The dark-hair genes are epistatic to the red hair locus . 黑發(fā)基因?qū)τ诩t發(fā)基因位點來說是上位遺傳的。
To deal with dependent problems with epistatic interactions , experimental study of cga for nk landscape problem is given 對于不可作獨立子問題分解的問題,則以基因連鎖一般模型? nk模型進行了實例研究。
The methods proposed by wang et al ( 1999 ) could analyze additive effects , additive by additive epistatic effects and their interaction with environments , but could not estimate dominance effects and epistatic effects related to dominance Wang等( 1999 )的方法能夠分析加性效應(yīng)、加加上位性效應(yīng)及共與環(huán)境的互作效應(yīng),但無法估計顯性以及與顯性有關(guān)的上位性效應(yīng)。
The results oft - test indicated that few genetic main effects of qtls found were significant , among which additive by additive epistatic effects and additive effects were most significant for qtls controlling heading date , additive effects were most significant for qtls controlling kilo - grain weight T測驗的結(jié)果表明,鑒別出的qtl中,遺傳主效應(yīng)達到顯著的不多,其中抽穗期的qtl以加加上位性效應(yīng)和加性效應(yīng)最為顯著,千粒重以加性效應(yīng)最為顯著。
Genetic models were constructed for qtl mapping by two - dimensional searching . corresponding analysis methods were also proposed , which could estimate additive effects , dominance effects , epistatic effects of additive by additive , additive by dominance , dominance by additive , dominance by dominance , and could predict their interaction effects with environments 構(gòu)建了可以估汁加性效應(yīng)、顯性效應(yīng)、加加、加顯、顯加、顯顯上位性效應(yīng)以及預(yù)測這些效應(yīng)與環(huán)境互作效應(yīng)的qtl定位兩維搜索遺傳模型,提出了相應(yīng)的分析方法。
