黔南布依族、苗族和水族人群ABO血型分布及基因频率

本文对黔南州布依族、苗族、水族人群ABO血型的表现型及基因型频率进行检测。结果显示:黔南布依族ABO血型分布为O>B>A>AB;苗族、水族为O>A>B>AB。3个民族ABO血型基因频率相接近;经吻合度检测,符合Hardy-Weinberg平衡定律。黔南与黔东南、黔西南布依族和苗族群体间以及黔南水族男女群体间ABO血型分布差异均具有显著性(P<0.05或P<0.01),结果提示ABO血型分布存在民族、地区和性别差异。

Gene Frequency Distribution of ABO Blood Groups in Bouyei, Miao and Sui Nationalities in Qiannan

The phenotype and allele distribution of ABO blood groups in Bouyei,Miao and Sui populations in Qiannan Autonomous Prefecture were investigated.Results showed that the phenotype distribution of these blood groups in the Bouyei population was O>B>A>AB,while it was O>A>B>ABspacing made consistent] in Miao and Sui populations.Allele frequency of ABO blood groups in the Bouyei population was similar to that in Miao and Sui groups,and the distribution of phenotypes in all three populations was in accordance with the Hardy-Weinberg equilibrium.Distribution of ABO blood group phenotypes between peoples in: the Qiannan region and the Qiandongnan region;the Bouyei and Miao populations in the Qianxian area;and in men and women of the Sui population in Qiannan region were significantly different(P<0.05).These results suggest that there are differences in the distribution of the phenotype of ABO blood group among populations of different nationalities,gender and in different regions.
