山羊多胎性状候选基因的研究进展

Research Progress on Reproduction Traits of Candidate Genes in Goat

多胎性状是山羊的重要经济性状,直接关系到其产业的经济效益。目前在绵羊中已经找到了影响多胎性能的若干主效基因;在山羊上,国内外对遗传机制的研究主要集中在常规选育和分子标记方面,但是仍未找到控制山羊多胎性状的主效基因。论文就山羊多胎性状候选基因的研究现状进行综述,为其主效基因的筛选及应用提供有益参考。

Multiplets properties is an important economic characteristics of goat, which is directly relat- ed to the economic benefits of the industry. At present, the major genes of prolific trait have been found in sheep. The research about prolific trait heritage mechanism of goats has been focused on the conventional breeding and molecular markers, but the major genes of prolific trait haven＇t been found. This paper sum- marized the research status, and it could provide the beneficial reference for its selection and application.
