摘要:

 
 
犬的驯养迄今约有1万多年,由于不同环境和不同目的人工选择形成了犬品种间或品种内极丰富的毛色多样性,经证实,这些犬的很多毛色类型与MC1R相关 MC1R在一些物种中有同源基因 本文阐述了犬MC1R多态性研究进展,并选择其它9个有代表性的哺乳动物物种与犬MC1R同源基因进行了比较,以此建立系统发育树。结果显示,10个物种的MC1R基因的分子进化关系与物种的经典分类学地位基本相符。

Abstract: Canines were domesticated approximately 10 000 years ago, The various environmental conditions and selective breeding resulted in aboudant diversity of coat colors in domestic canines. Many canine coat colors are affected by melanocortin 1 receptorMC1R. MC1R genes are homologous among different species. This article reviews the studies on MC1R polymorphism in the domestic canine. We also constructed a phylogenetic tree of MC1R genes by comparing the canine gene with those from nine representative mammalian species. Resulte show the gene phylogenetic tree accorded with Taxonomy of the ten mammals in the main.
