View Full Version : Anthrogenica Users Segment Sharing

Have you ever thought that your kit could generate a match to another Anthrogenica user? Due to the anonymity of the site we don't openly share personal emails (or names) with other users. Such does allow for more freer communication of ideas, but it may keep you from finding out that the people you talk to are actually very distant relatives.

To quote ISOGG: "A long consecutive string of half-identical SNP results (typically about 5 cM / 700 SNPs, depending on the test's error rate and other factors) is required before one can say that two matching DNA segments are probably identical by descent." It also indicates that Ancestry.com changed to this standard earlier this year.

I have recently run my kits on GEDmatch verses that of two Anthrogenica users. I maintained the default "minimum threshold to be included in total = 700 SNPs" --which maintains the "mismatch-bunching limit =350 SNPs" but I lowered the "Minimum segment cM to be included in total" to 3 cMs. For comparison to one user, two of my kits generated multiple segments > 700 SNPs. The comparison of another user's kit found one segment over 6 cM in length when compared to two of my kits, and other segments that also met the >700 SNP criteria.

According to ISOGG, if our mutual kits were tested at Ancestry.com, that of mine and the latter user, would have been in each other's match list because they changed to these minimums earlier this year.

It's blurring the line between genetics for genealogy and genetics for admixture but it's nice to find out that users could share minimum IBD segments. No wonder we have similar admixture percentages :)

I started this thread in case users who had run such comparisons on each other's kits wanted to share their results with the general community.

Well, I did eventually find out that I'm related to two Jews, an ethnic Turk and an ethnic Pole on other forums so I get the gist, in a sense.

Yep, ethnicity is a man made construct. I mean there are geology that can isolate groups, but what we consider ourselves is often taught. I mean we are very homogenous - I think 99.9%. It's a pity more Denisovans/Neanderthals didn't survive to mix up the gene pool more :biggrin1:

Threshold: Minimum segment length set to 3 cMs. Minimum size set at 700 SNPs.

Erik matches David Powell:
for 3 segments that have over 700 SNPs.
Erik matches David Powell's mother:
for 4 segments that have over 700 SNPs.

Comment: The segment lengths reported above vary from 3.0 cM to 3.9 cM. Two of the segments of match between my mother and Erik I don't have. I have one segment that they don't share, I suppose inherited from my father.

Threshold: Minimum segment length set to 3 cMs. Minimum size set at 700 SNPs.

Erik matches David Powell:
for 3 segments that have over 700 SNPs.
Erik matches David Powell's mother:
for 4 segments that have over 700 SNPs.

Comment: The segment lengths reported above vary from 3.0 cM to 3.9 cM. Two of the segments of match between my mother and Erik I don't have. I have one segment that they don't share, I suppose inherited from my father.

Salkin has agreed to that I can share information on our segment matching.
I found one IBD segment when I compared him to my mother and me.

Salkin-DP:
1 76703639 81115460 3.9 1041
20 33262837 37312228 3.3 732

Salkin-DP's mother:
1 76703639 80555394 3.2 889

I've posted elsewhere that I've noticed .ru, .fi, .sw and .no in GEDmatch lists of my close matches. Since the segment we found is in the same place on Chr1 I assume it is IBD.
Salkin shared 2 segment's with my uncle but as I dont have them they could be IBS. Salkin did not have any >3cM segments shared to my maternal aunt.

Thanks Salkin,
dp :-)

PS: notice that I'm trying to change this thread from just looking for matching segments to highlight those that are IBD. [For this and the prior examples I kept a minimum of 3cM for segments and a minimum of 700 SNPs] If enough people contribute their matches to other Anthrogenica users --assuming that at least on one end there's close relatives in the comparison to get IBD-- eventually identical IBD segment matches might could be found between multiple pairs of users.

"The Geography of Recent Genetic Ancestry across Europe" by Peter Ralph*¤, Graham Coop*
Citation: Ralph P, Coop G (2013) The Geography of Recent Genetic Ancestry across Europe. PLoS Biol 11(5): e1001555. doi:10.1371/journal.pbio.1001555
...
If a pair of individuals have both inherited some genomic region from a common ancestor, that ancestor is called a ‘‘genetic common ancestor,’’ and the genomic region is shared ‘‘identical by descent’’ (IBD) by the two.
...
we define an ‘‘IBD block’’ to be a contiguous segment of genome inherited (on at least one chromosome) from a shared common ancestor without intervening recombination
...
We measure lengths of IBD segments in units of Morgans (M) or centiMorgans (cM), where 1 Morgan is defined to be the distance over which an average of one recombination (i.e., a crossover) occurs per meiosis. Segments of IBD are broken up over time by recombination, which implies that older shared ancestry tends to result in shorter shared IBD blocks.
...
Our simulations showed that we have good power to detect long IBD blocks (probability of detection 50% for blocks longer than 2 cM, rising to 98% for blocks longer than 4 cM), and a low false positive rate.
...
Pairs of individuals in this dataset were found to share a total of 1.9 million segments of IBD, an average of 0.74 per pair of individuals, or 831 per individual. The mean length of these blocks was 2.5 cM, the median was 2.1 cM, and the 25th and 75th quantiles are 1.5 cM and 2.9 cM, respectively. The majority of pairs sharing some IBD shared only a single block of IBD (94%). The total length of IBD blocks an individual shares with all others ranged between 30% and 250% (average 128%) of the length of the genome (greater than 100% is possible as individuals may share IBD blocks with more than one other at the same genomic location).
...
We find that the local density of IBD blocks of all lengths is relatively constant across the genome, but in certain regions the length distribution is systematically perturbed (see Figure S1), including around certain centromeres and the large inversion on chromosome 8 [36], also seen by [35]. Somewhat surprisingly, the MHC does not show an unusual pattern of IBD, despite having shown up in other genomic scans for IBD [35,37]. However, there are a few other regions where differences in IBD rate are not predicted by differences in SNP density. Notably, there are two regions, on chromosomes 15 and 16, which are nearly as extreme in their deviations in IBD as the inversion on chromosome 8, and may also correspond to large inversions segregating in the sample. These only make up a small portion of the genome, and do not significantly affect our other analyses (and so are not removed); we leave further analysis for future work.
...
Most detectable recent common ancestors lived between 1,500 and 2,500 years ago, and only a small proportion of blocks longer than 2 cM are inherited from longer ago than 4,000 years. Obviously, there are a vast number of genetic common ancestors older than this, but the blocks inherited from such common ancestors are sufficiently unlikely to be longer than 2 cM that we do not detect many. For the most part, blocks longer than 4 cM come from 500–1,500 years ago, and blocks longer than 10 cM from the last 500 years.

IIRC, the numbers under "self" for each group indicated that, the higher the number the less chance it shared segments with other nations.


BTW- try this self segment mapper .............I found a few people I match, corresponded with them and have found an association with them

I think that's the statistic under the "other" column. IMO "self" would be IBD segment average for matches within that country. Other would be the IBD average of someone in another country matching a person of that country.

Petr is participating in this project. He has shared with me many kit numbers which will take a while to process.
Among one of the kits I've run is a potential cousin match in genealogical time to my mother. Pity I didn't inherit part of the segment to prove it is IBD.

Thanks alot Petr.
You just never know where your matches are on GEDmatch :biggrin1:

Ilmari is also participating.
I have my first 2 way triangulation. So at least one segment has to be IBD. It is found in my mom, my paternal uncle, myself, as well as ilmari & his mom. Ther's a chance since it's on both sides of my family that it's a compound segment (http://www.anthrogenica.com/showthread.php?3667-Pedigree-Collapse-Calculator&p=64874&viewfull=1#post64874).

As mentioned earlier, 3 cM will be the normal lowest threshold. It may be lowered to 2.5cM if at least someone in my cluster has matched for 3cM or more to see if that generates a segment.
With regards to the segment in blue please see the following post (http://www.anthrogenica.com/showthread.php?3462-GEDmatch-Archaic-Matching&p=64803&viewfull=1#post64803) in the GEDmatch Archaic Matching thread.
Data on two segments, generated by lowering the SNP threshold to 600, have been removed. 700 will be the normal threshold, with 650 only used if at least one member in a user's cluster matches at least one in mine at the 700 SNP benchmark, and a segment is not otherwise generated.
Color coding of segments will generally only be used to highlight possible IBD segments that don't have their data on the same line. Boldtype will provide for the same line cases.
There has been almost no segment matches to my maternal aunt so her results are only given when found.

Stephen1986 is now participating in this thread. These are his results compared to my cluster. My uncle matched his brother and him on the same segment on Chr 19. I match the two brothers on a segment in Chr 12. My mother and me matched his brother on a segment of Chr 7 (albeit with <700 SNP). My uncle matched Stephen1986 on the same segment where my mother matched his brother. I'm not sure if I've run in a case where my uncle and mom match someone where I dont but they are cousins so that segment too could be IBD. That's 3 (>700 SNP) segments that are possibly IBD.

Li 2014 paper (http://www.plosgenetics.org/article/related/info%3Adoi%2F10.1371%2Fjournal.pgen.1004144)

I have noticed that 23andme kits have less matching segments with FamilyTreeDNA kits. This may be due to a case-be-case SNP testing difference (hopefully). I think this is why so few people have matched my aunt, even down to the 2.5cM level, when even going to 650 SNP threshold.
The averages are from my cluster and may not reflect the average kit(s) tested. See this POST (http://www.anthrogenica.com/showthread.php?3753-GEDmatch-kit-diagnostics&p=67248&viewfull=1#post67248) to see how I determined the averages
http://www.anthrogenica.com/attachment.php?attachmentid=3705&d=1422894953
In the case that it is due to a difference in companies I am contemplating making a separate chart for 23andme's, and only compare kits from the same companies to each other.
dp :-)
PS: In the case of 1 cM (for my aunt's kit) the average is < 150 SNPs so --according to Felix's Thought Logs-- such cannot be distinguished from noise.

For the FamilyTreeDNA kits the thresholds I've been using are fine at finding an average 4cM segment, below that length the segment needs to be SNP rich.

This less matching is only due to which version of 23andme , was it V3 or v4

This less matching is only due to which version of 23andme , was it V3 or v4
from what I've seen on Felix Thought Logs, 23andme V4's are not compatible with Ancestry or FamilyTreeDNA kits. She has a V4.

After some experimentation, and consultation with those higher than me, I have made a second tier threshold level.
In the chart I posted (http://www.anthrogenica.com/showthread.php?3753-GEDmatch-kit-diagnostics&p=67374&viewfull=1#post67374) in the GEDmatch Diagnostic Thread, 23andme kits split into two clusters. Kits of the cluster with <500k Token SNPs, when I compared them to this project, did not match any of my cluster's FamilyTreeDNA kits.
My aunt's 23andme's kit was one of those <500k kits, and her kit only matched at the 700 SNP threshold those kits that were also 23andme <500k kits.
For simplicity I have removed her kit from the cluster.
I have made a two way threshold. If your kit has less than 500k Tokenized SNPs on GEDmatch it will be run at 350 SNPs, 2.5cM. Otherwise, the comparisons will be made at the thresholds in the earlier spreadsheets. Instead of worrying about chip versions, I'll be running the diagnostic to dictate which thresholds to use.
The reason I had to do this is that at lengths that are for MRCA in historical times there is no problem. 700 SNPs works for >7 cM just like GEDmatch and other's use [a 100:1]. Since I am looking for older, shorter segments, SNP density / cM become relevant.
[click on the spoiler to see specifics]

After removing from the spreadsheet, the handful of segments that matched my aunt, there were 723 segments; and they had an average length of 3.83 cM.

The total number of SNPs of FTDNA & Ancestry kits run through the diagnostic found 21371815 SNPs in tokenization. Dividing by the number of kits yields an average SNP total of 577616.6216 per kit. Further dividing by 3338.31 cM (per half-identical auGenome) yields: 173.0266577 SNP/cM. The average 2.5 cM segment of these F & A kits contain 433 SNPs, for 3.0cM:519 SNPs and for 4.0:692 SNPs. I've been using 700 --with a drop down of 650 so about in line with average cM length of 3.83.
list item 2
The total number of Token SNPs of 23andme kits that had >500K is 12623246. That is an average of 788952.875 SNPs/kit. Over the auGenome this comes to 236.33 SNP/cM.
This gives a 2.5cM:581 SNPs, a 3.0cM:709 SNPs and a 4.0:945 SNPs. My thresholds have been right at the average of a 3.0cM segment for these kits.
list item 3
For the other 23andme kits, those for which tokenization found <500k SNPs, there were a grand total of 9650634 tokenized SNPs. This makes an average of 438665.1818 SNPs/kit. Dividing by the half-identical auGenome yields 131.4033693 SNPs/cM. That gives an average for a 2.5cM segment: 329 cM, for a 3cM segment of 394cM, for a 4cM segment: 526 SNPs and for a 5cM: 657 SNPs. Note that the SNP count / cM for the average segment I've been finding in this project, as aforesaid, is 3.83cM. The SNP density of these 23andme kits is too low, on average, to find this average segment. This is why, IMO, that I haven't been finding any matches for these kits.


Many places in the spreadsheet had had a [none] for the comparison to all three of my cluster's kits. This is not the case now. Also, many kits for which I hadn't posted results due to this have now been added. Also, some kits had not been run. This was especially the case when a person had more than one kit. If the other kit had a tokenized SNP count > 500k it too has been run and any additional segments have been added.
To see what threshold was used look at the border. If the section of a kit is bordered by green the kit had <500k SNPs.
Hope that covers things,
dp :-)

ilmara's and Wolf Warrior's segment matches involve more of the members in their clusters, as do others for reasons explained in the prior post. It is neat to be able to trace segments through multiple generations, on either end of the matches :-)

Anyone interested in comparing to my family cluster please PM me; or compare yourself to another Anthrogenica user's cluster and post your results in this thread. If people start doing this then comparisons between spreadsheets may yield a network of genetic connections between many user's clusters.

PS: Spreadsheet is updated as long as Editing Time allows, then a new post will be made.

brygian had a segment that matched two people in my cluster but was not found at the normal threshold parameters so I won't report it for the time being.

Anglecynn (http://www.anthrogenica.com/member.php?498-Anglecynn) is participating in this project. The longest segment match up to this point for anyone compared had been Wolfie's cousin to my uncle (with an 8 cM segment). Anglecynn's paternal grandmother is a one-to-many match for me on GEDmatch, at a GD=5. The match for me to his dad's gran is: 3 65197887 73345069 12.2 2105. The match is not on my maternal side, nor did my dad's brother match on this segment. On his end his father did not match on the segment. So I cannot use triangulation on the segment to determin IBD.
According to Wikipedia's statics on IBD, there is a 98% chance that the (unphased) segment is IBD. The MRCA has only a 5-20% chance of being in the last 6 generations. As I think I know my genealogy sufficiently I think it's safe to assume that the match is in the >80% that is more than 6 generations from us.
I will update the rest of the match information later next week.

The information is given in the broadest sense possible for compactness. Individuals results will vary. Such variances will be most noticeable in matching triangles that were found on both ends.

Threshold: Minimum segment length set to 3 cMs. Minimum size set at 700 SNPs.

Erik matches David Powell:
for 3 segments that have over 700 SNPs.
Erik matches David Powell's mother:
for 4 segments that have over 700 SNPs.

Comment: The segment lengths reported above vary from 3.0 cM to 3.9 cM. Two of the segments of match between my mother and Erik I don't have. I have one segment that they don't share, I suppose inherited from my father.

We could be 5th cousins, who knows!
