摘要 自《Pearl and Surface》（1909）的早期工作以来，人们进行了大量的研究来确定受精卵的受精率和孵化率在多大程度上受遗传控制。生育力必须仅被视为父母的财产，因为一旦配子结合，所研究的性状就不再是生育力（Bernier，Taylor 和 Gunns，1951）。然而，人们长期以来一直认为（Warren，1927-28；Axelsson，1932）受精蛋的孵化是由两个组成部分组成的复合性状。第一个是胚胎存活的能力，第二个是母体对卵子胚胎外部分的贡献，为胚胎发育提供了环境。胚胎活力和胚胎外母体效应都可以被认为具有一定的遗传力，它们结合起来构成了受精卵孵化的遗传力（Abplanalp 和 Kosin，1953）。这 …
Abstract SINCE the early work of Pearl and Surface (1909), a great many studies have been made to determine the extent to which fertility and hatch of fertile eggs are controlled by heredity. Fertility must be considered a property of the parents only, since the trait being studied is no longer fertility once the gametes have united (Bernier, Taylor and Gunns, 1951). However, it has long been felt (Warren, 1927–28; Axelsson, 1932) that hatch of fertile eggs is a compound trait made up of two components. The first is the ability of the embryo to survive, and the second is the contribution of the dam to the extra-embryonic portion of the egg, which provides the milieu for embryonic development. Both embryonic viability and extra-embryonic maternal effects may be considered to have certain heritabilities which combine to make up the heritability of hatch of fertile eggs (Abplanalp and Kosin, 1953).
