Abstract

In 6 Chinese yak (Bos. grunniens) populations including 177 yaks, 34 blood protein loci were studied by horizontal starch gel electrophoresis, four of these loci (AKP, ALB, LDH-1, TF) were found to be polymorphic. The percentage of polymorphic loci(P) is 0.118, the mean individual heterozygosity(H) is 0.015, which means a low level of genetic diversity in the whole Chinese yak population. The coefficient of gene differentiation (Gst) is 0.0625, which indicated an almost-indistinguishable divergence among different populations at the level of blood protein electrophoresis.

摘要

在包括177头牦牛的6个中国牦牛（Bos. grunniens）群体中，通过水平淀粉凝胶电泳研究了34个血液蛋白位点，发现其中4个位点（AKP、ALB、LDH-1、TF）具有多态性。多态位点百分比（P）为0.118，平均个体杂合度（H）为0.015，这意味着中国牦牛群体的遗传多样性水平较低。基因分化系数（Gst）为0.0625，这表明在血液蛋白电泳水平上不同群体之间几乎没有明显差异。
