解释了两种不同方法得到的两性分离种群有效种群大小方程之间的不相容性。一种方法是文献中最常见的方法，它基于无法确定后代性别的假设。第二种方法包括识别父母和后代的性别。在某些情况下，如后代数服从泊松分布时，这两种方法得到了相同的有效尺寸表达式。然而，总的来说，第一种方法给出了错误的答案，这在性连锁基因中变得特别严重，因为只有男性的女儿的数量是相关的。性连锁基因的有效大小的预测说明了不同的交配系统。
Inconsistencies between equations for the effective population size of populations with separate sexes obtained by two different approaches are explained. One approach, which is the most common in the literature, is based on the assumption that the sex of the progeny cannot be identified. The second approach incorporates identification of the sexes of both parents and offspring. The approaches lead to identical expressions for effective size under some situations, such as Poisson distributions of offspring numbers. In general, however, the first approach gives incorrect answers, which become particularly severe for sex-linked genes, because then only numbers of daughters of males are relevant. Predictions of the effective size for sex-linked genes are illustrated for different systems of mating.
