线粒体DNA多态性与家畜遗传育种

摘要

On the basis of restriction fragment lengthpolymorphism(RFLP)technique and the specific property of mitochondrial DNA(MtDNA)，the paper has elaborated the application of MtDNA polymorphism on the breeding of livestock． To point out:the meaning of MtDNA polymorphism analysis on the study of livestock breeds resources．%在线粒体DNA的特点及其限制性片段长度多态性的基础上，阐明了线粒体DNA多态性在家畜育种上的应用。并指出线粒体DNA多态分析在家畜品种资源研究中的意义。
