摘要： 对以正交表形式表现的共显性动物分子标记资料根据显性基因控制的数量性状遗传模型配合了动物分子标记回归方程.结果表明,在一定的条件下,对以正交表形式表现的显性基因共显性分子标记资料配合的分子标记回归方程,可以对显性基因的相对作用加以估计,并可作为育种的依据.运用此方法亦可以实现从基因到性状的翻译.

Abstract: The genes effect controlling quantitative traits is greatly noticed by genetic academics for a long time, especially at the time when Human Genome Project is to be finished.And thus, how to translate DNA segments to trait is one of important items.In this article, a generaLanalysis modeLusing molecular marker materiaLis established for discussing the genes relative effect and the translating from dominant genes DNA segments to quantitative trait.T he result shows:by this way, the dominant genes effect can be estimated by thecoefficient of molecular marker regression equations fitting the orthogonaLlayout codominant molecular markermaterials under some hypotheticaLconditions, and thus, a method and theory basis for translating gene codeDNA segments to quantitative trait is presented, and a new method of animaLmolecular marker assistant selection is supplied in the same time.

Key words: Molecular marker, MAS, Quantitative trait, Regression equation
