家畜育种中的分子遗传标记

THE MOLECULAR GENETICAL MARKERS IN BREEDING OF LIVESTOCK

在叙述RFLP技术、DNA指纹技术、RAPD 技术和AFLP技术的基础上，说明了分子遗传标记在家畜基因定位、基因图谱构建、背景基因型选择及杂交选育上的应用，并指出分子遗传标记应用于家畜育种需要解决的问题。

In the paper, on the basis of restrictive fragment length polymorphism, DNA fingerprint, random amplified polymorphism DNA and amplified fragment length fragment polymorphism, the application of the molecular genetical markers in the gene locus, the production of genetic map, the selection of background genetype and bybrid selective breeding of livestock were spoken. And pointed out that the questions about the application of molecular genetic markers in breeding of livestock. must be solved
