结果表明，这些指标的上位效应均不显著，均符合加性—显性遗传模型。
The result showed that the epistatic effect in all of those traits were not significant.
上位效应平方和占总产仔数和活产仔数总遗传变异平方和的比例分别为6 3%和6 5 % ，可见上位效应对窝产仔数群体间遗传差异作用不大。
Epistatic component accounted for 6 3% for the total number born, and 6 5% for the number born alive, which showed that epistatic effect was not important in the genetic variation between populations.
其它35.3%的QTL没有本身的加性效应，却参与了上位性互作，这些位点可能通过诱发和修饰其它位点而起作用。
The other 35.3 per cent QTLs did not have any significant additive effects of their own but were also involved in epistatic interactions.
因此传统方法对QTL加性效应的估算会由于上位性的影响而有偏。
This might mean that the usual estimates of the QTL additive effects could be confounded by epistatic interactions and result in biased estimation.
一次支梗数表现有明显的上位性效应。
小麦幼苗抗旱相关性状以及平均隶属函数值受加性效应QTL和上位性效应QTL共同作用。
The interaction effects influenced the direct effects. 3. The drought tolerance related traits were determined not only by both additive QTLs and epistatic QTLs.

The interaction effects influenced the direct effects. 3. The drought tolerance related traits were determined not only by both additive QTLs and epistatic QTLs.
