Central/South Asian DNA– Another Vendor, Another Twist in the Path

Getting new autosomal DNA results always seems to be one step forward and at least two steps back, in terms of any consistency with the previous results. Having already tested with 23andme and AncestryDNA, I got an offer from the third such vendor of autosomal DNA for a $39 report and family finder matches using the same DNA data. So I took the bait, and found that the good news is that all three agree that my European DNA is 98%. Otherwise, though, there is very little consistency. as FamilyTreeDNA finds no Iberian, Scandinavian, or Jewish elements within the European portion, unlike the last test. As for the non-European aspect, this test finds subSaharan African at a trace level like the last, but unlike either it reports 2% Central/South Asian admixture.

Which takes us back to the Roma or East Indian scenario about possible non-European roots of Pell Meller “mulattoes.” Reviewing the three major autosomal vendors and the four models provided by Gedmatch: FTDNA, AncestryDNA, and 23andme all agree that the European percentage is roughly 98% but vary considerably in the breakdown of European DNA. As for the non-European, none finds any Native American, AncestryDNA finds Central Asian and West African in equal trace amounts of under 1%, FTDNA finds twice as much Central Asian as African (and the latter is mostly South rather than West Africa), and 23andme finds 1.9% combined African and no Asian. Of the four models in Gedmatch, Harappaworld finds about six times as much Asian in various categories as African; Eurogenes finds three times as much Asian as African; MDLP and Dodecad both find four times as much Asian as African; all four show percentages of both far greater than the three main vendors. No model finds a significant amount of Native American. The Asian scores raise the question of whether European/Asian admixture occurred in the New World in the last 400 years, or earlier.
