Title: The Genetic Differentiation and Phylogenesis of Ujmuqin Sheep
Abstract: The genomes of 6 populations were screened by using microsatellites as molecular markers,including Ujmuqin sheep,small-tailed Han sheep,Tan sheep,Hu sheep,Tong and Yangtse River Delta White Goat.A total of 7 microsatellite markers were used and genetic diversity and genetic distance were also determined.The results showed that there were 224 alleles in 6 populations,all 7 locus showed polymorphism in all populations.Average heterozygosity of all populations was 0.9499,and the mean polymorphism information content(PIC) of all 6 populations was 0.8425~0.9294.A UPGMA dendrogram was constructed based on Nei′s standard genetic distance and DA genetic distance respectively.Hu and Tong were grouped at first,Ujmuqin and small-tailed Han clusted and then clusted with Tan sheep,Finally Yangtse River Delta White Goat clusted with all above.From this study,Ujmuqin is belong to Mongolia sheep group,it correspond with the historical records exactly.Ujmuqin and small-tailed Han sheep,Tan sheep,Hu sheep,Tong sheep,vest in Mongolia sheep group.
