目的:了解贵州家人群ABO血型分布特征。方法:采用玻片快速凝聚法进行ABO血型鉴定,Hardy-Weinberg平衡检验采用卡方检验。结果:贵州省家人ABO血型分布为O>B>A>AB,基因频率为p=0.153 7,q=0.193 1,r=0.648 6,特征是r>q>p。男女间ABO血型分布差异无显著性(P>0.05),该民族ABO血型的表型分布符合Hardy-Weinberg定律。结论:贵州家人ABO血型分布与华南型相吻合,O型基因频率明显高于其他种类基因频率,具有典型的南方人群结构特征。
Objective: To understand the distribution characteristics of ABO blood group in Guizhou population. Methods: Rapid blood coagulation method was used to identify ABO blood group, Hardy-Weinberg equilibrium test using chi-square test. Results: The distribution of ABO blood type in Guizhou was as follows: O> B> A> AB. The gene frequency was p = 0.153 7, q = 0.193 1, r = 0.648 6, and the characteristic was r> q> p. There was no significant difference in ABO blood group distribution between men and women (P> 0.05). The phenotype distribution of ABO blood group in this nation accorded with Hardy-Weinberg law. CONCLUSION: The distribution of ABO blood type in Guizhou population is consistent with that of southern China. The frequency of O-type gene is significantly higher than that of other kinds of genes and has the typical southern population structure.
