- Abstract
The genetic diversity in two ethnic groups of the central part of the North Caucasus (Balkars and Karachays) using 50 diallelic loci in the non-recombining region of the Y chromosome was analyzed. For the first time, an analysis of distribution of frequencies of Y-chromosome haplogroups in Balkars considering different subethnic groups (Baksans, Chegems, Kholams, Bezengiyevs, and Malkars) was conducted. The major Y-chromosome haplogroups in the studied groups of Balkars and Karachays were G2a-P16 and R1a- Z2123. In addition, for a better understanding of genetic relationship between the male lineages in the studied populations and other populations of the Caucasus, we performed an analysis of R1a-M198 subhaplogroups in 22 populations of this region. The principal component analysis demonstrated that a greater difference was observed between Kholams and the other Balkar subgroups. According to the F analysis, Chegems, for which the prevalence of haplogroup R1b-M478 (32.2%) was reported, demonstrated the maximum difference from the other subpopulations of Balkars and Karachays.
