| 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 Genetic Examination of Jiangzi Goat Population |
|
|
| Abstract: |
| The outlook characteristics of Jiangzi goat population (n=250) were
studied at random,and 8 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,α2,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 strueture
demonstrated the unity among the species traits,Iiving region and circumstance adaptation. |
