| Abstract: | The over-dominant gene is a kind of important gene that controls quantitative trait.The estimation of the coefficient of over-dominant gene is very important in the utilization of heterosis fully.In this article,a general analysis model of the use of co-dominant molecular marker materials was established to discuss the relation between the coefficient of over-dominant gene and the coefficients of molecular marker regression equation.The result showed the coefficient of over-dominant gene can be estimated with the coefficient of molecular marker regression equations fitting the orthogonal layout co-dominant molecular marker materials under some hypothetical conditions,and a new forecasting method of the combining ability of animals and the heterosis utilization was supplied. |
