Re: FamilyTreeDNA provides Y-DNA haplogroups from Family Finder autosomal tests

Hi Centropol ? I don¡¯t think the problem of false positive matches will affect the so-called ethnicity reports as they are working out in a different way and are not reliant on detecting IBD (identical by descent) segments. ? Regardless of the problems with the smaller matches, the MyHeritage database is now a very good size with over 7.7 million people now tested: ?
? Most people are starting to get a few good matches there. ? Debbie ?

Subject: Re: [R1b-U106] FamilyTreeDNA provides Y-DNA haplogroups from Family Finder autosomal tests? That is very interesting. If the rate of false positives "child-only matches" is so high then I also wonder how it affects the ethnic origin estimated in MH, although for my mother the estimate matches reasonably well the family history, although it still shows anomalies like a quite significant Anglo-Saxon ancestry. I did not manage to test my father so I estimate his ancestry by comparing my mother's and mine, basically doing a primitive phasing.
The comparison of different chips gives a very concerning information, frankly. I tested myself and my mother at FTDNA and later transferred to MH.
Thank you again Debbie.
