Allele frequencies and The hardy Weinberg equilibrium 基因频率与 Hardy-Weinberg平衡 Y Allele frequency: The proportion of one allele relative to all alleles at a locus in a population 个群体内某一定等位基因的频率叫做基因频 率,其中A1的频率为 X1=(2Nn+Nn)(2N)=X+x12/2 A2的频率 X2=1-X1=X12/2+X22Allele frequencies and The Hardy￾Weinberg equilibrium 基因频率与Hardy-Weinberg平衡 ✓ Allele frequency: The proportion of one allele relative to all alleles at a locus in a population 一个群体内某一定等位基因的频率叫做基因频 率，其中A1的频率为： x1 = (2N11+N12)/(2N) = X11+X12/2 A2的频率 x 2 = 1-x1 =X12/2 + X22
