Those of European descent, lets see if we can figure out this South Asian thing...

[SwampThing27]

I really would like to pin down the South Asian (Indian) component in those of us from British descent. As many have noticed, Northwest Europeans tend to have more of this component than other Europeans and it is something that has interested me since the first time I uploaded my data to Gedmatch. Note that I show ZERO South Asian on 23andme's ancestry composition and also only show European on FTDNA's MyOrigins, but I will start by posting my South Asian scores for various Gedmatch calculators as well as my result from DNAtribes. All of these numbers are higher than the averages for my respective ancestral populations. (British, French, German, Dutch)

Harapaworld: 1.27%
Eurogenes K13: 3.25%
Dodecad V3: 2.45%
MDLPK 23b: 1.67%
DNA Tribes: Gangetic North-Central India 6.4% and Brahmin Andhra Pradesh India: 1.7%
23andme: 0%
FTDNA: 0%

Would anyone else be interested in putting forth theories as to why some of us have these higher numbers, and also why they don't show on 23andme? I originally suspected that it was simply an ancient remnant found in Northwest Europeans, kind of like a sticky spot that has just continued to mix over and over in that population and if anyone else feels the same than lets discuss that. Any input at all is appreciated.

I am maybe 15%-20% English/Irish/Scottish and pretty low on the South Asian. The rest is Continental West Europe or unknown. I am excluding Southeast Asia and Southwest Asia as different and using South Indian as the number where the calculator calls it that:

Geno 2.0 - 0%
FTDNA Origins - 0%
MDLP K23b - 0%
Eurogenes K13 - 0.64%
Eurogenes EUtest V2 K15 - 0.24%
Dodecad K12b - 0.45%
Dodecad World9 - 0.67%
Dodecad Globe13 - 0.76%
HarappaWorld - 0.22%

I think Gedrosian is the real connection. The South Asian components are usually a mix of ANE, ENF, ASI, and Oceanian. Since Archaic admixture can show up as ASI or Oceanian (especially Denisovan and Oceanian), it could be that which is gravitating towards South Asian in non-South Asians. Europeans already have ANE/ENF. There might be a connection between primitive WHG/ANE and Oceanian or even ASI.

My Gedrosia or similar results from those calculators that call it out:

Dodecad K12b - 6.31%
MDLP K23b - 4.40%
HarappaWorld - 7.15%

Romany ancestry could be the source of the South Indian.
My father is the opposite...he has south Indian on 23andme and near eastern on myorigins. He is a unique case though because he has known ancestors from India...2.3% of ancestry. He also has currently unknown romany ancestry as he shares the same autosomal segments with individuals from Britain, Sweden, and Romania...all having Romany ancestors.

Could the Baloch/south Indian admixture in Europe be linked to the Indo-Europeans or Steppe Migrations ?

[Baltimore1937]

I have not downloaded my raw data. I only took the FTDNA and Ancestry.com autosomal tests. FTDNA gives me 100% European. Ancestry gives me 98% European, plus 1% Caucasus and "<1%" South Asian. I notice that a few matches at Ancestry with trace South Asian seem to point to Wales. I also recall a match with S-A with someone with old Maryland connections. But I didn't try to keep track of all that on paper, etc.

Well, in that case perhaps there isnt anything ancestrally specific about a higher South Asian score, since you and your brother obviously have the same ancestors. Maybe its just the way the DNA combined on some chunk of SNPs yo give a South Asian vibe. Or maybe a chunk that your brother inherited that you didnt.
