Sargat_IA KAZ_Mereke_MBA 0.135±0.017 kra001 0.301±0.007 RUS_Sintashta_MLBA 0.499±0.023 TKM_Gonur1_BA 0.066±0.015 chisq 8.872 tail prob 0.262001 Full outputThat's a better statistical fit and also, I'd say, a more realistic model, at least in terms of distal ancestry proportions. Note that Nganasan-related ancestry makes up 30% of the genome-wide genetic structure of the Sargat samples, which again corroborates the view that Uralic languages were spoken within the Sargat horizon. Update 28/04/21: This is the best qpAdm model that I could find for Sargat_IA, at least in terms of the chisq and tail prob. It shows that the Sargat population was in large part very similar to that of KAZ_Pazyryk_IA.
Sargat_IA KAZ_Mereke_MBA 0.032±0.016 KAZ_Pazyryk_IA 0.698±0.016 RUS_Sintashta_MLBA 0.236±0.021 TKM_Gonur1_BA 0.034±0.014 chisq 2.023 tail prob 0.958561 Full outputIt's missing kra001, because KAZ_Pazyryk_IA packs enough kra001-related ancestry for the job.
KAZ_Pazyryk_IA KAZ_Mereke_MBA 0.144±0.018 kra001 0.429±0.008 RUS_Sintashta_MLBA 0.378±0.026 TKM_Gonur1_BA 0.049±0.018 chisq 8.899 tail prob 0.259983 Full outputThe fact that KAZ_Pazyryk_IA can be modeled with significant kra001-related ancestry isn't surprising, considering that its territory was located in Siberia. However, my model doesn't necessarily prove that the Sargat population was largely or even partly of Pazyryk origin. Indeed, N-L1026 hasn't yet appeared in any Pazyryk remains. See also...
