Haplogroup Q

Q-M242 (mutational name) is the defining (SNP) of Haplogroup Q (Y-DNA) (phylogenetic name). In Eurasia, haplogroup Q is found among the ancient Afontova Gora specimens, and Indigenous Siberian populations, such as the modern Chukchi and Koryak peoples, as well as some Southeast Asians, such as the Dayak people. In particular, two groups exhibit large concentrations of the Q-M242 mutation, the Ket (93.8%) and the Selkup (66.4%) peoples. The Ket are thought to be the only survivors of ancient wanderers living in Siberia. Their population size is very small; there are fewer than 1,500 Ket in Russia. 2002 The Selkup have a slightly larger population size than the Ket, with approximately 4,250 individuals.
