Studies on blood groups and other genetic markers in forest Nentzi: variation among the subpopulations.
A Samoyed-speaking group of fishers, hunters, and deer breeders numbering 1500 in total has been investigated. Seven territorial subgroups were examined with respect to 15 genetic systems. The presence of A2, cde, CwDe, Kpa, AK2, pc, Gmfb, and Gmfnb genes or haplotypes in low or moderate frequencies was observed. An unexpected finding was a deleted Gm(-;n;gb) phenotype in three siblings. Significant local genetic heterogeneity was observed with regard to AB0, Rh, Tf, PGM1, 6-PGD, and Gm systems. The summed genic heterogeneity was found to be highly significant (chi2 (132) = 663.70, P less than 0.001). Mean Fst was equal to 0.0228, reflecting variation among subpopulations dispersed in the forest-tundra area and living under conditions of partial isolation.
