2) additive variation
基因加性效应
1.
Results showed that:(1)the additive variation was principal in 12 leaf morphological characters such as second leaf width and flag leaf width;the nonadditive variation was principal in distance between flag leaf and second leaf,flag leaf droopy angle as well as specific leaf weight.
试验结果表明:倒2叶叶宽、剑叶叶宽等12个性状均以基因加性效应为主,而倒1~2叶叶枕距、剑叶披垂角和剑叶比叶重等3个性状以基因的非加性效应为主。
4) non-additive gene action
非加性基因作用
5) additive action of genes
基因加性作用
6) Additive gene
累加基因
补充资料:多基因效应
多基因效应
polygene effect
控制数量性状的基因是由大量基因组成的,等位基因之间无显性隐性区分,各对基因对表现型的作用是累加的,每个基因的作用是微小的,故称为多基因效应。这类基因的活动也按照基本的遗传规律,即有分离和重组,也有连接和互换。
