Allele frequencies and The hardy. Weinberg equilibrium 基因频率与 Hardy-Weinberg平衡 Ⅹ1=X12 X12=2x 22 The Hardy-Weinberg principle of genetic equilibium describes the relationship between allele frequencies and genotype frequencies under the assumption of random mating. This principle applies to loci with alleles, loci with multiple alleles, and X-linked loci.Allele frequencies and The Hardy￾Weinberg equilibrium 基因频率与Hardy-Weinberg平衡 X11 = x1 2 X12 = 2x1x2 X22 = x2 2 The Hardy-Weinberg principle of genetic equilibium describes the relationship between allele frequencies and genotype frequencies under the assumption of random mating.
