3) and you can get them raw or smoothed using either Haldane or Kosambi mappings. And it is also different when calculated for the paternal chromosome and the maternal chromosome. The maternal chromosome have more crossovers and generally higher cM values than the paternal chromosome does. A combined/averaged number is usually given. Hendrik Wendland's free MapsS Converter tool https://www.maps-phasing.com/ can convert between Build 36 and 37 for you, either Haldane or Kosambi, for paternal, maternal or average. For instance on Build 36, Chr 9 from 135,574,649 to 140,145,149 using his tool (Kosambi, average) is 15.91 cM (what GEDmatch gives), on Build 37 it gives 17.37 cM (what 23andMe gives). I don't believe Family Tree DNA uses Rutgers Maps, but uses data from the International HapMap project which is no longer available for download. https://www.familytreedna.com/learn/autosomal-ancestry/universal-dna-matching/determine-centimorgan-value-dna-segment/ so their centimorgan values will be different from all the others. For instance, in my Chromosome Browser Results file from Family Tree DNA, Chr 9 from 136,555,163 to 140,186,312 (the closest I have to the range above) is only listed as 6.03 cM, much lower than the 15.91 and 17.37 from the Rutgers maps and being a bit smaller than your segment, is representative of the 7-8 cM you mention in your comment.

Ross: No this technique is not perfect. And yes, segment data would be better. But when all you've got is limited Ancestry data about your matches, using the In Common With information is the best you can do. And this Leeds technique is an innovative way to make as much use of this information as possible. For some people, it will nicely separate out great-grandparent families. And for everybody, it will give you a way to visualize the In Common Withs and maybe give you good clues as to who might be in the same branch to allow you to research further. I sure like this technique a lot better than those connected graphs of matches that look like a hodge podge of pick-up sticks.

My 2C1R just matches one other person in my 2nd and 3rd cousins, and I didn't include the two of them in this example. I don't know the true relationship of the first match I used in the example. Ancestry says it is a 2nd cousin with 355 cM, but I'm pretty sure it has to be at least a 2C1R or 3C because I know all my 2nd cousins. I have attempted to contact this person but got nothing back. This person last logged in Apr 11. 2017. :-(
Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
I've come out with a few of the properties of the Leeds technique that I think are important to know. 1. With perfect data, using 2nd cousins will make up to 4 clusters for the 4 sets of great-grandparents. Using 3rd cousins will make up to 8 clusters for the 8 sets of great-great-grandparents. Using 1st cousins will make up to 2 clusters for the 2 sets of grandparents. Using parents or aunt/uncles/nephews/nieces/siblings/children will turn everything into just one cluster. 2. With perfect data, including a range of relatives in a cluster (e.g. a cluster of 2nd, 3rd and 4th cousins) will create the cluster at the closest cousin level (e.g. 2nd cousin). 3. Data is not perfect because: a. Ancestry's estimate of cousinship may not be correct. b. Once you get 2nd cousins once removed and further, there is a chance that even though they are true cousins, they do not share enough DNA from that common ancestor to be a match. c. People who have an additional match through a different common ancestor will cause overlaps in the clusters.

Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
Dana: Thank you for confirming that. In my example I did last night (earlier in this thread), I was merging when there was overlap with only one color. So that wasn't correct. I've redone it and added it to a reply to that comment. This picture is an example with some of my real Ancestry DNA In Common With data that shows how the ordering can give different results. The ICW table is shown first. The second table is what is created if the people get added in order: Person 1, 2, 5, 9 and 10.. In that, Cluster #4 causes 2 overlaps for Person 3 and Person 7. Cluster #4 gets created here because an earlier group didn't already include Person #9. The third table shows what happens if Person 3 and Person 1 happened to be exchanged and the people get added in the order: Person 3, 2, 5 and 10.. It is perfectly clean with no overlap. Person 9 has already been included in Cluster #1, so Person 9 does not create a new cluster in this case.
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
Dana explained in a comment below that I shouldn't merge matches. Above I had merged my clusters 6 and 7 into cluster 2 because they overlapped, cluster 4 into cluster 3, and cluster 5 into cluster 2 because the 2nd person had an In Common With the 2nd person in cluster 2. That's why my diagram above looked so good. Redoing it and doing it the correct way (with any overlap meaning a new column is created) gives me this new picture. But there are some really good independent groups that can be used to hypothesize from the same great-great grandparent group.

Blaine, If the clusters are clean and distinct, then you're right, order won't make a difference. But if the next unassigned person is someone who overlaps two groups, I believe it could make a big difference. I'll see if I can put an example together. Re number 2, you're right. Sorry I said it that way. I just didn't know what to do at that point when I read Dana's instructions.
Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
I still think this is really great. But I've discovered two issues: 1. You look at your shared matches with Person A, and Persons B, C and D are in there. If you then look at your shared matches with Person B, then Person A will be in there for sure, but persons C and D may or may not, and there may be other people, say E and F who B doesn't share with. What this means is that the order is important. If you checked Person C before checking Person B, you can easily get a different result. 2. Dana's instructions should include what to do when the next unassigned match has some shared matches that have already been assigned. There's two possibilities: (1) they are all the same color, in which case I presume you can assign this person and any new matches that same color. (2) they are of more than one color (e.g. As Dana shows in Column C of her "Some Overlap" section of her instructions.). It seems Dana wants us to assign a new color for these, but she doesn't say. Another possible reason for this might be that the person is closely related to one group through one branch of their family and the other group through another branch and actually are related to you through both sets of great-grandparents.

Wow! I am truly amazed! I never expected this to work for me, with a totally Ashkenazi family on all sides (endogamy times 4). But using my Ancestry data, it gives me 3 sides (great-grandparents) and there's only one person that matches into two clusters. I do have three people unclustered, i.e. were not in common with anyone else, marked in green. Unfortunately, I only know how I'm related to the first person on this list, a second cousin once removed. So I presume that set of great-grandparents would be the blue color. I'll try this as well with my FTDNA, 23andMe, MyHeritage and GEDmatch matches where I have a few tested relatives I know the relationship to. I'll see if I can combine the results. Then maybe I'll see if I can add 4th cousins and determine 8 groups (sets of great-great-grandparents). I can do this as well for my uncle and see if I can combine everything together.

For the 23andMe match, when entering the percentage of shared DNA as "0.12", it comes out as: "[Percentage of Shared DNA (omit %)(Example: 0.12)]%"

Saying: "predicted 2nd cousin sharing 12% across 8 segments to John Smith" reads a bit awkwardly because of the "to" following the "segments". It might read better as: "predicted 2nd cousin to John Smith sharing 12% across 8 segments". When trying the AncestryDNA match, it gives "with" instead of "to". This should probably be consistent between the companies, either as "to" or "with".

For the AncestryDNA match (and maybe others), if the access date is not given, then ": accessed )" is still displayed.

https://www.ancestry.com/dna/tests/ is not a valid url, even when logged in. Should non-publicly available urls that will not work for other people be included at all? After all, isn't the purpose of the url so that other people can check the data?

Yes. The maternal aunt match on chr 6 defines your husband's maternal segment. Everyone significantly overlapping on that segment that match your aunt and each other form your maternal triangulation group (TG) on that segment. Anyone who doesn't match the maternal TG must either be in the paternal TG or be a false (by chance) match. One caveat: if the maternal aunt is also related on the paternal side as well, that could be a paternal segment. Also, smaller matches under 15 cM with the aunt could be false.

For me, I only see 98% European Jewish and 2% Germanic Europe (which I think is wrong) and I don't have any Low Confidence Regions at all. When I click on the two percentages I get 93%-100% European Jewish and 0%-4% Germanic Europe. I believe my correct proportion is 100% and 0%, so the ranges are correct.

Yes, of course. But I do think all the companies, Ancestry included, want to imply that their estimates are accurate and that is what they show (and what Ancestry shows first), rather than showing the range first or only. Providing the range front and center would result in fewer people jumping to the wrong conclusions, e.g. People trying to find their 1.4% native ancestry when it's really 0% to 5% with a high likelihood of 0%.

So yes they do, but few people realize that and click and I've never seen anyone report the range, only the average giving the perceived accuracy. What they should do on the first screen is show the range and clicking then could give you the mean and maybe other statistical properties. That would be much better! We've got to get people reporting the ranges.
Louis Kessler replied to Drew Smith's comment.
Group: Genetic Genealogy Tips & Techniques
There is nothing at all wrong with them taking 40 samples of your DNA and finding the ethnicity of each and then averaging the results. The statistical reason for doing this is to determine the variance of the estimate, but they are throwing this information away and not telling you it. In my opinion, the problem is not that a second estimate will be different from the first estimate. What all the companies are doing wrong are reporting the percentages so that they look accurate, e.g. as 81.2% or 81% when they should be reported with the variance that their sample is determining, e.g.: ethnicity is between 75% and 90%. A value of 3.1% should be reported as: between 0% and 10%.

Thinking about this some more, the above is a subset of a notation I came up with a couple of years ago but never put into use. Back then, I was concerned about the abbreviations M and F being ambiguous and being English-centric, so I picked the universally understood sex-chromosomes X and Y to represent female and male and used capitals for parents and lower case x and y for children. In that notation, I put the MRCA in parenthesis so you could distinguish between full and half relations, e.g. (YX) versus (Y ) or (X). So my above example could be: YXXYXYY instead of FMMFMFF. Which do you like better? http://www.beholdgenealogy.com/blog/?p=1727

Personally, I have one refinement to overall sequential numbering. And that is to place everything by who or where I got it and number sequentially from within that. Everything from my parents is together. Everything from one of my 3rd cousins is together. Everything from my Provincial archives is together. Everything from Ancestry is together. Next time I'm going to talk to my third cousin, I review the material he gave me and I know what he has and hasn't provided. Next time I go to the Archives, I know what I have and have not obtained. For Ancestry, I do subdivide by document type and person so I can easily see what I've already found.

The advantage that I like is that all items you obtain at one time from one place will be together so you can browse through what you got there and then, which oftentimes is very important.

Okay. I can accept the idea that "triangulation" is the process of finding matching people or matching segments in order to find an MRCA. But that is very restrictive and doesn't include forming triangulation groups to help determine maternal/paternal sides and map your chromosomes, or to filter out many false matches. Yes, the ultimate goal is always to find out how you and each of your matches are related, and triangulation is a tool that can help you in different ways towards that goal.
Louis Kessler replied to his own comment.

"triangulation is the term used to describe the process of reviewing the pedigree charts of people who match on the same IBD autosomal DNA segment to see if a common ancestor can be found." Triangulation is not reviewing pedigree charts. It is comparing matches (#2) or segments (#3).

If you are just mapping the matches of one person, then segments under 15 cM and especially segments under 10 cM could be made up of a lot of by chance matches. You'll need to see if they match each other and then put them into up to 2 triangulation groups, one paternal and one maternal. But even then for the ones that triangulate, an overlap of 5 cM could be from a common ancestor 10 to 20 generations back. Do you recognize any names at all from the 95 people or have any surnames or places of origin in common between them? I'd suggest you try the same thing with GEDmatch data, because there you can verify the triangulations by doing 1 to 1 compares.

I was surprised by Living DNA asking just for grandparents, for exactly Tommy's case. They say they are trying to find people whose 4 grandparents are born within (I can't remember the exact amount but something like) 50 miles of each other, possibly to use those people as DNA representing that locality. So you may have 4 grandparents all born in Chicago whose parents come from 8 different countries, and then your DNA will represent Chicago. However they are doing some really innovative stuff with locational DNA, so I guess they must have found that 4 grandparents works well for them. We'll soon see once they make their One-Family results available, currently scheduled for August. In my case, my four grandparents were all born within 100 miles of each other in northeast Romania and southwest Ukraine, but they didn't make the criteria and likely my DNA won't be used for that locality.

Jordan - Guess what!? I couldn't draw it. That's because Denise can only get one of her segments from her mother. If Denise matches her aunt Francine on the same segment, then she and Denise have the same segment there. If Denise matches Bonnie on that segment, then Francine would also have to match Bonnie on that segment. If Denise is matching Bonnie on her other segment, then it would have to be from her father's line. So the rule would be, if you match someone on a segment and you match your aunt/uncle there, but your aunt/uncle doesn't match that person as well, then that person has to be matching with your parent who is not a sibling of your aunt/uncle. And your original conjecture would be correct. Working these out is a real logistics problem. We need a software program to help us with this.

Louis Kessler replied to Jennifer Leigh Eckman's comment.
Group: Genetic Genealogy Tips & Techniques
Jennifer - Blaine's chart is correct if Grandmother and Francine are fully identical and is correct as to how DNA can work. But I think your situation is not as Blaine drew. In your case Denise matches Bonnie through Mom. That may have come through Mom's father, or through Grandmother. Your question is whether or not it could have come through Grandmother if Francine doesn't match Bonnie. The answer is yes, Both Grandmother and Francine got one of their segments from their mother's pair and one from their father's pair. Let's say the segment related to Bonnie was their father (Great-Grandfather in Blaine's diagram). Great-Grandfather has two segments, one from each of his parents. If his father was related to Bonnie, then he passed that segment down to Grandmother and he passed the other one (from his mother) down to Francine. Therefore, Francine is not related to Bonnie, but Grandmother, Mom and Denise are AND it is through Denise's maternal Grandmother's side. And remember, I'm just showing it is possible for it to be Grandmother's side. it is of course still very possible for the connection to be through her Mom's father. You just can't discount the possibility which was your question.

Leah LaPerle Larkin - I agree with you that starting with one Triangulation Group cannot prove a specific MRCA, especially if it's made up of relatives past 3rd cousins. It could always be someone else. But doing it the way Jim Bartlett teaches, with Triangulation Groups you can assign segment matches first to paternal or maternal side, and then divide those into smaller segments for grandparents, and continue "Walking the Ancestor Back" generation by generation. Doing it this way with enough data for each step/segment is as close to proof as you can get. You may or may not be able to get back far enough to that specific Triangulation Group you were interested in, but if you do, you can be pretty confident that you've followed each ancestor up one by one to get to the MRCA.

If you determine from VP that a particular segment you got is from your father's father on one strand and your mother's mother on the other, and your sibling got the same segment from your father's mother on one strand and your mother's father on the other, and the third got hers from one or the other, you should be able to phase the actual alleles of your parents, your father's into his two parents, and your mother into her two. That appears to me to be phasing the parents. What am I not getting?
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
Yes, Blaine. If the parents are phased, then simply do a match of a child to the 2 phased father segments (grandfather 1 and grandmother 4) and to the 2 phased mother segments (grandfather 2 and grandmother 2). The child will half match to one of the father's segments and half match to one of the mother's segments up until a crossover when one of the "grandparents" will change. I think a program would be able to determine this exactly with 2 phased parents and any child. And it can return the child segmented into his four grandparents, just like Visual Phasing does.
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
By the 4 grandparents, I'm referring to the 2 phased chromosomes of the two parents. Isn't that what Visual Phasing is determining?
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
But if the parents are both phased, can't a program just compare the child's DNA to the four grandparents, and shouldn't that give the two grandparents that half match on every segment? I think it results in the same thing.
Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
Blaine, wouldn't both parents have to be phased to generate random siblings? And if they're phased, don't you already have the grandparents?

People can match on multiple lines. And different segments can match on different lines. But one paternal or maternal segment only comes from one common ancestor on one line.
Louis Kessler replied to Jennifer Mendelsohn's comment.
Group: Jewish DNA for Genetic Genealogy and Family Research
Those are all small segment matches under 10 cM. Any match under 15cM could be a match by chance, flipping between your maternal and paternal chromosome to match either of theirs. Having one of your parents also matching helps verify a match. In this case, a small match by a child with neither parent matching is almost for sure a match by chance and should be ignored. Because both you and your sister share with that relative, I suspect you both are fully identical on that segment, I.e. you got the same segment from your mother and the same segment from your father that your sister did. So you both match that relative by chance in the same way.

Paula, Blaine: My cousin got back to me. Their niece shares only 0.72% with me, so that's why she's not on my list because my 1121 DNA relatives only go down to 0.82%. According to Jonny Perl's DNA Painter interactive version of Blaine's Shared cM Project using Leah Larkin's probabilities, 0.72% is 54 cM and there's close to a 9% chance that it might come from the 2C1R grouping, so this is quite possible.

So unless I lost some, then I have only 2 new matches since I signed up and what appears to be 30 that changed from non-sharing to sharing (including the 4 non-sharing people that accepted my request to share) The two most recent matches were 0.93% and 0.89% although the 3rd on my list when I sort by most recent is 0.85%. My smallest amount of any match is 0.82%. I don't think they ever gave me 2000 matches.

Group: Genetic Genealogy Tips & Techniques
At 23andMe, I have two genealogically known second cousins who are brothers who share 2.13% (10 segments) and 2.00% (8 segments) with me. They are my 2nd and 3rd closest matches out of my 1121 DNA Relatives at 23andMe. They have a niece, another full brother's daughter who tested there. She is definitely their full niece since they match her at 23.3% (42 segments) and 23.1% (43 segments). So this niece is my 2nd cousin, once removed. Yet like Leah's relative, their niece does not show up on my match list. My 1121 relatives in my DNA Relatives include 649 with Open Sharing and the rest without. Their niece is not open sharing, but is not in my list of matches. I'm not at that 2000 limit that you're talking about, which I feel is strange since I'm Ashkenazi and would expect large numbers of matches. The lowest % shared of my 1121 matches is 0.82%. I suppose their niece could have been just below that for me, but my goodness, this is a 2nd cousin once removed and not sharing with a known relative of that relationship is a very rare thing, especially when I've got endogamy helping me out inflating our shared DNA. So like Leah, I'm wondering why this person is not in my list of matches.

Group: Genetic Genealogy Tips & Techniques
Jim Bartlett What a great idea! You prompted me to take Blaine's Dad: F.B. and Mom S.B. and do some analysis.(Fortunately, or unfortunately, depending on your point of view, GEDmatch makes it easy to find these). At 1/300, F.B. and S.B. share 105 segments, largest 3.8 cM. I expect these are likely all false, so Blaine shouldn't worry too much about his parents being related. I share 88 segments with F.B., largest 6.3 cM My uncle shares 77 segments with F.B., largest 5.2 cM My uncle and I triangulate with F.B. on only 3 segments, largest 2.9 cM I share 78 segments with S.B., largest 4.9 cM. My uncle shares 77 segments with S.B., largest 4.0 cM My uncle and I triangulate with S.B. on 3 segments, largest 3.1 cM None of the 7 triangulations of me, my uncle and Blaine, overlap any of the 3 triangulations of me, my uncle and F.B. or any of the 3 triangulations of me, my uncle and S.B. So no triangulation group can be formed with any group of 4 people. Thus, all small segments have been eliminated by doing the triangulation on both sides. I think Jim has shown and I have also observed that the more matches you add to a triangulation group, the more reliable it becomes. Even small segments that randomly match one or two people will soon be found to not match someone in the group and thus be eliminated. Thanks, Blaine. I enjoyed doing and added to my knowledge with this exercise.
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
Blaine T. Bettinger - Of course phasing and triangulation and parental filtering are not 100% effective. But they do cut down a large percentage of false matches making it easier to find the ones that might be real. They also allow you to be confident with segments down to at least 7 cM. True, that segments this small could be too distant to find an MRCA, but they could provide important leads especially when forming your triangulation groups on that segment. And vice-versa, knowing the ancestor who the triangulation group maps to may allow you to focus your search to see if you can connect the others. Sometimes the match is small not because it is distant, but because it had an unfortunate crossover that cut off its bigger portion. None-the-less, I agree with your concept that you should start with larger matches and to not blindly accept small segments as meaningful. But when used properly, the small segments may turn out to be useful.

Obviously, small matches without any filtering are going to be false. Running myself against you, Blaine, at 1/300, I've got 75 matches with largest 4.9 cM. When I run my uncle against you, he's got 84 matches with largest 5.0 cM. But if I compare my matches to you with my uncle's matches to you, which is effectively triangulating with you, all of a sudden there are only 7 triangulating matches left, and the largest is only 2.4 cM. I had 14 matches with you between 2.5 cM and 4.9 cM that all were eliminated through triangulation. My uncle had 16 matches with you between 2.5 cM and 5.0 cM that all were eliminated by triangulation. Triangulation also eliminated all but 7 of my 61 matches between 1.0 and 2.4 cM with you and all but 7 of my uncle's 68 matches between 1.0 and 2.4 cM with you. In other words, triangulation for me eliminated 100% of the false matches 2.5 cM and larger, and it eliminated 89% of the false matches between 1.0 and 2.4 cM.

Debbie Cruwys Kennett The companies are filtering out the thousands of people who match us on 1, 2, or a few segments that are no more than 6 cM long. Speed and Balding include those. Also, companies are including false chance matches up to 20 cM with a very large number of false small matches. Speed and Balding are not. Then there's the fixed 50,000 population they use which after 50 generations somehow still has individuals that somehow have matches 30 generations apart!? It's just so different from the segment match data the companies give us that I can't see it being even remotely applicable to genetic genealogy. Maybe the shape of the curves is good to know. But then it's their specific results being quoted verbatim, without any caveats which are misleading.
Louis Kessler replied to his own comment.
Group: Genetic Genealogy Tips & Techniques
Debbie Cruwys Kennett Well, yes. But as I've stated before, I think it is inappropriate to relate Speed and Balding's results to what we see in our matches, mainly because what we see are filtered by the DNA companies by their minimum match criteria which will eliminate almost all people who only have distant small segments in common. The expected amount of DNA we share with people beyond 15 generations from us will seldom make it through this filtering and thus won't be in the segments of our matches. But Speed and Balding include all segments unfiltered, and they did it for a different purpose, specifically to find in their simulation individuals unrelated for a disease study. Their study is excellent for that purpose. So their population geneticist peers naturally and correctly accepted the paper and those findings. My objection is that some genetic genealogist, I don't know who, happened to find their paper and blindly apply their results to his/her segment matches. Then everyone followed suit and the use of their Figure for segment to genetic distance made it into the ISOGG Wiki. This action of inappropriately applying a result is what does not and did not get peer reviewed, but simply gets published and virally repeated as fact like an incorrect ancestor in an online family tree, and is thus so hard to correct or even get anyone to realize. It is the inapplicability of their result to our filtered segment matches that I'm trying to point out and dispute to the genetic genealogy community.

Blaine T. Bettinger - It seems we may have to set different "safe" cM criteria for different companies. The practises of population-based phasing, imputation and stitching do appear to be making matching worse, not better. Family Tree DNA, at least currently, does not employ any of those techniques. A study I did a year ago with Family Tree DNA sets of child/parents found no false segments at 15 cM or more and only 5% at 10 cM.

Louis Kessler replied to Jim Bartlett's comment.
I agree that MyHeritage DNA is likely multiplying their inaccuracies more than the other companies. They are not just doing imputation, but they are also doing non-exact phasing and stitching. I think the latter (the stitching) is what's making some of the matches longer as you are observing. This recent post by MyHeritage DNA describes in detail how they now do their matching: https://blog.myheritage.com/2018/01/major-updates-and-improvements-to-myheritage-dna-matching/
Louis Kessler replied to his own comment.
Jim Bartlett - I agree. Using small segments to "prove" a relationship is wrong. But I think the opposite might be possible. If you know a relationship because of genealogy and large segments, then many of the small segments from that match may be useable. They could be random but also could be small because of an unfortunate crossover location. That's why I don't think we should simply throw all small segments away, and we need a study to determine the probability that small segments with known relatives are IBD.
Louis Kessler replied to Jonny Perl's comment.
Jonny Perl - If you know the segment should triangulate, then if MyHeritage DNA is actually checking that each person's segment is matching each of the other person's segment at each overlap, then you should be getting the results you expect.

But we do not know what they are really doing. I suspect they may not be checking the actual segment of each person against the other because it might be too computationally expensive and it might (especially for small segments) show a triangulation when there is none.

What I think they are likely doing instead is using each person's predefined segment match list and from those making sure that person A overlaps with B, C, D and E at that location, and that person B overlaps with C, D and E, person C with D and E, and person D with E at that location.

This could exclude some true triangulations because if Person A doesn't have enough total cM to match Person D, then Person D will not be in Person A's match list and they will conclude "no triangulation" between all the people, even though those people may actually match on that particular segment.

Do you know if the people you say "definitely should have triangulated" all match each other on enough cM to be considered a match. Quite possibly not, because any 3rd cousins or further might not share enough DNA to be considered a DNA match. So some combinations of your group of 5 might not match.

Comparing match lists would be a reasonable and conservative thing for MyHeritage DNA to have chosen to do, because if not everybody in a group matches each other, then by default it's easier to say they don't triangulate anywhere than to argue that they do on a few segments.
Louis Kessler replied to his own comment.
Of course, the bigger problem with small segments, even if they are IBD, is that they'd often be from an MRCA too many generations back to be genealogically traceable in most people's trees. And even if people have trees that go 15 generations back, genealogists will be tempted to pick that one common ancestor 15 generations back when it would most likely be someone else. That more than anything is the reason I feel it is right to concentrate on the larger segments.
Louis Kessler replied to his own comment.
The real nice thing though, is that we have 3 great tools that all help reduce the number of false segments: Phasing, Parental filtering, and Triangulation. I know we both agreed on a Facebook post long ago that it would be wonderful to do a study that compared the three against each other, and even using them in pairs or all together.

For example, if you could get reliably phased data and then triangulate with the phased data, I would wager you might be able to get down to 2 cM or so where nothing larger would be by chance.
Louis Kessler replied to his own comment.
... and I'd love to do a study to compare triangulation of small segments with non-triangulating small segments. But I have no idea of how to get a dataset of 99.999% IBD segments that could then be matched with each other to test the hypotheses.
Louis Kessler replied to his own comment.
Blaine: I definitely agree with you that people misunderstand triangulation. If a segment is IBD then it must triangulate, but not necessarily the other way around. e.g. Person A and B may be IBD but person C may match randomly to both of them. (Usually that would have to be matching randomly to the IBD segment which is tougher than matching to either segment). Or (as you pointed out to me a year ago), they could match on opposite parents: A1=B1, B2=C1, C2=A2, which triangulates but is not IBD (although any or all of the 3 matches may be).
Louis Kessler commented on Blaine T. Bettinger's photo.
Blaine: Regarding your "NO evidence that triangulation increases the probability that a segment is real."

Well, we pretty well know that a (non-triangulating) segment match with someone else is almost always real if it's at least 15 cM, but it might be false if it's less than 15 cM and the probability of it being false increases the smaller you go.

And I agree with Jim Bartlett's conclusion that a triangulating segment match with two other people is almost always real if it's at least 7 cM, but it might be false if it's less than 7 cM and the probability of it being false increases the smaller you go.

Taking that, then triangulation definitely increases the probability that a segment between 7 cM and 15 cM is real since (according to JB) all triangulating segments in that range would be real.

I would say this can be carried backwards to smaller segments as well and the reason is that with triangulation, you now need not just one agreement at each allele, but 3 agreements (A=B, A=C, B=C). If you had a 90% chance that a segment would randomly match between two people (i.e. 10% chance it is real), then for 3 people to triangulate, there would be a 90% x 90% x 90% = 72.9% chance of randomly matching, meaning a 27% chance that it is real. So for this example, the likelihood of this segment being real is almost 3 times greater if it triangulates.

Thank you. I think I see what you're getting at then. If you have a common ancestor that are on the mt (complete maternal) lines of two people, then because the segment is being passed down maternally generation to generation, the higher number of recombinations should be used to determine the cM due to more chance it happening. The larger cM values for two all-female-line cousins are thus reflective that the common ancestor is likely closer than they would be for two all-male-line cousins. All other lines would be somewhere in-between the two, depending on the ratio of mothers to fathers you go through to get to the common ancestor.
Louis Kessler commented on Hendrik Wendland's post.
Group: The Visual Phasing Working Group
I'm not sure at all why the female-female and male-male cM values are useful. I do understand that the mother's chromosomes have more recombinations than the father's when building the chromosomes they pass to the child. But the child always gets one of each pair from each of parent, resulting in them averaging out in every person. So when you're comparing a match between a person and a cousin, even if both are male or both are female, their own individual cM values would be average. When either has a child, yes they will have more recombinations if female and less if male, but their chromosomes will always be paired with chromosome of their partner which will average out the cM in their child as well. Therefore, even though I think it's an innovative idea to have included it, I don't see what the female-female and male-male cM calculations could be used for. p.s. The link you give above for Kosambi/Haldane seems to be timing out, but it is available on Archive.org: https://web.archive.org/web/20170602001740/http://www.ias.ac.in/article/fulltext/reso/016/06/0540-0550

Group: Genetic Genealogy Tips & Techniques
64 was just an example. The theoretical number is one per pair of furthest back ancestral couples that you inherit data from. You can have just one person on each of those descendant lines, because if you have 2 or more they will be related to each other. And I was thinking in terms of truly related, not DNA related. Statistically, with regards to shared DNA, the number at any generational level can be more than that, because once you get to 3rd cousins and further, there is a statistical chance that they share no DNA between them. This is probably what was really asked. So you would ultimately need everybody being no closer than 4th cousins with anyone else. Trying to illustrate this more clearly: Let's say you have 10,000 matches. Take 1 on your dad's side and 1 on your Mom's side. Well they'll have some people that they both match, but there should be lots of people on one side that don't match lots of people on the other side. Now take one of those matches on your dad's dad's side, one on your dad's mom's side, one on your mom's dad's side and one on your mom's mom's side. Since they're on different sides, each might not match anyone in the other 3 groups, and your number would be 4. But you need completely independent sets of great-grandparents, not related to each other. The chance of this happening becomes more remote each generation back. Like the birthday problem (how many people do you need before 2 have the same birthday), as you add another person to the pot, the chances grow greatly of having a match until you have almost certainty of 2 people having the same birthday when you have 30 people in the room. My guess would that you would be unable to find 12 people you match to where one of them doesn't match one of the others.
Louis Kessler commented on Paul Veltman's post.
Group: Genetic Genealogy Tips & Techniques
Theoretically, if you have 64 pairs of great-great-great-great-great grandparents who passed DNA down to you, then you can without endogamy or marriage between lines, have one tester from each line not related to anyone in any other line. So in this case 64 people not sharing a common match. So the theoretical answer is one per pair of furthest back ancestors that you're going back to taking into account pedigree collapse which will ultimately limit the maximum.

They have is in fact implemented true triangulation, but as Paula says, they all have to match each other. Remember there are four possibilities for each person matching on the same segment.

+Blaine T. Bettinger - My 10,000 segments in my GEDmatch file are from 4,468 different people. 1,687 of them only have 1 matching segment to me. The rest have between 2 and 11 matching segments with me, except for my uncle who has 62 matching segments with me. My uncle's area is the bottom left section where so many people are overlapping. The blobs all appear to be specific areas on specific chromosomes, e.g. the dark round one on the left edge are 22 people forming a 20 cM triangulation group on Chr 20. It is made up of people who only match that 1 segment with me. So it seems to me that blobbing is not due to endogamy, but instead is due to how many closely related testers you have. For example, if I had 2 siblings a parent 2 uncles and 3 first cousins tested on both parent's sides, then those people would have complete coverage and all the farther away people would match to a some of them and you'd have one big blog. But my only close tester is my uncle.

Hi Maureen: Long time since we were on the cruise. Tagging sounds like more work to me. I just like the idea of knowing exactly where to put something when I get it (everything I get together stays together) and not having to duplicate anything because it applies to different surnames.
Louis Kessler commented on his own post.
Group: The Organized Genealogist
I find it very interesting that it is so hard to find people who file by where they got something. Linda Debe: I understand why you might not think this is helpful. Here is my reasoning why I think it is. You have obtained quite a few things from a cousin, including letters, research, documents, etc. You now get some more material from your cousin. If all the material that you got from your cousin is together, you can compare and see what's new and what's changed. If your material from your cousin is not stored together, how can you talk to your cousin about what he's already given you and what he hasn't? You have done a whole number of searches on Ancestry by surname and place. You've downloaded lots of birth, marriage and death records for a number of people, along with census records and pictures and ship records. It is now two years later. You want to search Ancestry again to see what they've got now that's new. If you don't have a folder with everything you got from Ancestry, how would you compare the material you found before, especially since it may be under many different surnames or document types? You got a researcher to do some work for you. I hope you keep everything you got from the researcher together, or do you break it all up into pieces and not be able to determine what you got from them and what you need. Your cousin comes along and asks you for the material the researcher gave you. What do you do? And now let's get a little silly: You get a Family History book from the town your great-grandfather grew up in. You cut the book into pieces and put each clipping in the file folder of the surname it belongs to. Or on a similar note. You get a bunch of photo albums from your cousin. You take all the pictures out, throw away the ones that don't pertain to you, digitize the others, and file them under surname, duplicating them as many times as necessary for every surname. How do you retain any context of relationship or time order between the pictures if you do this? And the best one: Cemetery photos. Surely you file them by cemetery, and row and plot. Or do you split all of them up as well. My reasoning is that when I go back to an archive, an online site, or communicate to a cousin, the most important thing to me is to know what I've already got from them and then be able to determine what they now have that I need or may have missed before. I use my genealogy software to record the people, along with the facts and events in their life that are each verified by a source. The software will record the sources (where I can see if I have a duplicate - and sometimes they are different!) which then point to the file on my computer that is stored by where I got it. The where I got it is then part of the file path, e.g. d:/source - repositories/Saskatchewan Archives/document of death of Focsaner, Josub 1924, Lipton,pdf So I feel keeping everything together from one place is important. And by doing so, you retain context and the relationship of one thing to another, and it is easy to go back to where you got it and ask questions about it and update it as necessary.

Wow! Thank you Leah LaPerle Larkin! I've never heard of a homologue before. Would genetic genealogists (e.g. Blaine T. Bettinger) know what it is if I started using that term? Looking on the web for it, it does come up in Wikipedia under "Homologous chromosome" and is referred to with the spelling "homolog" rather than "homologue". Which spelling would be the more proper? Or would homolog be "American" and homologue be "British"? The ISOGG wiki refers to two homologous chromosomes, but never once calls a single a homolog or homologue.

Well, for example, if you had 3 other people who triangulated between 105 Mb and 117 Mb. and they also triangulated with Kelly in that region, then those 3 people and Kelly would form a new TG - but the original TG would stay the same including Kelly, who would be in both TGs.

Louis Kessler replied to his own comment.
Group: International Society of Genetic Genealogy (ISOGG)
Debbie Cruwys Kennett - It's easy to criticize someone and say what they are doing is flawed, and to religiously accept another person's result because those wrote a paper and used a simulation. I would not call statistical analysis using accepted input values from Speed and Balding and from ISOGG to be guesswork. Yes I could write a simulation, but every simulation is based on assumptions and is just a model of reality and is non-reproducable by others unless exact parameters are given. I don't believe Speed and Balding's 50 generations constrained to 10,000 people for all those generations reflects reality as much as it reflects an extremely endogamous population. And they make no attempt to eliminate segment matches that would be from people not in one's match list. With that level of endogamy, I'd expect hundreds of tiny segments for everyone. I think Speed and Balding's article is fantastic. I am simply peer-reviewing this one aspect of their article, Figure 2B, which everyone has unquestionably taken as gospel. I've presented different analyses that give different results. In the end, if you want to believe Speed and Balding is correct, then so be it. If you want to believe I'm correct, then fine. If it makes you question, and you want to analyze this yourself, all the better. But I did at least want to present my alternative view.
Louis Kessler commented on his own post.
Group: International Society of Genetic Genealogy (ISOGG)
Debbie Cruwys Kennett - Very simply, Speed and Balding presented Figure 2B which looked to me to overstate the G for segment lengths below 40 Mb that a person would see in their segment matches. I did some statistical analysis that I presented in my first article, giving the version of their Figure 2B that I came out with. The Ralph and Coop paper had cousin information that could be used to generate a third version of Figure 2B, so this article illustrated how I did that and presented that Figure, which agrees more with my result than with Speed and Balding's. I would be very happy if anyone else would tackle this issue and, either through simulation or statistical analysis, provide another view of this.

Yes, Debbie. I am now working with the help of your thoughts as well as those of Andrew Millard to try to statistically represent what Speed and Balding have simulated so as to better understand what their results represent. The constrained population is one thing (similar to a small version of Iceland over the past 50 generations or 1250 years). Also, since they go down to tiny amounts of DNA in their result, they may be considering any amount to be detectable. I'm in brainstorming mode and it may take me a few days to come up with something, especially since I'm now on my way to Houston for FTDNA's annual Conference.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Hmmm. Now I'm thinking that their 10,000 people may be more a model of extreme endogamy than anything else. After 12 generations or so, every person has to start pairing with someone they are related to. By generation 20, everyone will be related to everyone else in almost every way imaginable, and that continues for the next 30 generations. That may be the reason for segments seemingly being passed down an extreme number of generations.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Debbie Cruwys Kennett - Yes. Make that 9 cM (for FTDNA) and you are correct and I am mistaken on that point. Then it's got to be some other problem for the large segments, because clearly it is impossible for there to be more than 20% of the segments between 30 Mb and 40 Mb to be from > 20 generations back as Speed and Balding's Figure 2B shows.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Thank you Debbie. Doug Speed gave a nice response and I provided my assessment. It seems there was no reason for Speed and Balding to have needed to filter their results for the match requirements of people in one's DNA match list. Their studies didn't require it. My results include the adjustment required to make their data applicable for only the matches that meet FTDNA's requirements for being in one's match list.
Louis Kessler replied to Andrew Millard's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Andrew Millard - The mathematics don't allow it. As from my cousin table (correcting that it is 1 G off): You and someone share a specific segment. There are 8 first cousins at G=2 that you might share that segment through a grandparent. If that's not how it is shared, then there are 38 G=3 second cousins who you might share that segment through a great grandparent. Now that's 46 different people who are G=3 or less. If that's not how it is shared, then there are 190 G=4 third cousins who you might share that segment through a g2-grandparent. Now that's 236 different people who are G=4 or less. By the time you get to G=15, there are now a over billion people who are fourteenth cousins or less who you might share the segment with through a g-13 grandparent or closer. Now you start running out of possible people in the world to be cousins and the E(# of cousins) at a particular G can not continue growing forever and starts contracting. By G=20 you're up to 3 billion people in the world. Maybe I've continued the expansion of cousins at too fast a level, but that ratio of 5 that ISOGG table has for first 8 generations cannot continue and must be reduced in some way. Remember we are talking about a physical segment. It does not care if a person is a 8th cousin five times over, and a 9th cousin ten times over and a 10th cousin twenty times over. It only cares the one relationship line that it came down, maybe via being 8th cousins, maybe via 10th. This has nothing to do with genealogy being used to guess at who the MRCA is, Debbie Cruwys Kennett, it has to do with the reality of what's happening to that IBD segment, which of course may not be able to ultimately determined, but we can simulate and statistically estimate. I could argue it from the top down as well. Take an IBD segment very small say 1 cM, and assume it doesn't get subdivided over 20 generations. Say that 1 cM segment belongs to a pioneer born in the 1600's. Say that segment is passed down 20 generations to two different people living today. Well, that segment has a 50% chance of being passed down to the pioneer's child. And on average, the pioneer's grandchild will only have a 25% chance of getting it. The great-grandchild is 12.5%. By the time we get to 20 generations, there is a 1 in a million chance that a person living today get that segment. Our pioneer will need 2 million descendants to average 2 people with this 1 cM segment so that there will be 2 who will match. Try that at 30 generations and it becomes unlikely you will find two people in the world with a 1 cM segment match that goes back 30 generations. Try it at 50 generations, and it is simply impossible. If those two people living today share that 1 cM segment, they must have got it from a descendant of that pioneer who is fewer generations back. Speed and Balding did a simulation of 50 generations with only 10,000 people keeping the population approximately constant at each generation. This is way less than the 8 billion people in the world today. I find it impossible to believe that over 20% of their 30 Mb to 40 Mb came from G > 20 from their simulation if the closest common ancestor who passed on a common segment was determined.
Louis Kessler replied to Andrew Millard's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Andrew Millard No. We are tracking a segment up through the two people's ancestors to find the common ancestor it came from. Once we get to that ancestor, we don't care how many other ways those two people are related. We are only interested in the one way they are related, and that is the one way through the one ancestor that passed the segment to both of them. The level of that ancestor defines the G in my analysis. My theory is that Speed and Baldwin did not do this but used the same thinking that you are using.

Andrew Millard -Yes, usually one. And from Speed and Balding Equation 5, the expected length of an IBD region for G=5 is 7.84 Mb, for G=10 is 4.05 Mb and for G=20 is 2.06 Mb. So again I ask: How is it that Speed and Balding Figure 2B shows that over 20% of matching segments between 30 Mb and 40 Mb are from G > 20 when the expected length of G > 20 segments is 2 or less? There's just something that doesn't make sense here.

Louis Kessler replied to Andrew Millard's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Andrew Millard - And I have what I think is sufficient reason to believe their numbers don't take this into account. If a person doesn't have at least a 7 cM match, then they don't show up in the match results. The problem I have is that people interpret Figure 2B as what they'll see in their own match results. Match results are filtered by the DNA company to be only people likely to be within 6th cousins or so. I doubt very much that Speed and Balding made that adjustment before presenting Figure 2B, so I believe the adjustment is appropriate. I really would love it if the authors could give us more insight into how they summarized their results, and whether they feel they are applicable to match results.
Louis Kessler replied to Andrew Millard's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Andrew Millard - There is approximately a one in 7 billion chance that two people with a common ancestor 20 generations back will share a detectable amount of DNA. Thus my doubt that among someone's match data, over half of their small segments come from 20 generations or more back. I claim my results are "similar" because the same conclusions would be drawn from either diagram: that over half of small segments come from a common ancestor 20 generations or more back. I listed some of the reasons for the differences. I could easily have made adjustments to my results to make them look more similar, e.g. simply move each of my bars one to the right, but there was nothing there that gave me a reason to do so. And do you really believe that over 20% of matching segments between 30 Mb and 40 Mb are from a Most Recent Common Ancestor who is 20 generations or more back?

Group: International Society of Genetic Genealogy (ISOGG)
Debbie Cruwys Kennett - They are generating the data and thus are generating the genealogies in their model. They know the IBD segment that the two relatives at generation 50 share. They can (and should) backtrack up through who passed each IBD segment to each relative (they know that) and determine the first ancestor in common who passed both of them that IBD segment through different children and thus different lines. This common ancestor is the MRCA and his/her generation is the one we want. The fact that this common ancestor gets the segment from his 10g-grandfather is irrelevant to us. We are interested in finding that common MRCA ancestor who passed on the segment and his/her G is what we need to know.

Thanks Debbie Cruwys Kennett. Their simulation type B starts with 5,000 males and 5,000 females simulated over 50 generations. They average about 2 children a generation keeping the population relatively constant. The statistics of that sort of model make it unrealistic to believe that in the 50th generation, people can have MRCA's that are greater than 15 generations, since in the 15th generation you'll have 32,768 g13-grandparents, but the model population at every generation stays at about 10,000.

I'll rephrase that in my article. I would love to hear what the authors would say about how they summarize their 2nd simulation. Maybe they do in fact do it correctly, and my analysis is wrong, but their paper itself does not give enough information to determine such. Blaine, I do suspect that very few Common Ancestors at 10 generations are correctly found. Ignoring pedigree collapse, that's 1,024 g8-grandparents on both sides and over 1 million possible combinations. How many of those are thoroughly researched on both sides, and how certain can one be that they've got the right line that the segment was passed down and that it wasn't another. Add to that a 2% chance of an NPE and we could find that 20% of those 1,024 g8-grandparents aren't genetically the correct ones.

I guess the other assumption most people would make here is that matches with the phased kit are valid. Unfortunately we can't say that for sure, especially with small segments. Even though you have phased your kit, the other person has not and the zigzagging can still occur over their paternal and maternal side. I definitely agree that phasing does eliminate many false segments as does triangulation as does parental filtering. But I also believe that small segments can be valid and should not necessarily be thrown out just because they are small. As long as the user is cognizant of the fact that small segments should be considered false until proven true.
Louis Kessler commented on Blaine T. Bettinger's post.
Group: Genetic Genealogy Tips & Techniques
Those two numbers are not a truly fair comparison. You are comparing a half match that either matches your paternal side or matches your maternal side or matches neither. But you are comparing it to a full match to just your maternal side. To be fair, if you also phased your paternal side, then you would then see what % did not share a segment with that kit. Then you could properly determine what is left over as guaranteed false matches. Let's say for example, that if you had your paternal kit and it came up with the same 67.4% as your maternal kit did. (It of course could be a bit more or less). Then assuming independence, which is a good assumption in this case because these are all supposedly unrelated people to you, 67.4% x 67.4% = 45.4% would match both phased kits. That would leave over 67.4% - 45.4% = 22.0% that only match the maternal kit and another 22.0% that only match the paternal kit. Finally that means that 45.4% +22.0% + 22.0% = 89.4% will match either both or one of your phased kits. So 10.6% won't share a phased match with you. You've stated that 5.87% don't share at least a half match with you. That indicates only 10.6% - 5.87% or just 4.73% of the people only share what would be a false half match with you.

David Boyles - Feel free to replace the name field in the CBR files you create from the GEDmatch data. But, you must make sure the names you use are consistent across all files you use in one run. No extra spaces, one person has exactly the same "name" in one file as in the other. Also, if the files produced don't have the name field enclosed in double quotes, then make sure you don't have any commas in the name, because they'll start a new field. If you still can't get it working, send me an email with them and I'll take a look.

Joe Bissett - Don't run them both ways. You always want a single person as Person A run against everyone else. DMT can already do this for you. Put the files of the people you want to compare with in a directory. Select the file of your Person A. Select the directory as Folder B, and check the Analysis by Chromosome box. This will run Person A one by one against each of the people in the directory, and combines the results, leaving each triangulation group from each run intact.. It produces one file per chromosome since putting them all together could make a file too big for Excel to handle. Running a person against a parent, or even a sibling is fine. But I don't see any reason for you to run yourself against one of your children. You get absolutely no information from that.

Now you know why I had to develop DMT. If the "b" is longer than the "a" for a match, it usually means Person B is related more closely to Person C than Person A is. Nothing wrong with that.
Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: Genetic Genealogy Tips & Techniques
Debbie Cruwys Kennett - Yes, exactly. And it is the probabilistic assessment, I.e. imputation, whose accuracy I question. We rely on their own assessment of the accuracy in their white papers, and I'd like to see a third party adjudicate that and show that phasing with imputation is better than triangulation without imputation, because I don't believe it is. Still, AncestryDNA isn't that bad. I just don't think it's that much better than FamilyTreeDNA, if it is in fact better at all. And imputation itself can be horrible as MyHeritage matches are proving. Roberta Estes is also critical of another case of imputation on her blog post today.

Louis Kessler replied to Debbie Cruwys Kennett's comment.
Group: Genetic Genealogy Tips & Techniques
Debbie Cruwys Kennett If phasing was perfect, then I'd agree. But when I've manually phased using the raw data of two parents and a child, I find more than 5% of the SNPs cannot be determined, either because all three had the same heterozygous alleles (e.g. all three were AG, or all three were TG, etc.) or because a no-call prevents the determination. That means more than 5% of the SNPs are imputed in some way by AncestryDNA (and everyone knows how I feel about imputation). So by imputing (filling in what may be unique with what is more common) and eliminating exceptions via Timber, they are doing more to average out the raw data. And that will cause more false matches. Yes by phasing you will very much improve matching, but that's if the phasing can be done accurately. Imputing by definition reduces accuracy. Imputing over 5% of the SNPs means that in comparing 2 people, about 10% of the comparisons will involve at least one imputation. The question is whether imputations on 10% of the SNPs compared will undo all the improvements that the phasing has done. Maybe the phasing with the imputation is better, but it is also possible that phasing with imputation is worse.

If that's your question, then there's no easy way. The names people use are different on the two systems, and only a percentage of people who tested at FamilyTreeDNA have uploaded to GEDmatch.

Debbie: I responded on my blog. Below is a copy of my response. I agree with everything you say (except maybe one thing, which I’ll likely write about in a future blog post). I was specifically talking about triangulation. Yes of course, a match between two people can be IBD. But the point of the article was to dispense with the notion that triangulation means IBD, as you taught me a year ago. Yes, inference can also result in false positives. My mathematical and statistical background makes me a big hater of inference. And the DNA industry seems to be getting deeper into that all the time. Soon a segment match won’t mean anything at all. My reads of AncestryDNA’s white papers leave me with little confidence in what they are doing. I’ve done the same parent-and-child comparison with FamilyTreeDNA as you did with AncestryDNA data, and my results show that FamilyTreeDNA gives significantly fewer false positives above 6 cM: http://www.beholdgenealogy.com/blog/?p=2003 I deal with endogamy. It seems like I have different observations than you do with your data. I match with 11,400 people and I have lots of triangulations. For example, I use my Double Match Triangulator program to compare my segment matches (my Chromosome Browser Results file) one by one with each of the 32 Chromosome Browser Results files that I obtained from people that I match with, none of whom are closer than a 3rd cousin. Comparing my file with one of those 32 files gives on average 3625 triangulations with 2344 people. Put together, that gives me over 100,000 triangulations to play with. But yes as you say, very few of these triangulations are within a genealogical timeframe which for me is only 5 generations. My thousands of triangulations are not just within certain pileup regions, but are everywhere. They encompass almost every cM of every chromosome. I am going to see if I can use all this mass of triangulations to put together my chromosome map that extends back at least a few generations and possibly even back to my 5 generation horizon. But it will take some ingenuity and programming as well as a bit of trial and error to do so.

Group: Genetic Genealogy Tips & Techniques
Leah: Absolutely. The incorrect assumption that the common ancestor is the 3GGF is the one that most people will make. I'm not saying that you always can determine the common ancestor. But you might be able to if you have other evidence. I'll try to explain what I said before, but more clearly: That extra evidence could be built up by triangulations over larger segments that contain the segment in question. There will be a subset of the people in the larger triangulation and the common ancestor of the larger triangulation will be a descendant of the common ancestor of the original segment. This can continue with larger and larger segments, ultimately to the persons paternal or maternal chromosome. Following it back through the parent, grandparent, great-grandparent etc., will lead as far back as your genealogical records can take you, into the direction of the ancestor who passed you that segment. Yes it is true that some other people in the triangulation group were passed down that segment through a different set of ancestors. But you're interested in figuring out who you got it from, not them. You're effectively trying to map your segments to the furthest back ancestors that you can genealogically (a la Kitty Munson Cooper). If your "furthest back" ancestor can go far back enough to get to the original common ancestor, then you'll have got the right one. But in almost all the cases, especially like your example, you'll only have got back to one of the many descendants of that original common ancestor. I don't like taking a triangulating segment and trying to find a common ancestor. Usually they are too far back, or have exactly the problem you point out. But I do like the idea of using triangulations to help build up a chromosome map of your ancestors from the bottom up.

Leah: This was my response to the comment you left me on my article: Re your 3rd possibility: Whether a segment is from a recent common ancestor or a distant common ancestor, it’s still the same segment from the same ancestor that all the people in the triangulation group have in common. Mathematically everything is correct and the triangulation is doing its job as stated. So then, as you state, the problem is in using this information to help you when the ancestor is too far back. I think we can come up with techniques to help figure that out, based on the idea that triangulation groups with a distant common ancestor often will be contained in a larger segment having a triangulation group with fewer people from a closer common ancestor. One of the techniques I’m looking at is to start big (as far as segments go) with the largest triangulations and work your way back in time by finding smaller segments with triangulations of additional people.

Group: International Society of Genetic Genealogy (ISOGG)
Thank you, Ann. I've not tested with 23andMe so I didn't know about their ability to show someone else as their primary person. That's a great feature. I'm updating my article and giving you credit for this new infomation. From a mathematical analysis, I am pretty sure you would only need 3 people's matches, A, B & C to triangulate an unlimited number of people: D, E, F, G, .... into the same triangulation group (which is what I horribly named: Triple Match Quadrangulation). Using only two people, A & B, will determine all the triangulations, but those might include some triangulations with matching segments on different paternal chromosomes. So no, you wouldn't need to compare D & E. If you add F, you wouldn't need to compare D & E, D & F or E & F. Etc. What you will find, however, is that some people may not have enough total cM to make a match criteria. They may match just on a few small segments including the one of interest. But you can't tell because they are not an overall match for you. You will then need to match them on the segment with a third person from the triangulation group to prove that they belong.

That is a relationship though an ancestors' paternal side switching to the maternal. The segment actually crosses over there. The two matches are adjacent to each other on the same chromosome.

The chance of two 8th cousins sharing DNA is very small. Finding genealogically that you are 8th cousins with someone does not mean that the DNA shared is all from the common ancestor you discovered you have. Some may be from other common ancestors through other lines. In fact all may have been through other lines with none of that shared DNA through the genealogical line you've discovered. The way to try to determine this is through the triangulations with other matches. You can try to link up some of those triangulations to this side of your family. The 8 cM segment has potential. Who else in your family matches on that segment on the same side (paternal/maternal)? Are they on the correct line? Be wary of the < 5cM matches as many of them may be by chance.

What I'm interested most in is if there's a bias between companies, e.g. that for 3rd cousins, FamilyTreeDNA averages 30 cM higher than GEDmatch. If in additon to the overall median, you could give the median for each company for each relationship, that would indicate any differences.

Isn't it important to give separate ranges for the different testing companies? Don"t they each have different criteria for determining how small the segments are that are included in the totals and have different exclusion areas?
Louis Kessler commented on Sheryl Prenzlau's post.
Group: Jewish DNA for Genetic Genealogy and Family Research
Seems about right. Don't worry. Don't even bother looking at the total match. Matches with largest segments of 20 cM or more are worth a look. I have 11,422 matches, and only my Uncle (who I tested) and a 3rd cousin (who I had already been sharing research with before I tested) are known relatives. On FamilyTreeDNA, my third cousin and I share a largest matching segment of 21 cM out of 107 cM total match. He's in 59th place in my match list when sorted by largest segment, but well hidden in 750th place when sorted by total cM. Much of the problem in identifying common ancestors any farther is that Eastern Europe Jewry only adopted surnames about 5 generations ago, and I have cases of brothers and sisters back them with different surnames.
Louis Kessler replied to Sarah L M Christiansen's comment.
Group: Jewish DNA for Genetic Genealogy and Family Research
That is true, Jennifer. But DNA effectively has the same problem in that as you reach 5 and 6 generations back, you start losing some of your DNA ancestors, and thus lose some of your ethnicity in your DNA estimate. You can replace NPE's with the birth parents in your pedigree chart as you discover them, but you can't add the missing ancestors to your DNA. DNA gives a decent overall estimate of ethnicity that could help adoptees and others who know little about their parents origins. But don't expect precision in those estimates. Percentages less than 10 can be noise.
Louis Kessler replied to Sarah L M Christiansen's comment.
Group: Jewish DNA for Genetic Genealogy and Family Research
Our point is that exactly because of what you are saying, DNA is a poor way to estimate ethnicity. A much better method would be to simply calculate it from your genealogy pedigree chart using the ethnicities you know your various ancestors are. Doing so for myself, I would be 100% Ashkenazi, and I wouldn't have 2% Irish or 1% Eskimo in me like some of the DNA estimates give.

I agree. Alone, these extra random matches could show up. But for this type of random small segments, techniques such as phasing or parental filtering eliminates these false matches and likely triangulation will eliminate most of them as well. I would agree that small matches that have not gone through at least one scrubbing process should not be used.
Louis Kessler commented on his own post.
Thank you Debbie Cruwys Kennett. We do know that triangulation and other techniques like parental filtering can eliminate many segments that are not real. But yes, it looks like we need someone to do a scientific paper about the other techniques with respect to how good they are at identifying real segments.
Louis Kessler commented on his own post.
Debbie Cruwys Kennett - Absolutely! The real world will be different than a simulation. Phasing is one of the best techniques to help identify possible IBD segments, but it is not the only way.

I agree that noone should start off by looking at small segments. But through techniques such as phasing and triangulation, you increase the likelihood that small segments are real and they can be later used to support your conclusions. So I'm saying not to simply throw them away because they may prove useful.
Louis Kessler commented on his own post.
Thank you Angie Bush for you comment. I agree totally with you that small segments should not be used as proof of anything. But there's nothing wrong in using them to support work that includes larger segments, phasing, chromosome mapping and genealogical research that has proven relationships.

It is very important to study the "pseudo-segments" as they are called in CeCe's article that you link to. I don't think enough work has been done with regards to this and that is what my article was primarily about.
Louis Kessler commented on his own post.
Debbie Cruwys Kennett - Thank you for your comment. I was hoping I would get a review from an expert.

I agree with everything you say. I agree that you cannot conclude that small segments are IBD. And I agree that many of the small segments that are IBD may be beyond the genealogical timeframe.

And I believe I was very careful in my article to indicate only that small segments may be IBD.

The chart from the Speed and Balding article that you link to does indicate (if you interpolate the x-axis correctly in Chart B of FIgure 2) that a 2 to 5 Mb match (on average the same as a 2 to 5 cM match) will be IBD within 10 generations about 8% of the time. And a 1 to 2 Mb match will be IBD within 10 generations about 4% of the time. This actually agrees with the result of my study on Non-Matches by cM http://www.beholdgenealogy.com/blog/?p=2003 that found that 80% of matches from 1 to 2 cM are proved non-IBD because neither parent has the match. I did not mention in the article because it was work in progress, but I have indications that you also have to consider the matches' side and there's another 80% of the remaining 20% where neither of the match's parents match. Thus 20% x 20% = about 4% of 1 to 2 Mb matches will have a parent on each side matching. Again, I'm not saying that these are IBD segments, but they are now good candidates.

I don't know. I only mentioned that because of the article Jeff Wexler refers to above, where the author says Abraham must have belonged to three different haplogroups.
Louis Kessler commented on Calvin Lawrence's post.
Group: Jewish DNA for Genetic Genealogy and Family Research
This is an excellent question, but I think the reasoning that must be used is quite different than what anyone has posted so far. To be considered Jewish, either the mother must be Jewish, or the person converts to Judaism. Looking from a Jewish person up to Abraham through his Y-line, any paternal ancestor could have been non-Jewish but had a Jewish wife, and may or may not have converted to Judiasm. This explains why Jewish people could have different Y-DNA haplogroups. They all need-not have descended from Abraham. Looking down from Abraham, who indeed may have started several Y-DNA haplogroups but need not have, any male-line descendant may have had children with a non-Jewish woman and thus those descendants are no longer considered Jewish. Therefore, Abraham would have a lot of non-Jewish descendants on his Y-line down. So now let's ask about Abraham's wife Sarah. Most Jewish people should have a better chance of their mt-DNA being the same as Sarah's because of the mother-defining-Jewishness law. However, there are still going to be conversions or hidden adoptions or even mistakes (babies switched). So the mother's mt line should be better that the father's line for Jewishness, but both will vary on their way up or down to and from Abraham and Sarah. The Muslim religion is passed down from the father. So if Ishmael was indeed the patriarch of the Arab nation, then the Y-DNA connection of an Arab person to Ishmael and thus to Abraham should therefore be better than a Jewish person. That would probabilistically make it more likely that Abraham had Arab Y-DNA than Jewish Y-DNA.

Louis Kessler commented on Family History Information Standards Organisation's post.
I'll have to think more about this. It's different and may be tough for developers to implement. Here's some of my initial thoughts.

Your example to me seems equivalent to the following in GEDCOMish:

1 CREA
2 TYPE Author
2 NAME Christian /Settipani/
1 TITL Les ancêtres de Charlemagne
1 PUBL Prospographia et Genealogica
2 PLAC Oxford
2 DATE 2015
1 PAGE Edition: 2nd ed, pp: 129-31

I'm not a fan of having span tags and using the "name" attribute to represent what the item is. The second attribute "role" should be a subattribute of the main attribute and I would prefer to use "type" to role.

I don't like formatting such as <i> within citations. Developers should be allowed to format citations as they like. Only text from the source should be allowed formatting and only if the formatting is an important part of the data.

Most developers now are going away from XML and are moving to JSON.
Louis Kessler replied to Reif Hammond's comment.

Joe Bissett - Reif is correct. In a triangulation group, for all people in the group, taking any 3 of them would give triangulation A=B, B=C, C=A on that segment. And there are two possible triangulation groups on any segment, maternal and paternal. With a match of at least 5 cM (better is 7 cM), the triangulation group likely indicates a common ancestor and that the segment was passed IBD to all the people in the TG.

Jim: Yes, false negatives are IBD. So if they are included, they should count as a match. Most studies incorrectly count them as a non-match. The trouble is that you can't tell if they are a false negative or if they are just false, so it's better to eliminate them from the counts.

I agree with you Blaine, that for the purposes of finding ancestral segments, parent/child pairs should just be used as one side of triangulation. But I also agree with Tim Janzen that parent/child pairs is great for maternal/paternal filtering. In addition, using parent/child pairs immediately eliminates false child segments that do not go through the parent and thus makes using a parent/child pair more reliable than using just the parent or just the child.

I've found that a good measure is the percentage of your matches that match to both your father's and mother's side. In some father/mother/child tests I've done, I've found non-endogamy sits at about 0.3% and endogamy sits at about 3.0% See my table below that is from my blog post: http://www.beholdgenealogy.com/blog/?p=2003 Of course, that information is not supplied by the companies, so the next best way might be to ask each person how many total matches they have. In my table, the endogamous group averages over 6 times as many matches as the non-endogamous does. So then divide your analysis for each company into the 50% with the most matches and the 50% with the least matches and call the first group "more-endogamous" and the 2nd group "less endogamous".
Louis Kessler replied to Blaine T. Bettinger's comment.
Group: Genetic Genealogy Tips & Techniques
That's a great idea to do the analysis by company. Unless there are very clear instructions as to how to remove small segments from totals, I wouldn't expect that each submitter would do it in a consistent manner. So I think it is best to just ask for the raw numbers from each person along with the company, and analyze each company separately. Doing so would have the added advantage of allowing people to use your "by company" table directly against their raw totals. This would then show how the companies numbers compare with each other, which would be very useful. What would also be very useful is if you could figure out a way to ask how much endogamy their ancestry has and then you might be able to estimate how much the ranges enflate with endogamy. Some companies say they adjust for endogamy in some cases, but do they? An example of the inflation is on Lara Diamond's recent blog post. https://larasgenealogy.blogspot.ca/2017/03/endogamy-in-practice-updated.html

That's highly improbable. Matching segments longer than 15 cM are almost always IBD and come from a common ancestor. One large segment can be passed down many generations. And we have so many thousands of cousins, that it's quite likely that two cousins could have got the same large segment, even though they might be 4th or farther cousins.

The study I did a few weeks ago: Non-Matches by cM http://www.beholdgenealogy.com/blog/?p=2003 seemed to have quite a few of these cases. I didn't quantify them then, but maybe when my wife and I get back from our current vacation, I will, and I'll give my results in a new blog post. I think the "more" on a single segment can be quite significant since random single matches can be 10 cM.
Louis Kessler replied to Wayne Kurtz's comment.
Group: International Society of Genetic Genealogy (ISOGG)
The total cM for the child averages to being half of the parent's, but due to by chance matching, the child can match where neither parent does. Or where the child and parent both match, the child's match can be longer with a bit of random match on either end of the match.

Group: International Society of Genetic Genealogy (ISOGG)
Sharon. This is great that you're using DMT to help with your GEDMATCH results. I'd be very interested in anything else you learn from it. With regards to TG's, remember that each one is built up of smaller TG's that belong to the ancestors of the ancestor from the fist TG. Selection of the bigger TGs or the smaller TGs is arbitrary. DMTselects based on an overlapping segment algorithm that Jim Bartlett suggests. It usually comes out with intermediate level TGs.
Louis Kessler replied to Sharon Bunter's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Of course reading errors and algorithmic problems and mutations and other odd genetics irregularities are always the exception. But ignoring those, all our DNA comes from either our mother or father and so on up the line, so every non-mutant segment ultimately is IBD coming from someone. It is the attempt to figure out who these ancestors are that pileups cause combinatorial problems with because it goes so many generations back and there's too many possible people who can be the ancestors. That's complicated even more by endogamy and two people being related in multiple ways, resulting in many possible lines through which the segment could be passed down from the ancestor.
Louis Kessler replied to his own comment.

Debbie Cruwys Kennett - The FTNDA Family Matching Tool could very well be doing something similar to Double Matching. They give what seems like a decent explanation of what they are doing, but they don't tell you precisely how they're doing it and they don't give you access to the raw data results of what they've done which they are keeping as proprietary. They're only giving you the marking on your matches of "maternal", "paternal" or "both".
Louis Kessler replied to Sharon Bunter's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Pile-ups are still made up of IBD segments. So they still have to occur within Triangulated segments. It's just that the most recent common ancestors (MRCA) whose provided the DNA in those pileups may be so many generations back that they may be unidentifiable through genealogical records.
Louis Kessler replied to Sharon Bunter's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Sharon Bunter - I was thinking all night about your paternal Triangulation that shows up on GEDmatch among your maternal Triangulations. You said that it doesn't show up in your Triangulations produced by Double Match Triangulator. GEDmatch is indeed showing you all your Triangulations. But they are ALL the Triangulations you have with any two people and they are all shown together. So GEDmatch is giving you paternal and maternal Triangulations together. It is not differentiating. DMT is differentiating. The person you selected as Person b is basically a filter. DMT is showing you only people who are related to both yourself (or your Person a) and the Person b you are using. If Person b is a 2nd cousin on your mother's side, then DMT will filter to only include people on your great-grandparent's side that are in common with your second cousin. And DMT does it much stronger than Don Worth's Autosomal DNA Segment Analyzer does, because it is not just checking that the people are "In Common With" each other, as ADSA does, but it is actually checking that the segments align, i.e. true Triangulation. The proof would be for you to look at the People page in your DMT results. I'm sure you'll find that the person on your paternal side who GEDmatch has you Triangulating with, will be on DMT's People page listed as a "Missing b-c Match". So DMT is not including that paternal Triangulation person because that person does not match the Person b you used for the run on any of the same segments and in particular, not on the segment that is part of the Triangulation Group you are interested in. I hadn't thought about this situation because I never compared to DMT to GEDmatch in this way before, so thank you very much for making me aware of it. The bottom line is: GEDmatch uses single matching and produces all true Triangulations for Person a and any two other people. By comparison, Double Match Triangulator uses double matching and produces all true Triangulations that involve both Person a and Person b and any other person. So DMT filters the Triangulations to only segments where Person a and Person b match. If the Triangulation is IBD (it might not be due to a chance match or the endogamy situation), then the IBD people in DMT's Triangulation Group will be effectively "filtered" to the Person b side of the family. And because you can choose whoever you want as Person b with DMT, if you have a few Chromosome Browser Results files from different relatives on different sides of your family, you can effectively filter your Triangulation groups to the various sides. And then, by using DMT's "Analyze by Chromosome" selection, you can put all the different filtered Triangulations together so you can compare them. Thanks, again, Sharon, for being persistent and asking about the Triangulation Groups and why GEDmatch is mixing the paternal and maternal Triangulations and DMT isn't. I'm still learning myself what Double Matching is capable of. This filtering aspect seems to be a very important ability that it has. I'll have to explore this further.
Louis Kessler replied to Sharon Bunter's comment.
Group: International Society of Genetic Genealogy (ISOGG)
If the person you use as Person b is on your mothers side, then most of the people in the Triangulation Group should be on your mother's side. Endogamy or your mother and father being related are examples of what can wreck that up. One clue might be the base addresses of the ends of the double match area (green X's). If a bunch of them are the same address, I suspect they are likely to be in the same Triangulation Group.
Louis Kessler replied to Sharon Bunter's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Sharon, I have good news and bad news for you. The bad news is that they don't necessarily fall into the same Triangulation group. The good news is that each person has to belong to just one of two Triangulation Groups: either the paternal side or the maternal side. I'm still working on methods to split them apart and hopefully a future version of DMT will do this for you. Remember as well that some of the smaller segment matches can be matches by chance. I'm currently researching how small this "small" is. Interpretation of the output of DMT is still a work in progress.

Louis Kessler replied to his own comment.
Group: International Society of Genetic Genealogy (ISOGG)
Debbie: What I believe Blaine T. Bettinger has demonstrated in his simple counterexample, is that if you don't have the 3 matches of Triangulation phased, then they won't necessarily be coming from the same chromosome. In a Triangulation, If the a-b match is from the paternal side and the a-c match is from the maternal, then it will not be IBD and because those are two different segments. So it seems he has extended what "true" triangulation means to also require the phasing. Blaine is still thinking this over. So what that likely indicates is that GEDMatch's tier 1 Triangulation is probably not doing this either. They do have the raw data, but neither Kitty Munson Cooper's article about it, nor the GEDmatch article indicate that they're phasing the segments prior to comparing them. The saving point is that Blaine pointed out that Jim Bartlett has said that his experience with Triangulated segments are that they are almost always valid (likely above his 5 cM threshold), and that likely was without the requirement of phasing.

Every segment comes from someone. Even if they pile up, I believe they can be subdivided and analyzed by crossover point and common descendants.

Actually David, this analysis by Roberta and then by me for endogamous people, is only showing what we already know: That there are a lot of false matches when you have short segments. Maybe the percentages are a bit different for parents who are related, but you still don't want to use small segment if you're Single Matching. This is actually just the first step of my analysis. I'll be working to follow this up with an analysis of percentage of false matches when you Double Match and/or Triangulate. Jim Bartlett believes triangulation is reliable down to 5 cM with very few false matches. No one has attempted to analytically determine this yet. I need to do this so that I can better direct users as to how to treat small segments in my Double Match Triangulator program.
Louis Kessler replied to Dave Bindon's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Dave Bindon - I've been trying to logic through this to figure out if it's a big problem. Does this make sense to you: If 2 out of 12 matches are false (as proven by the parents), then the child will have 2 false matches to Person c. Similarly, Person c will have 2 false matches to the child. However, Person c's false matches could be to the child's mother's side, or to the father's side, but more likely it is to a combination of the two, crisscrossing between them. So from Person c's side, of their 2 false matches with the child, only the ones that match enough with the father only or with the mother only will end up being the problem ones for your case. The ones that crisscross too much won't match the child through either parent and will already have been eliminated on the child's side. So what you'll be doing with your double cousins is finding out what percentage of their random matches with their cousin are only invalidated through one parent rather than both of them. Will that be 2% of the time, 10% of the time, 50% of the time? Hard to hazard a guess until you check.

... And we do see that issue from the parent/child side, where the child has, say 12 segments matching X but the parent only has 10 because 2 are false. Your situation is where the parent/child both have the match but it is false from the X's side. Because of the double match showing IBD on the parent/child side, I just think that situation is less probable.
Louis Kessler replied to Dave Bindon's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Yes, you could. But I don't think this is an important issue, because that person X has to have enough total cM matching and at least one segment of 7 cM minimum for person X to be considered a match. FamilyTreeDNA set the criteria so that most of the people called a match would be a match with few false positives. So most of those segments of person X should match the parent and child. You may have 1 or even 2 that match being a random match from X's side, but I would guess that is much less probable than the match being due to the segment being IBD.

Last night Roberta Estes sent me her files so that I could do the analysis with her data. So far, I've found that I can reasonably closely reproduce her results, so that means my spreadsheet is doing the same/correct analysis as Roberta did. I've also found that Roberta's cutoff at 3 cM adds non-matches at the 3-3.99 cM and some at the 4-4.99 cM as well because the parent's segment must have been just under the 3 cM cutoff. Should be able to figure out more later today. Also, Roberta's data has a 2nd child as well which she didn't analyze for her blog post, so I'll add that to the mix. Plus someone else emailed me another set of parents/child CBR files that I'll also take a look at.

Louis Kessler replied to Dave Bindon's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Yes. I noticed this as well and excluded these in my analysis. I gave the reason in my blog post as being date of download, but threshold limits would do the same thing. I described what I did in my blog post to get around this as as: "I found the best way was to see if the child had matches to a Person c that neither their mother or father had. For this Person c to show up in the child’s match list, they had to have at least a half dozen matches totalling at minimum around 20 cM. For that to happen and for none of those segments to match either parent is practically impossible meaning the matches for the parent is missing. So I deleted these from the analysis. They amounted to about 5% of the matches and did not really change the results other than reducing the number of large segments that did not match."
Louis Kessler replied to Dave Bindon's comment.

You are correct. But to test this, you'd need to have the matches of both parents of every single X. So it really can't be tested.

Okay. Compared two of Sandy's cousins in the two files. For Bruce, 6 of the 7 matches on 23andMe are about the same cM overlap on their base addresses on the same Chromosome/ There is one match on 23andMe of 5.79 cM that has an equivalent of one that is 6.14 cM on FamilyTreeDNA but the first is from 26 to 31 Mbp and the other is from 46 Mbp to 48 Mbp. For Sylvia, all 12 of the 23andMe matches have corresponding FamilyTreeDNA segment matches, although one of them is shown as two segments at FamilyTreeDNA. Also FamilyTreeDNA has a 7.63 cM match on the X Chromosome that 23andMe doesn't show. Thanks Sandy and Ann. This has told me what I needed to know. As you said Ann, they are different builds so they can't be compared exactly against each other, but 23andMe does have useful segment matching data that can be analyzed.

FamilyTreeDNA gives the person's email address, which is really important and Match Date.

From the FamilyTreeDNA file Sandy gave me before, it shows 144,956 segments for 7,016 people. When I count only 5 cM or greater, then it gives 28,787 segments for the same 7,016 people., which is 4.1 segment matches per person. By comparison, her 23andMe file has matches with 921 people, of whom 457 are private and hide the segment match information. For the other 463 people, there are 3117 segment matches which is 6.7 matches per person. Now I'm going to look to see if there are matches in both files so I can compare the actual base addresses of the matches. Of course, names won't be the same in the two files, but we'll see.

There is no guarantee that the 20 cM segment is from the same ancestor of the paper trail. Common cousins who have been DNA tested will be need to be included in the study before there would be any level of confidence that the two are the same line.

Caz Brymora Unfortunately, no. I'd would want to use FamilyTreeDNA only because I am very aware of all the details and nuances of their data. GEDmatch severely limits the matches it will provide and does not have as low a cM threshold as FamilyTreeDNA. And I don't know if transferred data from AncestryDNA will align well with tested data at FamilyTreeDNA. IMO, FamilyTreeDNA is the most open in that they allow you to download your own data and is the best to use if you are going to do a detailed study.

Caz Brymora - That would be a fantastic test case. I'd be happy to add yours to my set and maybe even then show the effect of Endogamy vs non on IBS matches. I'd keep your data private and not give it to anyone and the results I produce will be anonymous (just talking relationships). And I will definitely credit you for providing the data for the study. It must be from FamilyTreeDNA though. And I would need two files for each person: (1) from the Family Finder - Chromosome Browser page, I'd need the "Download All Matches to Excel (CSV Format)" file, and (2) from the Dashboard page, I'd need the "Download Raw Data" Build 37 Raw Data Concatenated file. I'm intending primarily to use the 1st file, but I'll also like the 2nd to be able to determine what's going on in case of ambiguity. Some of the files might be large and take a up to 30 seconds for FamilyTreeDNA to respond and generate it after you click on the link. So for that many people, it may take as much as an hour or two for you to obtain all the data.
Louis Kessler replied to Sandy Aaronson's comment.
FamilyTreeDNA saves matches by the match's name. If two different people have the same name or someone tests twice, they will be incorrectly merged in the CBR file, something FamilyTreeDNA does wrong. Duplicate or overlapping segments indicate this has happened. Version 1.2 detects these, deletes the dups, and indicates this happened with the ##. I explain this in the Help file.

A study like this is analyzing what I call single matching. Double matching, where Person a matches Person c and Person b matches Person c likely reduces the IBS threshold down to 5 cM as Jim Bartlett has concluded for Triangulation. In fact, double matching a person with their parent eliminates all matches that they both don't have. There will just be a few segments where the child will have a bit of excess due to chance matches. I plan to do a study of this in the next couple of months using a father, mother, son, daughter, uncle and cousin from an endogamous population. I'll post the results when I'm done.

That overlaps with a different person c who is 7 lines down that has an a-c match of 9.31 cM and a b-c match of 15.31 cM that double matches for 9.31 cM. These are significant numbers! And in addition, there's 11 other people who interact over that region, some with identical crossover points. I just feel there has to be something meaningful to pull out of this.
Louis Kessler replied to Sandy Aaronson's comment.
Group: International Society of Genetic Genealogy (ISOGG)
I don't really know yet. But when I compare crossovers from different people to the same Person c, they seem to match exactly. I am guessing that FamilyTreeDNA's algorithm does do a good job of determining crossovers that will be consistent for a particular segment ... but again, this will have to be researched and verified. I wish I had 10,000 hours where the world stopped.
Louis Kessler replied to Sandy Aaronson's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Also, I wouldn't just throw the missing a-b double matches away. I think they can be very valuable, especially if there are large matches > 10 cM. It may indicate a common ancestor IBD who passed the segment to Person a and Person c through one descendancy path, and to Person b and Person c through another descendancy path which is why Person a and Person b don't match. With pedigree collapse and endogamy, we should all have many of these. But until my DMT program, there hasn't been an easy way to identify them, so no one so far has studied this.
Louis Kessler replied to Sandy Aaronson's comment.
Group: International Society of Genetic Genealogy (ISOGG)
I think the key to analysis is to look at the crossover points. This is what I want to study. If multiple people have identical crossover points, it reduces the likelihood of it being a by chance segment. Those crossover addresses are very accurate and seem to match up. More research again is needed.
Louis Kessler replied to Sandy Aaronson's comment.
Group: International Society of Genetic Genealogy (ISOGG)
That isn't necessarily the case. Person a may match Person c over 10 cM, and Person b may match Person c over 12 cM, but their overlap may only be 1 cM just because of the way their segment got passed down.
Louis Kessler replied to Sandy Aaronson's comment.
Group: International Society of Genetic Genealogy (ISOGG)
Sorry but that is correct. Fully triangulated segments can still be by chance as I just described. I discussed this with Debbie Kennett and realized she is quite correct on this point. It does make it less likely and anything over 5 cM that is Fully Triangulated is likely IBD (according to Jim Bartlett), but studies will have to be done to see how small is small for triangulation.
Louis Kessler replied to Sandy Aaronson's comment.
Group: International Society of Genetic Genealogy (ISOGG)
A small triangulated segment still has a high probability of being by chance. If person a and b are IBD, then if person c matches a by chance, then person c will also match perbson b by chance.

With all due respect to David Pike who's a fine fellow that I met a couple of months ago at the Ontario Genealogical Society Conference, if he is using the term "double segment match", then he may be the one using the incorrect terminology. According to the Glossary in the ISOGG wiki, as well as many other reputable sources, the terms for segments matching on one chromosome and on both chromosomes are "half-identical region" (HIR) and "fully identical region" (FIR). With regards to the term "double match", I am referring to "a matches c" and "b matches c" on a segment. Only if "a also matches b" on the segment is it a "full triangulation", otherwise it is a "missing a-b". I use "full" with the term triangulation to distinguish it from the "triangulation" that many other incorrectly use to mean "a matches b" and "a matches c" on a segment and "c is in the in-common-with (ICW) list of a and b".

Thanks for the screen shot Kathy. It tells me what's going on. DMT creates a csv file first. If it detects that your computer has Excel, it then tries to use the Excel libraries on your computer to load the csv file into Excel, and then it formats it. Something on your computer (I don't know what) and on 5% of people like you is preventing the Excel from working. You said you have Office 2007, so that's okay. I've only tested that back to Windows 7. Do you have Vista or Windows XP? You can still start from the csv file. Newer versions of Excel load it automatically. In your case, you have to open it as a text file. A text import wizard should start. Tell it that your file is delimited, with headers, and the delimiter is a comma. That should load the file into columns. To color the boxes in the map file, I use conditional formatting. I set up cells that contain "X" or "Full triangulation" to be green, cells with "a" to be pink, cells with "b" to be blue, cells with "." to be yellow. I freeze panes at cell O2. I set the view down to 70%. Then I select all the columns and double click between one of them with sets them all to the proper width. That is basically all that the loading into Excel does, so it really only takes a few minutes to set that up once if you know Excel. Then you can copy that formatting to other files.

The Jewish people in Romania and Ukraine only adopted surnames in the 1800's

Even a paper 4th cousin would be wonderful.
Louis Kessler commented on Randy Seaver Geneaholic's post.
An 8th cousin! I'd be happy if I could validate my first 4th cousin.

On FamilyTreeDNA, my uncle Harry Braunstein matches to Henry S Greenberg, Robert Greenberg as 3rd-5th cousins, Alan B. Greenberg and Maxine Greenberg as 4th-remote cousins, and Arthur Greenberg, Jason Greenberg, Stanton Greenberg, Daniel Benjamin Greenberg, Harlan Greenberg, Jeri Greenberg, Jon Michael Greenberg, Leonard Greenberg, Matti Greenberg, Rosalie Greenberg, Susan Ericka Greenberg, Susan Nancy Greenberg and Roberta Greenberg Brezinski at 5th-remote cousins. But of course Greenberg is a very common name, and all Ashkenazis are related.

Maia: As Jeff says, we're likely clutching at straws trying to get a Y-DNA connection. But your best bet is still to pursue autosomal connections with others in the Botosani group. You might also want to try transferring your DNA to FamilyTreeDNA (I believe it is only $45) because I believe they have the largest Jewish database. My uncle has over 7,700 matches, of which I only know 1 connection for sure so far.

Luc: Maybe, but likely closer. According to FamilyTreeDNA, a GD of 5 at 25 years per generation gives a 2 out 3 chance of being within 300 years, and a GD of 3 gives a 2 out of 3 chance of being within 200 years.

He lives in Israel. He's involved in the Levite Y-DNA study: https://sites.google.com/site/levitedna/home https://www.facebook.com/LeviteDNA

With all the endogamy in the Ashkenazi, I wouldn't be surprised if they show up as a match at 4th cousins. But the line could be traceable on the Y-DNA side if they match. My uncle's line is Levite, and is in Meir Gover's study. If Maia knows that his paternal side is Levite, then he should do a Y-DNA test at FamilyTreeDNA and he will find out a lot more about that line. A possible Y-DNA connection from Botosani interests me.

There are two Greenbergs: Michael Harvey Greenberg and Phillip David Greenberg who at FamilyTreeDNA match on their Y-DNA67 at genetic distance of 3 and 5 (i.e. 6 to 10 generations back) to my uncle Harry Braunstein. My line is from Tecuci, not too far from Vaslui or Iasi. My uncle is on GedMatch. See if he shows up in your matches there.

I have Focsaner, Segal and Hertzan family from Ungureni and Dorohoi. I believe but have not yet confirmed that the Hers Focsaner, buried 01 Jun 1913, Block F Row 4 Number 7 in the Botosani Romania cemetery (13,198 burials) from the JewishGen Online Burial Registry may be my great-great-grandfather. I have more information about those families at: http://www.lkessler.com/myfamily.shtml#foc My 93 year old uncle who is connected to them has been DNA tested at FamilyTreeDNA and will appear as Harry Braunstein. If you think you might connect with the above information, or if your DNA matches to my uncle on FamilyTreeDNA, please let me know.

Hi Shelley, I've traced back our Herman side to the town of Mezhirichi in the province of Volhynia in what is now the Ukraine. I haven't DNA tested on my Mom's side yet. The Kushner side is my wife's side (not DNA tested) and was from Lukashevka in the Ukraine. Where were your Hermans and Kushners from?

Linda: The Zaslavsky family is on my wife's side. As it turns out, she has a cousin who is a serious genealogist who does all the Zaslavsky family research and I refer most people to him. His name is Terry Lasky and in 2013, he wrote a 246 page book on the Zaslawsky Family History. Looking through his book, which lists several different families that he's still working to connect, I searched for many of the names and places that you list above and it does not appear to me that your Zaslavsky's are in there. But don't give up hope. Terry is currently a committee member of the Colorado Jewish Genealogical Society. They give his email address at the bottom of the page http://jgsco.org/about.php when you click on his name. I know Terry will be interested in hearing from you. He has more material in his research than just what's in his book, so he may know of your family. Terry has tested on FamilyTreeDNA. If you have, see if he is a match to you and contact him directly through there.

The main family names I'm researching are: Braunstein, Meraru, Focsaner, Segal, Hertzan (Romania) Kesler, Katkow (Russia), Herman, Lapides (Mezhirichi, Ukraine) Goretski, Silverberg (Odessa, Ukraine) Kushneer, Lerman (Lukashevka, Ukraine) Zaslovsky (Tetiyev, Ukraine) Furman (Zhitomir, Ukraine) Muchnik, Dubowa (Kondia, Berdichev, Zhitomir, Ukraine) I've got more info up at: www.lkessler.com/myfamily.shtml And I recently got my uncle's DNA results up at FamilyTreeDNA. If you match to Harry Braunstein and have some family names or places in common, please contact me.
