Open publisher page 1 citations

Abstract

7 native sheep populations in Western China were analyzed with the 30 microsatellite markers selected.The samples also included one of the foreign breeds In this article,the genetic relationship and variation between and within breeds are described.The results showed that only part of The segments in MB067 and BL6 loci with PCR was acquired.The other loci showed high diversity and heterozygosity in the populations.The Ds genetic distance with DISPAN soft pack was accounted,and the dendrograms were draw ed with NJ and UPGMA method.The dendrogram relationship between different sheep breeds was generally in accordance with their origins,breeding history and localities,but the different viewpoints should be discussed more in the future.
