The coefficients presented allow computing the expected resemblance between relatives x and y for an
observable trait given genetic variance components

假设基因型与环境之间不存在协方差,且不存在共同的环境效应:

结合前面的费希尔的育种值/分解


亲本与子代间的遗传协方差
αxi 意思是来自x的一个等位基因的加性效应
假设x和y非近郊产生,父母代和子代的共组系数Θop=1/4 △op=0,推导:![]()
半同胞间的遗传协方差

![]()
共组系数的计算在前面2章有说
全同胞间的遗传协方差

个体与自身的遗传协方差

也就是说随着等位基因数量增加 ,遗传方差增加,有何意义??不知道
