Abstract

The structure of the Buryat gene pool has been studied based on the composition and frequency of Y-chromosome haplogroups in eight geographically distant populations. Eleven haplogroups have been found in the Buryat gene pool, two of which are the most frequent (N1c1 and C3d). The greatest difference in haplogroup frequencies was fixed between western and eastern Buryat samples. The evaluation of genetic diversity based on haplogroup frequencies revealed that it has low values in most of the samples. The evaluation of the genetic differentiation of the examined samples using an analysis of molecular variance (AMOVA) shows that the Buryat gene pool is highly differentiated by haplotype frequencies. Phylogenetic analysis within haplogroups N1c1 and C3d revealed a strong founder effect, i.e., reduced diversity and starlike phylogeny of the median network of haplotypes that form specific subclusters. The results of a phylogenetic analysis of the haplogroups identified common genetic components for Buryats and Mongols.
