The proportion of Corded Ware was 62% in Central Russians and 61% in Mordovians, but both obviously had lower Nganasan.

Also in the G25 model below, out of the ancestry of Udmurts that is not from Krasnoyarsk_BA, about 82% is from Yamnaya (but the model doesn't have an EHG source, and maybe Udmurts have extra EHG that is not from Yamnaya):

How much Mongoloid is that Krasnoyarsk sample? It sure isn't Andoronvo since those were pretty much whites. Why not use Ymiyakhtakh Yakutia instead?

Oh sorry, I had WHG in my sources at first, but I forgot to add it back. Here's the models I ran:

(I use a modified version of Michał's CVXPY script, and I have shell functions for quickly selecting lines from G25 datasheets.)

Krasnoyarsk_BA is closer to Nganasans. This is a PLINK PCA based on the Reich dataset, where some of the samples from KolymaRiver_LN and CentralYakutia_LN are called RUS_Yakutia_Ymyiakhtakh_LN in G25:

Like 100% Mongoloid it seems:

Interesting. Looks like it was some kind of indigenous inhabitant of Siberia, unlike the Andronovans. I wonder if modern Siberian Turkics/Altaians can be understood as a mix of the two. They are heavily R1a-Z93 but autosomally 60-75% East Eurasian depending on the group.

By the way, why can't anyone convert the Yunusbayev data to G25 format? I emailed David weeks ago - no response. On Anthrogenica no one has replied to my thread either. Is it that difficult? I need the Tajiks and Kumyks from that old-ass study. :ohwell:

Do you know why Udmurts on Tambets using qpAdm are 30% Mongoloid whereas Udmurts on G25 are like 25-26% Mong on average?

Interesting, I heard a rather expert user on Anthrogenica mention that Udmurts also have some Iran_N or extra CHG so I'm surprised they don't score any in G25 or that Tambets qpAdm model.

Prolly their Siberian reference is not 100% East Eurasian.

They score that even on Gedmatch. Their West Asian average is double that of ethnic Russians.

It's not qpAdm but qpGraph. And there was no Iran_N or CHG source in their qpGraph model.When I recreated the qpGraph model of Tambets 2018 in ADMIXTOOLS 2, Udmurts only got 26% Nganasan, but it could be because I used different samples:

Edit: But when I used `maxmiss=1`, Udmurts got 32% Nganasan. (By default, ADMIXTOOLS 2 discards each SNP which is missing from every sample in a population, but `maxmiss=1` discards no SNPs.)

Are you even tried qpGraph only with modern samples? I want to see such model, for some VURs could be.
