Distribution of ABO and Rhesus phenotypes and genes in the population of Kursk region

The distributions of AB0 and Rhesus phenotypes and the corresponding genes in the population of Kursk oblast were studied. Based on these data, genetic differentiation of rural populations with respect to the d gene frequency was revealed. The differentiation was determined by the differences in the genetic and demographic structure of these rural populations. The frequency of homozygotes for the recessive gene d and the incidence of malformations affecting the children's viability increased with an increase in the inbreeding level of a population. Genetic distances between the population of Kursk oblast and other populations were estimated.
