【Abstract】 The gene′s effect controlling quantitative traits is greatly noticed b y genetic academics for a long time, especially at the time when Human Genome Pr oject is to be finished. And thus, how to translate DNA segments to trait is o ne of important items. In this article, a general analysis model using molecular marker material is established for discussing the gene′s relative effect and t he translating from dominant gene′s DNA segments to quantitative trait. The res ult shows: by this way, the dominant gene′s effect can be estimated by the coef ficient of molecular marker regression equations fitting the orthogonal layout codominan t molecular marker materials under some hypothetical conditions, and thus, a met hod and theory basis for translating gene code DNA segments to quantitative trai t is presented,and a new method of animal molecular marker assistant selection is supplied in the same time.更多还原
