Abstract

Abstract: The Polymorphisms distribution of 10 microsatellite Loci were determined in 154 samples of Superfine Breed nuclear Population in Chinese Merino(xinjiang army westland reclamation model) county. Polymorphism information content(PIC), effective number of alleles(E), gene heterozygosity(H) and Rate of homozygote of alleles (Rh) for all microsatellite loci were calculated. The resusts showed the 8 of 10 microsatellite Loci were highly polymorphic, and BMS772 and BM6506 was medium polymorphic ; The mean PIC, H,E, and Rh were 0.5848、0.6333、3.0315、0.4841 respectively, this population have high genetic diversity and medium rate of homozygote of alleles ; and just OARAE57 locus obeyd HardyWeinberg balance equilibrium (P>0.05).
