Title: The Comparison of Structural Loci and Microsatellite Marker on Genetic Differentiation in Sheep(goat) Populations
Abstract: The genetic examination on 14 structural loci and 7 microsatellite marker was carried out among the random samples in Hu sheep(Hu),Tong sheep(Tong)and Yantse Rive Delta White goat(Csb);Mean heterozygosity(H),mean polymorphism information contents(PIC)and mean effective numbers of alleles(Ne)calculated using above two type of genetic marker data were compared;The standard genetic distances among 3 populations based on two type of gene frequency were calculated and compared.The results show that:Mean heterozygosity(H),mean polymorphism information contents(PIC)and mean effective numbers of alleles(Ne)based on 7 microsatellite markers were greater than that on structural loci.There were same tendency among 3 populations;The standard genetic distances based on structural loci among 3 populations were 0026802487,the standard genetic distances based on microsatellite markers were 0232112313,The distance between sheep and goat population was much larger than between sheep populations.The study indicates structural loci and microsatellite marker reflect the genetic variation of the 3 populations consistently:TongHuCsb.Differentiation on evolution between related species could be expressed more effectively by microsatellite marker than structure marker,FCB11,MAF33,AE101,FCB128,and FCB304 could be used as representative loci for research on genetic differentiation between sheep and goat.
