Differentiation into European components by using admix-n and convex optimization

This Chuvash is probably because of Saami, but I don't know what kind of result would this sample get with the world spreadsheet.
Siberian could point to Saami or to native Amerindian. West Asian (Turkic) can also appear in place of Amerindian.

I think it’s unlikely to be Amerindian for me. It’s possible it could be from other immigrants to London. But it’s only 1.88% Siberian and I don’t really know if that’s noise. I get 7.51% West Asian.

In G25 you don't get West Asian, only Siberian and traces of Papuan and Amerindian.

...or Cossack/Karelian.

There's something in Global25 which apparently makes it difficult for the software to decide whether Karelian i.e. Baltic Finn is a Kuban Cossack or not.

Actually 'West Asian' might be from my Irish side as the Irish average on K13 is 6.32. I hadn't noticed that.

Cossacks have Turkic admix from various Steppe populations like Tatars. It looks that G25 can't properly separate Turkic from Uralic, Siberian and Amerindian populations.
But some Turkic and Uralic populations are related.

Do you know how much approximately Turkic do Kuban Cossacks have?

well most of their "Asiatic" ancestry is rather Uralic. South Russia was populated from Central Russia and Ukraine rather recently. In the case of Central Russia some of them had strong Finno-Ugrian admixture. So these Cossack sample from Kuban clusters closest with Russians in Kostroma and Tver on Global25. He does not seem to have significant Tatar admix rather some strong Finno-Ugrian ancestry from the Volga region. Other Cossack samples probably have actual Tatar or Caucasian ancestry but this must be looked individualy and many if not most samples will lack such kind of admix. Other Cossack samples from Kuban will cluster more with Ukrainians.

Uralic can overlap with Turkic, Cossacks spoke Tatar in 19 century. I doubt there is strong Finno-Ugric admix in Central Russia, it is very strong in northern and eastern regions. I know, phenotypes do mean much, but If you are interested you can see phenotype of one person of Kuban Cossack ethnicity in Wikipedia about Kuban Cossacks, looks like fully Turkic, very strong East Asian features.

With Central Russia i mean here the Volga region too from where settlers and local Cossacks were send to South Russia. The Volga region and espcieally regions around the Ural have strong Finno-Ugrian admix much less so regions around Moscow, Vladimir and Tver.

I am not aware yet of any modern day Slavic Cossack sample clustering with Tatars and phenotypically they look just like other Russians from South Russia. Not even most Tatars in Tatarstan look fully "turkic" so i don't really understand how someone can see Kuban Cossacks as looking "fully turkic". They have more non-Russian admix for sure but in many cases it is rather of Vlach, Central Euro/Ukrainian/Polish, Volga Finnic or Caucasian than Tatar.

Wondering if you could do my breakdown? Much thanks!
