Compositions and frequencies of Y-chromosome haplogroups have been studied for Northern and Southern Altaians. As a result eighteen haplogroups: C3хM77, С3с, DxM15, E, F*, J2, I1a, I1b, K*, N*, N2, N3a, O3, P*, Q*, R1*, R1a1 and R1b3 have been revealed in Altaian gene pool. The presence of Caucasoid and Mongoloid components, as well as of ancient genetic substrate, marked by the corresponding Western and Eastern Eurasian haplogroups, define the structure of Altain gene pool. R1a1 is the most widely distributed haplogroup in both ethnic groups, which comprises about 53% for Southern and 38% for Northern Altains. This haplogroup is evidently concerned with eastward settling of early Indo-Europeans and marks a Caucasoid component in the gene pools of South Siberian populations. Haplogroup Q* occupies the second place as regards frequency and as haplogroup K* it is considered as a paleo-Asiatic marker. The presence of these haplogrous is evidently concerned with Ket and Samodian contributions to Altaian gene pool. The presence of lines N2 and N3a is probably explained by the contribution of Finno-Ugric tribes assimilated by ancient Turkic populations. Haplogroups С3xM77, C3c, N* and O3 are considered as genetic contribution of Central Asian Mongoloid groups, probably reflecting the latest contribution of Mongolian migrants from the territories of present-day Tuva and Mongolia. The results of factor, variance and cluster phylogenetic analyses testify for significant genetic differentiation of Northern and Southern Altains. They were found to differ not only in haplogroup composition but also in inner haplotypical structure.
