Abstract
Purpose
. The paper continues a series of articles devoted to the paleogenetic study of the Late Medieval population from the West Siberian forest-steppe zone. The aim of the study is to obtain and analyze the first data on the Y-chromosome lineage diversity of the population that formed the Abramovo-10 burial ground in the central part of the Baraba forest-steppe (16
th
– 18
th
centuries AD).
Results
. Data on the structure of 18 Y-chromosome samples (male individuals) from the burial ground of the Siberian Tatars Abramovo-10 were obtained. Phylogenetic and phylogeographic analysis of the studied lineages was carried out. Three phylogenetic clusters were identified in the studied series: N-VL67/N1a2CTS6380>>VL67 (N = 13, or ~ 72 % of the sample), Q-L56/Q-M346/Q1a2 (N = 4, or ~ 22 %) and R-M198/R1a-M198 (N = 1, or 5.5 %).
Conclusion
. The obtained results suggest that the basis of the male gene pool in the studied group consists of Y-chromosome lineages that spread across the region during the Turkification in the Middle Ages, as well as older components common to ethno-culturally contrasting populations of the Western Siberia. The phylogeographic structure of the Y-chromosome pool, which is close to the modern one, was formed earlier than the features of the mtDNA gene pool, apparently due to the patrilocality of the studied group. During the period of the intensive Caucasian population migration to the region, the main features of the male gene pool remained almost unchanged for significant part of the Baraba Siberian Tatars.
