A new stage in the paleogenetic study of the Odino culture populations includes the analysis of a series of paleoanthropological samples from four Odino burial grounds: Sopka-2/4a, Ust-Tartas-2, Tartas-1, and Preobrazhenka-6. The total number of the expanded Odino series includes more than 200 paleoanthropological samples (individuals). The research plan includes a significant increase in the number of mtDNA samples (up to ~150 samples) and obtaining data on the male genetic variability of the Odino population (~50 samples of the Y chromosome). In this paper, we present the results of the analysis of an extended mtDNA sample series from the Sopka-2/4a burial ground. The study covers paleoanthropological samples from 88 individuals. The structure of mtDNA lineages and their phylogenetic position were defined for 60 individuals (~68 % of the initial sample). Twenty mtDNA haplotypes were identified among the studied samples. The Odino population is characterized by a mixed composition of the mtDNA gene pool, represented by the East Eurasian (A8, A10, C, D, Z) and West Eurasian (U2e, U4. K, HV6, I) haplogroups. New data confirmed the previously obtained preliminary inferences about the dominance of the East Eurasian components in the gene pool and the high role of autochthonous components marking genetic continuity with the previous population groups in the region (A10, D, Z, U2e haplogroups) in the process of formation of the Odino population. At the same time, new components associated with the influx of a genetically contrasting population (K, HV6 haplogroups) into the Baraba forest-steppe were identified in the extended mtDNA series. Obviously, the interaction of autochthonous and migration-related genetic components, most likely, was the mechanism for the formation of genetic features of the Odino population. New genetic data are discussed here in the context of current data on directions of external cultural relations of the Odino population from the Baraba forest-steppe.
