Abstract: | In order to investigate the genetic history of autochthonous South Siberian populations and to estimate the contribution of
distinct patrilineages to their gene pools, we have analyzed 17 Y-chromosomal binary markers (YAP, RPS4Y711, SRY-8299, M89, M201, M52, M170, 12f2, M9, M20, 92R7, SRY-1532, DYS199, M173, M17, Tat, and LLY22 g) in a total sample of
1,358 males from 14 ethnic groups of Siberia (Altaians-Kizhi, Teleuts, Shors, Tuvinians, Todjins, Tofalars, Sojots, Khakassians,
Buryats, Evenks), Central/Eastern Asia (Mongolians and Koreans) and Eastern Europe (Kalmyks and Russians). Based on both,
the distribution pattern of Y-chromosomal haplogroups and results on AMOVA analysis we observed the statistically significant
genetic differentiation between the populations of Baikal and Altai–Sayan regions. We suggest that these regional differences
can be best explained by different contribution of Central/Eastern Asian and Eastern European paternal lineages into gene
pools of modern South Siberians. The population of the Baikal region demonstrates the prevalence of Central/Eastern Asian
lineages, whereas in the populations of Altai and Sayan regions the highest paternal contribution resulted from Eastern European
descent is revealed. Yet, our data on Y-chromosome STRs variation demonstrate the clear differences between the South Siberian
and Eastern European R1a1-lineages with the evolutionary ages compatible with divergence time between these two regional groups. |
