Scytho-Sarmatian genetics

[TheForeigner]

What do genetic studies say about the genetic makeup and relatedness with other peoples of Scythians and Sarmatians?

[Pahli]

West Eurasian Scytho-Sarmatians were around 10% Mongoloid and can be set up to be 2/3 Baltic and 1/3 Afghan Pashtun or 50% Baltic and 50% Tajik Pomiri (East Iranian minority). This sample is from Volga, 300 - 200 B.C.

This is believed to be Scythian in Eastern Hungary, around 900 - 800 B.C:

The difference between the two samples is the greatly reduced Anatolian farmer admixture in the Volga sample and slightly reduced West Asian admixture in the Hungarian one, otherwise they are pretty much similar in NE European and Mongoloid admixture.

[TheForeigner]

How did they get Afghan or Tajik admixture or the Mongoloid?

Because they had some admixture from native Central Asian farmers which Tajiks and Afghans share most of their ancestry from. I assume they would have been similar to modern Balochis or Brahuis. The Mongoloid most likely comes from the Altai region, which was overlapped by the Andronovo culture.

How come they were so tall and light pigmented then?

How come they were so tall and light pigmented then?

They were dominantly Caucasoid of NE European and West Asian admixture, both passes on genes for light pigmentation, and they had relatively low South Asian (5%) and Mongoloid admixture (10%) which didn't really affect them. As for being tall, I guess it comes with the NE European admixture, although I'm 190cm myself and Kurdish, so I'm not sure how that works.

South Asian admixture too? How the hell would they get that?

South Asian admixture too? How the hell would they get that?

Native Central Asian farmers were dominantly CHG + some South Asian (I assume 20 - 30%) thats where they got it from.

How did they get Afghan or Tajik admixture or the Mongoloid?

Slowly but continously since the Bronze age.
