Abstract:Y-chromosomal haplogroups composition and frequencies were
analyzed in Northern and Southern Altaians. In the gene pool of
Altaians a total of 18 Y-chromosomal haplogroups were identified,
including C3xM77, C3c, DxM15, E, F^*, J2, I1a, I1b,
K^*, N^*, N2, N3a, O3, P^*,
Q^*, R1^*, R1a1, and R1b3. The structuring nature
of the Altaic gene pool is determined by the presence of the
Caucasoid and Mongoloid components, along with the ancient genetic
substratum, marked by the corresponding Western and Eastern Eurasian
haplogroups. Haplogroup R1a1 prevailed in both ethnic groups,
accounting for about 53 and 38% of paternal lineages in Southern and
Northern Altaians, respectively. This haplogroup is thought to be
associated with the eastward expansion of early Indo-Europeans, and
marks Caucasoid element in the gene pools of South Siberian
populations. Similarly to haplogroup K^*, the second
frequent haplogroup Q^* represents paleo-Asiatic marker,
probably associated with the Ket and Samoyedic contributions to the
Altaic gene pool. The presence of lineages N2 and N3a can be
explained as the contribution of Finno-Ugric tribes, assimilated by
ancient Turks. The presence of haplogroups C3xM77, C3c,
N^*, and O3 reflects the contribution of Central Asian
Mongoloid groups. These haplogroups, probably, mark the latest
movements of Mongolian migrants from the territory of contemporary
Tuva and Mongolia. The data of factor analysis, variance analysis,
cluster analysis, and phylogenetic analysis point to substantial
genetic differentiation of Northern and Southern Altaians. The
differences between Northern and Southern Altaians in the haplogroup
composition, as well as in the internal haplotype structure were
demonstrated. [ABSTRACT FROM AUTHOR]
