| 摘 要： | 采用聚丙烯酰胺凝胶垂直平板电泳法对３７９头青海黄牛血清淀粉酶的多态性进行了研究。结果发现：⑴青海黄牛存在ＡＭＹ１，ＡＭＹ２和ＡＭＹ３三种同工酶，但只有ＡＭＹ１同工酶存在多态性；⑵ＡＭＹ１同工酶受ＡＭＹ１＾Ｂ和ＡＭＹ１＾Ｃ一对共显性等位基因控制，两者的基因频率分别为０．５２７７和０．４７２３；⑶柴达木黄牛ＡＭＹ１同工酶的多态性特征与青海东部黄牛相同。

| Abstract: | Qinghai yellow cattle were used to inverstigate the polymorphism of serum amylase by means of polyacrylamide gel electrophoresis in the vertical plate.The results were as follows:(1)There were three isozymes of serum amylase:AMY1,AMY2 and AMY3,but AMY1isozyme existed the polymorphism in Qinghai yellow cattle.(2)The polymorphism of AMY1 isozyme was controlled by both AMY1 B and AMY1 C iso dominant alleles.The frequencies of AMY1 B and AMY1 C alleles were0.5277 and 0.4723,resp.(3)The polymorphism characters of serum amylase in Chaidamu yellow cattle were similar with those in Qinghai east yellow cattle. |
