比较遗传学介绍

随着遗传作图的不断发展，人们开始比较不同物种的基因组，并且揭示了一种从未被发现的基因组水平上基因排列顺序的保守性。随之，发展出比较遗传学概念：研究基因的排列顺序和基因数量的学科。比较遗传学已经被应用于植物基因组的基因定位，并预示出进化研究的一个全新领域。目前,比较遗传学和狭义的比较基因组学相互渗透和融合，形成一门新的学科，它将大大加深人们对基因组的理解。 Abstract：With the advance of genetic mapping and comparin g of different genomes,an undiscovered type of conservation was revealed: the co nservation of gene content and gene orders on the genome level.

The Review of Comparative Genetics

With the advance of genetic mapping and comparing of different genomes,an undiscovered type of conservation was revealed: the conservation of gene content and gene orders on the genome level. And it lodged the concept of comparative genetics:the science that studies gene content and gene orders. Now comparative genetics has been used to facilitate the isolation of gene, and it indicates a new field of evolution. This review discuses the development of comparative genetics.In the future, comparative genetics and comparative genomics would be probably syncretize to be a new science, and it will deepen the understanding of genomes.
