Abstract

Under the same conditions which yield 1 + 4Nemu as the effective number of neutral alleles maintained by fresh mutation at a rate mu at an autosomal locus in a population of size Ne, the corresponding number at an X-linked locus is 1 + 3Nemu. The resultant bimodal frequency distribution for the effective number of alleles does not seem to have been used as the basis for analysis of data on actual numbers of alleles in natural populations.

摘要

在相同条件下，对于一个大小为(Ne)的种群中常染色体位点上以突变率(\mu)通过新突变维持的有效中性等位基因数为(1 + 4N_{e}\mu)，而在(X)连锁位点上相应的数字是(1 + 3N_{e}\mu)。等位基因有效数目的双峰频率分布似乎尚未被用作分析自然种群中等位基因实际数量数据的基础。
