Abstract

An analysis of cleavage patterns of mtDNA by restriction endonuclease was performed for fifteen Yunnan native cattle, two Kunming black and white cow, and one mithun (Bos frontalis). Two types of mtDNA molecule were detected in Yunnan native cattle: five individuals showed the type of yellow cattle (Bos taurus), the other ten showed that of zebu cattle (Bos indicus), suggesting their European and zebu origins. The mtDNA in Kunming black and white cow also consists of two restriction types. The mithun mtDNA showed the type of zebu cattle, indicating the close relationship between the origins of mithun and zebu cattle.

摘要

对15头云南本地黄牛、2头昆明黑白花奶牛和1头野牛（大额牛）进行了限制性内切酶对线粒体DNA（mtDNA）切割模式的分析。在云南本地黄牛中检测到两种类型的mtDNA分子：5头牛呈现黄牛（Bos taurus）类型，另外10头呈现瘤牛（Bos indicus）类型，表明它们分别起源于欧洲牛和瘤牛。昆明黑白花奶牛的mtDNA也由两种限制性类型组成。野牛的mtDNA呈现瘤牛类型，表明野牛和瘤牛在起源上关系密切。
