title: Distribution of red cell blood group systems in Yi, Tibetan and Manchu ethnic groups in China.
abstract: A survey on distribution of ten red cell blood group systems was carried out in 1985 in the Yi, Tibetan and Manchu nationalities in China. Significant differences were found in the distribution of Rh, MNSs, P and especially in the ABO system, while no significant difference was found for Diego, Duffy, Kell, Kidd and XG systems. The DI*a gene frequency was about 0.03, FY*a rather high (0.94), KEL*K extremely low (0.005) and JK*a was about 0.4. In the three nationalities under study, Yi is characterized by high frequencies of the alleles A, M and CDe and by the absence of CDE and Cde. Tibetans show a high frequency of O and a relatively high frequency of P*P1, while Manchus have the lowest frequency of M and in particular of MS.
