摘要
分子遗传学是微生物学、遗传学、化学、物理等学科相互交叉、相互渗透的学科。它是依据物理、化学的原理来解释遗传现象 ,并在分子水平上研究遗传机制及遗传物质对代谢过程的调控。实质上 ,分子遗传学所研究的是基因的本质及其功能和变化。本文综述了转基因技术、遗传标记、基因图谱的构建、基因图谱与QTL定位及动物基因组分析等在动物育种中的应用 ,并对其前景进行了展望。
Molecular genetics is inter- subject between microbiology ,genetics, chemistry, physics and so on .which can explain genetic phenomenon according to basic theory of physics and chemistry, and look for genetic mechanism and pathway of metabolise what has controlled it. In fact , content ,function and mutation of gene is main point in molecular genetic field. In this paper, It's reviewed about the application and foreground in animal breeding of technology of trans-gene, genetic marker, construction of gene mapping, QTL, Animal genomics.
