Y-Chromosome as a Tool for DNA-Identification and Determination of Ethno-Territorial Origin

Genetic diversity of a large number of populations is analyzed using various Y-chromosome markers. Genotyping of a wide range of novel highly informative SNP and YSTR markers shows that most of the Y-chromosome haplogroups can be divided not only into ethnically specific lineages but also into narrower sublineages and clusters of haplotypes. A significant extent of population and interethnic genetic differentiation is revealed. Most ethnic gene pools are characterized by the predominance or even complete dominance of specific SNPs across all major haplogroups, that is highly promising for the application in ethnic identification of biological samples of males.
