[Relationship between microsatellite DNA polymorphism and hind-quarter development in sheep chromosome 18].

Ten highly polymorphic microsatellite loci possibly linked to or correlated with the Callipyge gene were selected, according to the genetic map and linkage map of sheep chromosome 18. They were ILSTS54, TGLA337, HH47, TGLA122, BP33, OB2, BM3413, MCM38, MCMA26 and CSSM18. Polymorphisms of these microsatellites were detected in 61 Dorset (male) x Xinjiang fine wool sheep (female) samples and 76 Suffolk (male) x Xinjiang fine wool sheep (female) samples.
