| 摘 要： | 本文以mtDNA限制性内切酶片段长度多态技术分析云南牛的mtDNA多态性。结果表明云南黄牛有两种类型的mtDNA分子,一种是普通黄牛类型,另一种是瘤牛类型,两者的频率分别为33%和67%。没有发现过渡型和重组型。昆明黑白花奶牛的mtDNA与云南黄牛的相类似。云南黄牛可能具有两种起源,即普通黄牛起源和瘤牛起源。今天的云南黄牛群体是这两种类型的混合。大额牛的限制性类型与瘤牛相同,表明大额牛的起源与瘤牛有密切关系。

| 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 indicui), 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. |
