查询词典 epistasis

For comparison, two QTL mapping softwares, QTL Network 2.0 and Windows QTL Cartographer 2.5, were used to verify the QTL mapping result without considering the cytoplasmic effect and cytonuclear epistasis.

为了便于比较，本文同时采用QTL Network 2.0和Windows QTL Cartographer 2.5软件在不考虑细胞质背景的情况下进行有关QTL的重演性验证。

Conversely, there is also the same amount of evidence that mutations show no epistasis or antagonistic interactions (each additional mutation has a disproportionally small effect).

相反，也有相同数量的证据表明突变没有上位效应，或者是突变没有拮抗的互作（每增加一个突变，只产生小的、不成比例的影响）。

This relationship between number of mutations and fitness is known as synergistic epistasis.

这种突变数量与适合度之间的关系被称为增效性上位。

A total of 22 main effect QTLs and 66 pairs of epistasis were associated with AC and PC.

利用QTLMapper共检测到22个主效QTL和66对显著互作位点与直链淀粉含量和粗蛋白含量有关。

However, We think that heterosis is caused by the complex effects of dominance, over-dominance and epistasis.

作者认为，杂种优势的产生是显性效应，超显性效应和上位性效应共同作用的结果，不可能只是一种基因效应在起作用。

All QTLs detected in this study were affected by epistasis of additivexadditive and interactions of QTLsxE.

本研究所定位到的QTLs中都存在加×加上位性效应牙QTL与环境的互作效应。

"Epistasis:an interaction between nonallelic gene s, especially an interaction in which one gene suppresses the expression of another."

异位显性：非等位基因的相互作用，尤其是一个基因对另一个基因所表现的显性现象。

In most groups,epistasis effect is found to be existing and the additive effect,and dominance effect are also widely functioning.

我国玉米单产和商品品质与发达国家相比还存在不小的差距，今后一段时期内，继续挖掘玉米的增产潜力和改良玉米的商品品质，仍然是非常重要的主攻方向之一。

However, because of the limitation of technology and the lack of flexible statistical method, epistasis, especially the cytonuclear epistasis was neglected too often in complex trait studies.

然而，由于技术发展的限制和相关统计分析方法的缺乏，上位性，特别是核质互作上位性在复杂性状遗传中的重要性常常被研究人员忽视。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
