摘  要:
从 3 0个随机引物中筛选出 5条 ,对哈萨克羊、蒙古羊、兰州大尾羊、同羊、大尾寒羊、小尾寒羊共 6个绵羊品种的基因组进行扩增分析 ,然后用 6种聚类方法 (欧氏距离、夹角余弦、皮尔逊相关、车贝雪夫距离、街区距离、明考夫斯基 )进行聚类。结果表明 ,分布在我国西北部的绵羊品种以及大尾寒羊在大多数情况下总是先聚在一起 ,相对分布于中原地带的同羊、小尾寒羊总是和西北部的品种间距离较远。同羊和小尾寒羊之间距离也很远 ,较接近品种志中的记载。6种聚类方法均可

摘  要:
RAPD primers selected from thirty primers were used to estimate the genetic distance of 6 Chinese indigenous sheep breeds. The results showed that the Kazakh sheep, Mongolia sheep, Lanzhou Big Tail sheep, and Big Tail Han sheep often be clustered together earlier, that the Tong sheep and Small Tail Han sheep had a farther distance each other as well as compare with former four sheep breeds. 6 cluster methods all could be used to estimate the genetic distance of 6 sheep breeds well.
