Diversity of the 16126C types of mitochondrial DNA in eastern slavs from Magadan

: Nucleotide sequences of the 16126C types of hypervariable segment I from the major noncoding region of human mitochondrial DNA in eastern Slavs from Magadan (N = 19) were analyzed. The mitochondrial DNA sequences were subsumed within three Caucasoid-specific mitochondrial haplogroups, T, J, and JT*. Haplogroup T in eastern Slavs proved to be the most rich in different hypervariable segment I types (nucleotide diversity 1.03%). Haplogroup J was remarkably less heterogeneous (0.28%). Data on the frequency distribution of haplogroup T and J subgroups among eastern Slavs in comparison with some other populations of Eastern Europe are presented.
