Triangulation does NOT mean IBD - Blog comment by tewilso - 25 Feb 2018

Update: By analyzing all pairs, I have two cousins that triangulate (GEDMatch one-to-one comparisons) with a potential cousin on Chr 1 (all separate pairs match on this same segment.) The known cousins are my 5th-6th cousins, the potential cousin would be our eighth cousin. Ditto on another segment (Chr 18) but ...

Triangulation does NOT mean IBD - Blog comment by lkessler - 18 Feb 2018

tewilso: What I can’t tell from your example is who is matching who. Unfortunately, and especially for smaller segments under 7 cM, chance matches can happen because the companies are comparing both parental chromosomes of one person with both parental chromosomes of another chromosome. And that is at ...

Triangulation does NOT mean IBD - Blog comment by tewilso - 18 Feb 2018

The GEDmatch Relationship Tree tool - Blog comment by lkessler - 25 Jan 2018

Joe: We're just beginning see the development of good tools to analyze all this DNA stuff. GEDmach is doing a great job providing new ideas like this, and it's great when there's one that can help us make sense out this nonsense.

The GEDmatch Relationship Tree tool - Blog comment by jbissett - 25 Jan 2018

Hi Louis, Once again you have provided a most valuable explanation of an existing GedMatch feature that so far I had not understood or used. My maternal half-brother only shows 2 X-dna matches for unknown cousins. I ran the first one (only 8.2 cms atDna and 7.5 cms X-Dna) and I am pleasantly surprised to find ...

Revisiting Missing A-B Matches - Blog comment by lkessler - 19 Jan 2018
