摘　　要：采用垂直板聚丙烯酰胺凝胶电泳技术,对云南、贵州和四川三省6个品种,每个品种均采样60个个体,共360个个体的CA、Amy-Ⅰ和Cp3个基因座位的蛋白质多态性进行了检测。结果表明,在6个品种中CA、Amy-Ⅰ和Cp3个蛋白位点均表现出多态性,其中CA和Cp各有3种表型,分别受2各共显性等位基因控制;Amy-Ⅰ具有6种表型,受3各共显性等位基因的控制。In the present study, analysis of 3 gene loci of six native pigs in Southwest China in all 360 individuals were carried out by means of horizontal starch gel electrophoresis,including Carbonic anbydrase (CA), Amyloglucosidase(Amy-Ⅰ), Ceruloplasmin (Cp).The result showed that polymorphism was found in all loci of 6 breeds.There were three and Cp which were controlled by two autosomal codominant alleles respectively;and there was six phenotypes in Amy-Ⅰ which was controlled by three autosomal codominant alleles.
