Abstract
Chi-spuare contingency table analysis of phenotypic (genotypic) and gene frequencies of erythrocyte and blood serum groups and enzymes in a group of hunters and fishermen revealed heterogeneity within the population studied. Four out of 12 loci were found to be involved in the process of differentiation into 2 local subgroups (subpopulations). No statistical differences have been observed between samples arbitrarily representing 3 generations. The whole population still evidently preserves the state of the stability. Traditional migration from adjacent populations close to Nganasans by language and culture has made an important contribution into heterogeneity found in nganasans.
