THE NANAI CLAN SAMAR: THE STRUCTURE OF GENE POOL BASED ON Y-CHROMOSOME MARKERS1

Members of the Nanai clan Samar reside in the Gorin area of the Khabarovsk Territory. Their gene pool was studied using the SNP markers of the Y-chromosome. The major haplogroup, occurring in more than 83% of clansmen, is the northern Eurasian haplogroup N1c1-M178. Four other haplogroups are С*-М130, I*-M170, J2a1а-M47, and O2-P31. The most frequent haplogroup, N1c1-М178, indicates mostly Tungus origin of the Samar clan; other haplogroups detected by complete sequencing, such as the minor haplogroup C3*-M130, reveal ties with native populations of the Amur basin. Genetic distances and their multidimensional scaling demonstrate marked affinities of Samar clansmen with Yakuts, Khakas, and certain groups of Buryats, suggesting a common origin. Nanai of other regions are much further from the Samar.
