Abstract: Study of Y-chromosome polymorphism with consideration of the genealogical structure provides information about the history and the fine structure of gene pool, and it can help identify major patterns of variation in gene pool, determination of migration routes, and genetic boundary between the relatively homogeneous gene pools.
The study was performed on the Kazakh tribe of Argyn, which are included in the three “Juz” (ethno-territorial entities of Kazakh tribes) in the "Shezhire" system of Kazakhs. The Shezhire system characterizes the tribal structure of the Kazakh people, which was the ethno-social basis of social organization. It is therefore important to examine the association of Y-chromosome variability with the genealogical structure, and clarify the relationship between biological and social kinship.
We analyzed 40 SNP and 17 STR Y-chromosomal markers. In the study, besides the descendants of Argyn (sample size N = 287), 14 tribes of Kazakhs and 12 tribes Mongolians (in all N = 2186) were analyzed. In the tribe of Argyn, twenty haplogroups were identified, among which there were one major haplogroups - G1a - P20 (71%) and three minor haplogroups R1a* - M198(xM458) (6%), C3c - M48 (5%) and C3* - M217(xM48) (3%). Other haplogroups represent less than three percent.
We calculated the genetic distances and plot multidimensional scaling, comparing the gene pools of the studied genus with other tribes of the Eurasian steppe from the frequencies of haplogroups. Tribe Argyn took on graph an isolated position, demonstrating the absence of genetic links with other Kazakh tribes.
