Analysis of Genetic Diversity of North Eurasian Populations Using Autosomal Microsatellite Loci

The paper presents the results of analysis of the gene pools of several North Eurasian ethnic groups (Buryats, Evenks, Altaians, Russians, Kyrgyzes, Tuvinians, Tatars, and Ukrainians) examined using a panel of autosomal microsatellite markers (D4S397,D5S393, D7S640, D8S514, D9S161, D10S197, D11S1358, D12S364 and D13S173) mapped on different chromosomes and represented by the (CA)n dinucleotide repeats. In the group of populations examined the proportion of genetic variability at microsatellite loci explained by interpopulation differences was about 2.5%, while genetic differences between the individuals within a population accounted for 97.5% of this variability. Analysis of genetic relationships among the populations revealed substantial differences between the populations belonging to the Indo-European and Altaic linguistic families in gene diversity at microsatellite loci.
