摘要(Abstract):

应用中心产区典型群简单随机抽样的方法,检测控制湖羊、同羊、滩羊、小尾寒羊和洼地羊的血液酶和其他蛋白质变异的5个结构基因座位(Tf、X-p、Ary-Es、Hb-β、Ke)上的遗传变异,引用国内外学者以相同实验方法获得的其他分布于我国周边国家和地区的11个绵羊品种作为分析背景,对16个群体进行遗传距离分析及亲缘关系聚类。结果表明:中亚以东南绵羊群体可以划分为蒙古羊、藏羊和南亚-东南亚羊三大集团,湖羊、同羊、滩羊、小尾寒羊和洼地羊均属于"蒙古羊"系统。
Applying simple random sampling in typical colony methods in the central area of habitat, the genetic variations of 5 structural loci (Tf、X-p、Ary-Es、Hb-β、Ke) in blood enzyme and other protein of Hu sheep, Tong sheep, Tan sheep,small-tailed Han sheep and Wadi sheep were examined. Comparing with those of 11 other sheep populations in China and other countries examined with the same method as the analyzed background, the phylogenetic relationship of 16 populations were analysed based on the genetic distance. The study shows that sheep populations in the East and south of central asia can be classified into three genetic groups: "Mongolia sheep", "Tibetan group"and"South Asia - Southeast Asia group",and Hu sheep ,Tong sheep,Tan sheep,the small-tailed Han sheep and Wadi sheep belong to " Mongolia sheep"group.
