Abstract
Yamada's method of estimating genetic co-variances between traits measured in different experimental units is discussed. It is shown that if the data are unbalanced, this method gives biased estimates of genetic covariances unless the traits have identical genetic and residual variances. An alternative unbiased procedure is suggested.
摘要
本文讨论了山田在不同实验单位测量的性状间遗传协方差的估计方法。结果表明，如果数据不平衡，该方法会对遗传协方差产生有偏估计，除非性状具有相同的遗传和剩余方差。本文提出了一种替代的无偏程序。
