n.[生]超顯性

The classical hypotheses-dominance hypothesis and overdominance hypothesis were reviewed and evaluated in this article. 筆者綜述了雜種優(yōu)勢遺傳基礎(chǔ)的兩個經(jīng)典假說-顯性假說和超顯性假說的基本觀點、不足之處。

In Population H21 Mol7, nine QTL were detected for resistance to ACB, which were localized on chromosome 1,4,5,8 and 10. These QTL showed predominantly overdominance, subsequently dominance or partial dominance gene action. 對H21×Mo17群體，共檢測到9個抗性QTL，分別位于染色體1、4、5、8、10上，表現(xiàn)的基因效應(yīng)以超顯性為主，此外還有顯性效應(yīng)和部分顯性。

The inheritance of plant was characterized as overdominance; 株高的遺傳為超顯性遺傳。
