Abstract

Seven clans of north-western Bashkirs (total sample size N=230) were analyzed by 49 Y-chromosomal SNPs and 17 STRs. These clans belong to the two ethnographic groups – nizhnebelska and northern – however, the genetic structure of the clans does not follow this ethnographic classification. Paternal pool of each clan carries a predominant haplogroup. In clan Girey haplogroup I1-M253 predominates (frequency is 75%); this haplogroup is typical for Scandinavia but is also present in Finno-Ugric speakers along Volga river. Haplogroup G1-M285 is frequent (60%) in clan Kangly, indicating its southern origin. Haplogroup R1a predominates in clan Unlar (100%) and clan Balyksy (77%), revealing their common origin with north-eastern Bashkirs whose paternal pool consists mainly of this haplogroup. The major haplogroup (44%) for clan Eney is N3a2, which is East Siberian branch of haplogroup N3-M178. N3-M178 – though its another branch N3a4 - is also frequent in clan Elan. The same branch comprises 90% of the gene pool of the clan Uran. This N3a4 branch is common in western group of Finnic language subfamily, but its specific subbranch arose more than 4,000 years ago and is still present in the Ural region; thus, it might be part of the gene pool of Proto-Finno-Ugric population. Two out of seven genetic portraits of Bashkir clans fit well into the ethnographic hypotheses of their origin. Two other genetic portraits does not contradict the corresponding ethnographic hypotheses, but the remaining three indicate the predominance of the genetic legacy of the assimilated Finno-Ugric speaking populations in present day Turkic speaking north-west Bashkirs. The genetic similarity between north-west Bashkirs and Finno-Ugric populations was revealed also by the multidimensional scaling analysis based on frequencies of all studied haplogroups.
