| 摘 要： | 采用垂直板聚丙烯酰胺凝胶电泳技术对 68 只小尾寒羊血清酯酶多态性进行了研究。结果表明:1)被检小尾寒羊血清酯酶多态性受 Es+和 Es-一对等位基因控制,频率分别为 0.438 7 和 0.561 3,呈现出两种表型 Es(+)型和 Es(-);2)小尾寒羊血清酯酶基因座基因杂合度为 0.492 5,群体间基因分化系数很小(0.40 %)。

| Abstract: | individuals of Small-tail Han sheep were used to study the polymorphism of serum esterase by means of polyacrylamide gel electrophoresis. The results were as follows: 1)Two phenotypes distribution, namely Es( ) and Es(-), were founded in the serum esterase locus ,which was controlled by two alleles Es and Es -in the Small-tail Han sheep examined. The Es- was a preponderant allele (0.561 3) and the Es was 0.438 7. 2). The gene heterozygosity was 0.4925 on the locus of serum esterase. The gene differentiation coefficient among populations was very small (0.40 %). |
