摘要本文提出了一个用方差和协方差分析估计遗传相关的抽样方差的公式。如果两个性状的遗传力估计值都不为零，则公式成立。然而，发展假设一个恒定的数量的后代每公畜，k，和不同的k值的影响进行了简要的讨论。从遗传参数估计的实验的效率也进行了研究，并给出了各种组合的表型和遗传参数的最佳值k。
Summary. In this paper a formula is developed for estimating the sampling variance of a genetic correlation estimated from analyses of variance and covariance. The formula holds provided the heritability estimate of neither character is zero. However, the development assumes a constant number of offspring per sire, k, and the effect of varying values of k is discussed briefly. The efficiency of experiments from which genetic parameters are to be estimated has also been investigated and optimum values of k are given for various combinations of phenotypic and genetic parameters.
