dominance effect
dominant effect
Examples
- The genetic correlations of six agronomic characters in some indica - japonica crosses were analyzed using mixed - linear model method . the results indicated that there existed correlations to a certain degree among the measured traits . the phenotypic correlations of plant height with filled grain or seed setting were significant . panicle length with total grains or filled grain , total grains with filled grain or seed setting , and filled grain with seed setting were the same . for panicle length with plant height or seed setting , total grains with filled , and for filled grain with seed setting , genetic correlations were also significant . further analysis , the result showed that genetic correlations between the measured traits were mainly due to domimant effects . in addition , additive correlations were significant for grain weight with panicle length or total grains or filled grain , and for total grains with filled grain
用混合线性模型方法对籼粳亚种间杂交组合农艺性状的相关性进行了遗传研究，结果表明：被测性状之间大都存在一定程度的相关.其中，株高与实粒数、结实率，穗长与总粒数、实粒数，总粒数与实粒数和结实率，以及实粒数与结实率之间具有显著的表型相关，总粒数与实粒数，实粒数与结实率，以及穗长与株高和结实率之间具有显著的遗传相关.进一步的分析表明，性状之间的遗传相关大多归因于显性效应，而粒重与穗长、总粒数和实粒数之间，以及总粒数与实粒数之间还具有极显著的加性相关 - 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
构建了可以估汁加性效应、显性效应、加加、加显、显加、显显上位性效应以及预测这些效应与环境互作效应的qtl定位两维搜索遗传模型，提出了相应的分析方法。 - It was shown that in short - season cotton , the seven traits relating to early maturity all presented dominating additive effect while displaying dominance effects , and epistatic effects from sowing to budding , from sowing to flowering and from budding to flowering ; the early maturity traits significantly interacted with the environments
结果表明：短季棉7个早熟相关性状的遗传均以加性效应为主，同时存在着显性效应，对于播种现蕾、播种开花和现蕾开花还存在着上位性效应；短季棉各早熟性状的遗传效应与环境互作显著。 - The estimation of additive and dominance effects through qtl analysis by one - dimensional search while ignoring epistases showed similar accuracy to that by two - dimensional search by including epistases . existence of epistases could decrease the precision for the estimation of additive and dominance effects . the estimation of genetic main effects would be biased if ignoring the interaction effects of qtl x environment ( qe )
忽略上位性效应的一维搜索qtl分析对加性效应和显性效应的估计精度与包括上位性的两维搜索qtl分析对这两种效应的估计精度相差不大，上位性的存在可能会降低对这两种效应估计的精度；忽略qtl环境( qe )互作效应会导致对遗传主效应的有偏估计，而包括qe互作效应的多环境联合分析能够提高对遗传主效应的估计精度。 - Monte carlo simulations were conducted to study the new approaches of qtl mapping , the results indicated that general least squares ( gls ) method , which was widely applied in mixed linear model , could unbiasedly estimate all genetic main effects , including additive effects , dominance effects and epistatic effects of additive by additive , additive by dominance , dominance by additive , dominance by dominance . the interaction effects between genetic main effects and environments could also be predicted unbiasedly by linear unbiased prediction ( lup ) . the heterosis prediction based on qtl effects was also unbiased
对新提出的qtl分析方法进行了montecarlo模拟研究，结果表明，广泛应用于混合线性模型的广义最小二乘法( gls )能够无偏估计加性效应，显性效应以及加加、加显、显加、显显上位性效应等各项遗传主效应；运用线性无偏预测法( lup )能够无偏预测上述各项遗传主效应与环境的互作效应；基于qtl效应的杂种优势预测也是无偏的。
