Variability and identification power of 60 X-chromosome in two native Siberian populations

Genetic diversity of 60 X-chromosome single nucleotide polymorphisms (XSNPid panel) in populations of Siberian Tatars and Tuvinians is described. A close spectrum of allele frequencies and a low level of their genetic differentiation (G st = 0.021) is revealed. High discriminating power of the XSNPid panel in populations under study is demonstrated. The random matching probability (MP) of multilocus genotypes in males is 1.12 × 10–18 in Siberian Tatars and 7.77 × 10–16 in Tuvans. In females, MP is several orders of magnitude lower: 1.51 × 10–25 in Siberian Tatars and 1.83 × 10–23 in Tuvinians.Читать в источнике
