The Paleogenetic Study of Bertek-33, an Afanasyevo Cemetery on the Ukok Plateau, the Altai Mountains

Abstract

We present the results of a paleogenetic analysis of bone samples representing seven adult individuals from Bertek-33—an Afanasyevo cemetery on the Ukok plateau, in the Altai Republic, Russia. The fi ndings are interpreted with reference to archaeological and anthropological data. Four systems of genetic markers were analyzed: mitochondrial DNA, polymorphic fragment of the amelogenin gene, autosomal STR-loci, and Y-chromosomal STR-loci. Genetic results indicate the dominance of Western Eurasian mtDNA haplogroups (T, J, U5a, K, H) and the homogeneity of the male gene-pool represented by variants of the Y-chromosomal haplogroup R1b. Data on mtDNA, Y-chromosome, and individual autosomal markers attest to the Western Eurasian affi nities of this group. The sample falls within the mtDNA and Y-chromosomal diversity of the Afanasyevo population of southern Siberia. Possible kinship between the individuals buried at Bertek-33 is discussed. Also, we address theoretical issues such as the accuracy of comparisons and the interpretation of genetic data with regard to cultural features.
