有效种群规模是选择程序定义中的一个关键参数,因为该参数的大小决定了种群中的近亲繁殖率和遗传漂移量。由于选择对有效规模具有累积效应,因此对选定群体的有效规模的预测变得复杂。本文总结了预测选择群体有效规模的两种基本方法,并阐明了它们之间的相互关系。还回顾了与动物育种相关的实际情况的一些扩展,例如非随机交配、指数选择和标记辅助选择。
The effective population size is a key parameter in the definition of selection programs, because the magnitude of this parameter determines both the rate of inbreeding and the amount of genetic drift in the population. Prediction of the effective size of selected populations is complicated by the fact that selection has a cumulative effect on the effective size. In the present article, two basic approaches to predict the effective size of populations under selection were summarized, and the interrelation among them was clarified. Several extensions to practical situations relevant to animal breeding, such as non-random mating, index selection and marker-assisted selection, were also reviewed.
