摘要
以随机抽样（ｎ＝１５０）调查了江孜固有山羊群体的外部形态特征，用淀粉凝胶电泳法检测了该群体（ｎ＝６０）八个血液蛋白位点的多态性。结果表明，江孜山羊群体在Ｔｆ，Ａｌｐ、α２、ＰＡ－３ 四个位点上表现出多态，而Ｈｂ，Ａｍｙ，Ｅｓ－Ｄ，Ａｌｂ位点为单态。位点平均杂合度较低，其相对的单一性从遗传上证实了该群体的原始特征。群体的遗传结构体现了种质特性与生存地域及环境适应性的统一。
The outlook characteristics of Jiangzi goat population (n = 250) were studied at random, and & blood protein loci of this population (n=60) were examined with starch gel electrophresis. The result .showed that Jiangzi goat population is polymorphic at 4 loci of Tf, Alp, a2, PA-3, but monomorphic at loci of Hb, amy, Es-D, and Alb. The lower average heterozygosity and its relative monosomy genetically demonstrated the population's primitive characteristics. While the genetic structure demonstrated the unity among the species traits, living region and circumstance adaptation.
