【摘要】 本研究采用淀粉凝胶电泳法首次对我国１２个水牛类群共１０５８头水平血清白蛋白多态性进行了＊检测。结果表明我国水平血清白蛋白多态性主要受＊Ａ１ｂＡ和ＡｌｂＸ两个等位基因控制，其基因频率分别为０．２２８和０．７７０，表现为ＡＡ、ＡＸ和ＸＸ３种基因型。各＊类群间基因频率差异不显著（Ｐ＞０．０５），遗传距离很＊近，具有同源关系。同时在中国沼泽型水牛中发现，原＊认为仅在在于江河型水平的ＡＩｂＢ基因，可能说明两型水牛在起源上有一定联系。更多还原

【Abstract】 The serum albumin polymorphism of 1058 animals from twelve Swamp buffalo types in China were analyzed by starch gel electrophoresis. Three phenotypes controlled by two co-dominant alleles ( AlbA and Albx ) were identified. The fre- quencies of AlbA and Albx are 0. 228 and 0.770, respectively. There are no significant differenoes in gene frequencies among all the buffalo types (P> 0. 05 ) , which indicates that their genetic variances are slight and their origins are the same.更多还原
