| 摘 要： | 采用聚丙烯酰胺凝胶电泳法和火焰光度法对家牦牛和３个含野血牦牛群体ＴＦ，ＨＢ，Ｈｐ，ＫＥ，ＡＭＹ１和ＲＢＣＬＤＨ１６个基因座多态性的研究表明：家牦牛与３个含野血牦牛群体具有同样的多态性特征，但群体的遗传变异随野牦牛血比例的增多而减少。含野血牦牛群体之间的亲缘关系大于家牦牛，再大于野牦牛，但总群体所发生的基因分化程度很小（２７４８％）。

| Abstract: | The population of a domestic yak and three populations of the yak with wild yak blood were used to investigate the polymorphism of six loci including TF,HB,Hp,KE,AMY1,RBC LDH1 by means of polyacrylamide gel electrophoresis and flame photometer.The results showed that the polymorphism characters of the domestic yak population were identical with those of three yak populations with wild yak blood.The genetic variability of populations decreased with increasing wild yak blood.The relationship among the yak populations with wild yak blood was the most close,more close among them and domestic yak population,and more distant among them and wild yak population,but the coefficient of gene differentiation of total yak population was very small(0.02748). |
