遗传效应

Waddington said genetic assimilation, or the Baldwin effect, was about converting acquired traits into inherited traits.

沃丁顿说，基因同化过程，或鲍尔文效应，做的是将需求的特性转化为遗传特性的工作。

The results indicated that the white flower was dominant over yellow and the erucic acid content was additively inherited. Both traits fit with a monogenic inheritance model, respectively. There were strong evidences to support the linkage relationship between the flower colour and the erucic acid content in the C-genome of B. napus with a recombination frequency of 4.8% in the DH population.
