...合可贡献6cm高度,或者7cm,8cm的高度,GG纯合可贡献8 cm的高度,它们的遗传方差称为加性遗传方差(additive genetic variance)。若G对g有显性作用,那么G g将贡献8 cm,显性作用使表型产生的方差称显性方差。

许多个案研究表明,入侵种源种群的加性遗传变异(additive genetic variance)程度越高,则越有利于成功入侵,而入侵成功前所经历的时滞是积累足够加性遗传变异的需要(Reznick,1997;Ellstrand,2000);入侵种...

The additive genetic variance of the same character, estimated from the covariance of half sibs, was 0. 9602.
从半同胞协方差估计出来的,同一性状的加性遗传方差为0.9602。
The variance component analysis revealed that the ratios of additive genetic variance to phenotypic variance of the majority of economic traits were high.
进一步的方差组分估计表明,主要经济性状的加性遗传方差较大。
Special attention should be given to the decrease of the additive variance of yield trait, and this will most possibly make genetic background narrow.
值得注意的是,产量性状的加性方差有降低的趋势,遗传基础可能变窄。
