| In this study, a referencing flock was utilized to investigate genetic polymorphism from Mutton-wool Strain of Gansu Alpine Fine Wool Sheep by microsatellite marker for the first time.There were calculated that allele frequencies,genotype frequencies,effective number of alleles,heterozygosis and polymorphisms information content for fifteen microsatellite loci (BM3413,BMS 1724,BP33,MAF70,MCM38,OarHH35,BM3033,BMS64 8,OB2,MCMA26,BM1577,BM3501,BM6438,BM6506,BMS2145),at the same time,the cor- relation was analyzed between microsatellite marker and productive trait.Fifteen microsatellite loci analyzed were highly genetic polymorphism(PIC>0.5) except BM3413 intermediately genetic polymorphism(0.25 |
