Codominant Molecular Markers and Dominant Gene Quantitative Traits

doi:10.3321/j.issn:1000-7091.2003.02.003

Abstract

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
