猪主要经济性状候选基因的研究进展

随着人类基因组计划的完成和动物基因组计划的进行,许多控制动物经济性状的主基因逐渐被发现,并显示出巨大的应用前景。本文概述了影响猪繁殖、肉质、生长发育等主要经济性状的主基因的基因大小、基因定位和基因效应等,对主基因的研究在动物遗传育种科学发展中的意义也作了一些阐述。 Abstract:With the accomplishment of human genome project and the development of animal genome project,many major genes affecting animal economic traits were gradually detected,and they show great application prospect.Major genes affecting reproductive traits,meat quality traits,growing and developing traits of pig are summarized from their size,location and effect.In addition,the meaning of major gene in the improvement of animal breeding and genetics is also discussed.
