[A survey on distribution of red cell blood group systems in naxi and primi ethnic groups].
A survey of distribution of red cell blood group systems, including ABO, MNSs, Rh and P, was carried out on the Naxi and Primi ethnic groups in Yunnan province. The results based on 104 cases in each of the two ethnic groups showed that both Naxi and Primi possessed a high gene frequency r of 0.6082 and 0.6882, respectively, with gene frequency p = q. The gene frequency m of Naxi (0.8509) was found to be very high among the populations studied in China until now, only next to that of Lizu (0.8709). The most common phenotype of Rh system was CcDE- in both Naxi and Primi, with a quite high cDE frequency. No case of Rh negative was observed in the two ethnic groups. The P1 in Naxi approximated to that in Primi. The red cell blood group systems and their genetic distances suggested that the Naxi and Primi was genetically close to ethnic groups of North China, but different from those of South China. This fact suggests that these two ethnics groups originated from the North China.
