遗传相关(genetic correlation)
遗传相关(genetic correlation)两个性状育种值之间的相关，有时也指基因型值之间的相关，遗传分析中往往要区分性状间相关的遗传原因和环境原因。相关的遗传原因主要是基因的多效性，如果同一环境差异对两个性状有同向或异向影响，则会产生环境相关。根据协方差之间的关系以及相关系数与协方差和相应方差的有关公式，可得到表型相关(rP)、遗传相关(rA)和环境相关(rE)之间的关系式：rPxy=hxhyrAxy+exeyrExy式中hx和hy是二性状遗传力的平方根，ex和ey是环境率(e2=1-h2)的平方根。上式表明，如果两个性状的遗传力都高，则表型相关主要由二者间的遗传相关所决定；反之，若二性状的遗传力都低，则环境相关是表型相关的主导因素。表型相关与遗传相关不一定总是吻合的，二者间有时可能数值相差甚大，甚至于符号也可能相反。遗传相关的估算方法很多，常用的有协方差分析法、同胞分析法、交叉协方差法以及相关响应法等。遗传相关(genetic correlation)两个性状育种值之间的相关，有时也指基因型值之间的相关，遗传分析中往往要区分性状间相关的遗传原因和环境原因。相关的遗传原因主要是基因的多效性，如果同一环境差异对两个性状有同向或异向影响，则会产生环境相关。根据协方差之间的关系以及相关系数与协方差和相应方差的有关公式，可得到表型相关(rP)、遗传相关(rA)和环境相关(rE)之间的关系式：rPxy=hxhyrAxy+exeyrExy式中hx和hy是二性状遗传力的平方根，ex和ey是环境率(e2=1-h2)的平方根。上式表明，如果两个性状的遗传力都高，则表型相关主要由二者间的遗传相关所决定；反之，若二性状的遗传力都低，则环境相关是表型相关的主导因素。表型相关与遗传相关不一定总是吻合的，二者间有时可能数值相差甚大，甚至于符号也可能相反。遗传相关的估算方法很多，常用的有协方差分析法、同胞分析法、交叉协方差法以及相关响应法等。
