The effective size of monogamous populations with heritable variation in fitness is formulated, and the expression obtained is compared with a published equation. It is shown that the published equation for dioecious populations is inappropriate for most animal and human populations, because the derivation is implicitly based on the assumption that zygotes are produced by random union of gametes, each from conceptual male and female gametic pools. A convenient equation for practical use is proposed, and the application is illustrated with the estimation of the effective size of a rural human community in Japan.
推导了具有可遗传适合度变异的一夫一妻制种群的有效大小，并将所得表达式与已发表的方程进行比较。结果表明，已发表的关于雌雄异株种群的方程不适用于大多数动物和人类种群，因为该推导隐含地基于这样的假设：合子是由配子的随机结合产生的，每个配子分别来自概念上的雄配子库和雌配子库。提出了一个便于实际应用的方程，并通过对日本一个农村人类社区有效大小的估计来说明其应用。
