加性基因效应与分子标记回归方程的关系

控制数量性状的基因作用历来是遗传学工作者所关注的重要课题．本文对以正交表形式表现的共显性动物分子标记资料,根据加性效应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通式．结果表明：对以正交表形式表现的加性效应基因共显性分子标记资料配合的分子标记回归方程,可对加性等位基因的相对作用差加以估计,并可作为育种的依据．

Relations between Additive Gene Effect and Coefficients of Molecular Marker Regression Equation

The gene's effect controlling quantitative traits is greatly noticed by genetic academics for a long time.In this article,a general analysis model using molecular marker ma- terial is established for discussing relations between the additive gene effect and the coefficients of molecular marker regression equation.The result shows:By this way,the additive gene effect can be estimated by the coefficient of molecular marker regression equations fitting the orthogonal layout codominant molecular marker materials,and,in the same time,a new method of animal molecular marker assistant selection is supplied.
