用法和例句

With an example in pig crossing, the dissemination of genetic gain by using gene flow method is investigated.

遗传进展的传递速度是杂交繁育体系建设中的重要问题之一。

Using deterministic methods,rates of genetic gain(△G) and inbreeding(△F) were compared between pure line selection(PLS) and combined crossbred purebred selection(CCPS),for the sire line of a three-way crossbreeding scheme.

本文比较了纯系选择与组合选择两种方法在肉鸡三系配套杂交方案中父本品系遗传进展与近交速率的变化情况,模拟试验结果表明,在遗传参数和总的测定笼位一定的情况下,包含纯种与杂种信息的组合选择获得的累积遗传进展(△G)总是高于纯系选择,近交速率(△F)也高于纯系选择方法。

Effects of different allocation of selection proportion between the two selection stages on genetic gain of annual egg production were studied.

在总留种率 30 %的情况下 ,比较了第 1阶段留种率从 30 %到 10 0 %变化时对后代遗传进展的影响。

Using deterministic methods, rates of genetic gain(△G)and inbreeding(△F )of 18 breeding scheme were compared between pure line selection(PLS)and combined crossbred purebred selection(CCPS) by Monte Carlo, for the sire line of a three-way crossbreeding system, with the same genetic parameters and population size.

本试验以肉鸡三元配套系中的父本品系为研究对象,在遗传参数和总的测定笼位一定的情况下,采用Monte Carlo方法比较了纯系选择(PLS)与组合选择(CCPS)两种方法各9种方案下肉鸡体重杂种性能遗传进展与近交速率的变化情况,同时比较了组合选择相对于纯系选择的优势。

In this study,animal model BLUP method was used to estimate genetic trend for cashmere yield and bodyweight during 1989～ 1998 at Albas goats farm,Etuoke Banner,Inner Mongolia.

本研究应用动物模型BLUP法估计了1989～1998年内蒙古鄂托克旗阿尔巴斯白绒山羊种羊场抓绒量和抓绒后体重的遗传进展。

【Method】 According to the selection theory to improve quantitative characters,generation index of selection efficiency was constructed with the ratio of the genetic progress of generations to the genetic progress on the first generation in order to measure the selection effect and potential.

【方法】根据数量性状改良的选择理论,以各世代的遗传进展与第1代遗传进展之比构建了选择效率世代指数,以度量各世代的选择效果和潜力。
