[Population genetic characteristics of highland and meadow Mari. Genetic markers]

ABO blood groups; serum proteins, including transferring (Tf), group-specific component (Gc), proteinase inhibitor (PI), and haptoglobin (Hp); and erythrocytic enzymes, including acid phosphatase (ACP1) and phosphoglucomutase (PGM1), were studied in two ethnic groups from the Marii EI Republic-Highland and Meadow Mari. The size of populations examined were 111 and 140 individuals, respectively. Data on frequency distribution of phenotypes and genes are reported, and the two populations are compared with respect to allelic frequency. To assess the subdivision of the population, GST was used. Its value was 0.0041.
