在数量性状遗传的研究中,遗传力和遗传相关是其中最主要研究内容之一。遗传力(Heritability)是指亲代遗传传递某一性状给子代的能力。任何一种性状的表现型都是其内部的基因型和外部环境条件共同作用的结果。所以表型变量可分解为遗传变量和环境变量两部 In the study of quantitative trait inheritance, heritability and genetic correlation are one of the most important research contents. Heritability refers to the ability of parents to pass on certain traits to offspring. The phenotype of any one trait is the result of the interaction between its internal genotypes and the external environmental conditions. Therefore, phenotypic variables can be decomposed into two genetic variables and environmental variables
