本文提出了研究相关遗传变异的一个新的遗传参数——相关遗传力,它是单个性状遗传力在两个相关性状上的推广,可定义为两性状的遗传协方差对两性状表现型标准差乘积之比。本文证明表型相关系数等于相关遗传力和相关环境力之和,并着重讨论了相关遗传力在间接选择和相关遗传变异分析等方面的应用,指出在这些方面,用相关遗传力代替遗传相关系数,可以得到较简单且较满意的结果。
In this paper, we propose a new genetic parameter-related heritability, which is related to genetic variation. It is a generalization of the heritability of a single trait in two related traits. It can be defined as the standard deviation of the two trait covariates The product of the ratio. This paper proves that the phenotypic correlation coefficient is equal to the sum of related heritability and related environmental forces, and focuses on the application of heritability in indirect selection and related genetic variation analysis. It is pointed out that in these aspects, the relative heritability is used to replace the genetic correlation coefficient , You can get more simple and more satisfactory results.
