Abstract
Serum samples from 170 unrelated individuals from the Suceava District of Roumania and from 199 unrelated individuals from Bucharest, Roumania were tested for Gm(1, 2, 3, 5, 6, 13, 14, 17, 21) and Km(1)[Inv(1)]. Selected samples were also tested for Gm(15) and Gm(16). The frequencies of the three common Caucasoid haplotypes, Gm 3, 5, 13, 14, Gm 1, 17, 21, and Gm 1, 2, 17, 21 in these two populations were found to be similar to those in neighboring Slavic states and Hungary. Racial admixture was evidenced by the presence of the Gm 1, 13, 15, 16, 17 and Gm 1, 3, 5, 13, 14 haplotypes, which are primarily Mongoloid, and the Gm 1, 5, 13, 14, 17 haplotype which is primarily Negroid. Comparisons of these data with those from earlier studies of populations from Central Europe indicate that the frequency of the Gm 3, 5, 13, 14 haplotype within this region is high and essentially uniform. Published data for several blood group systems also indicate essentially uniform distributions of frequencies in this region. It is suggested that this region may be the center of a clin that radiates from it.
