Genetic polymorphisms in a rural Osetian community.

Abstract

Data are presented on ABO, Rhesus, MNSs, P, Duffy, Kell and Kidd blood group polymorphisms in the Dzhava district, located on the southern slopes of the Main Caucasian Mountain Range. The gene frequencies, compared with those in other Osetian populations and neighbouring ethnic groups of the Caucasus, show general similarity. An exception to the general pattern is presented only by the P blood group system, where the frequencies of the alleles are significantly different form those observed in the neighbouring populations.
