Abstract

Abstract: According to report, four highly polymorphic microsatellite loci possibly linked to production traits and mapped to the region of GDF8 on sheep chromosome 2 were selected. they were BM81124，TEXAN2，FCB128，BMS1591. They were analyzed for polymorphism in Dorset,Suffolk and Texel meat sheep populations. Results showed that the number of alleles were 10,12,7,11 and polymorphic information content / Heterozygosity were 0.7778/0.8045,0.712/0.7520,0.7551/0.7852,0.8057/0.8289.We can see these microsatellite loci have rich polymorphism in three groups.So they can be used as the linkage analyse between the production traits and makers,and used for further location of QTL.
