Genetic structure of isolated group of indigenous population in Northern Siberia - Nganasans (Tawgiytsi) from the Taymyr Peninsula. IV. Familial analysis of blood groups

Family analysis of ABO, MNSs, Rhesus, Duffy and Kell (Kp) in 50 families of nganasans was carried out. Segregation deviations were found in those families where the variation among the children was widest. The proportion of children from unmarried persons was found to be very small, which supports the existence of traditional monogamic breeding structure in nganasans.
