用第11届国际组织相容性会议人类学课题的第2套血清180份,以标准方法检测了58例贵州苗族人群的HLA-A、-B、-C位点抗原并计算了其基因频率。苗族人群最常见的Ⅰ类抗原及其基因频率是:HLA-A2 0.310,A11 0.431、BW46 0.160,BW60 0.125,BW75 0.112,CW7 0.174,CW9 0.176。用本研究所获的有代表性的基因频率和同批抗血清所获的其他民族以及贵州汉族的相应频率比较,贵州苗族和贵州汉族、布依族以及南方汉族接近,和北方汉族间的差异具显著性。树系图也证实了这种聚集。本研究支持中华民族可分为南北两大人群的观点。
180 cases of the second set of serum in the anthropological issue of the 11th International Organizational Compatibility Meeting were used to detect the HLA-A, B and -C site antigens of 58 Miao people in Guizhou province by standard methods and their gene frequencies were calculated . The most common class I antigens and their gene frequencies in Hmong are: HLA-A2 0.310, A11 0.431, BW46 0.160, BW60 0.125, BW75 0.112, CW7 0.174, CW9 0.176. Compared with the corresponding frequencies of other ethnic groups in the same batch of antisera and that of Guizhou Han nationality, the differences between Guizhou Miao nationality and Guizhou Han nationality, Buyi nationality and southern Han nationality and between northern Han nationality Significance. Tree mapping also confirmed this aggregation. This study supports the view that the Chinese nation can be divided into two groups: the North and the South.
