Molecular genetic diversity of Fujian domestic duck breeds

By using 28 micro-satellite markers with better polymorphism, this paper studied the genetic diversity of four Fujian provincial domestic duck breeds Jinding, Putian black, Liancheng white, and Shanma. According to the alleles frequencies, the polymorphic information content, average heterozygosity,...

description By using 28 micro-satellite markers with better polymorphism, this paper studied the genetic diversity of four Fujian provincial domestic duck breeds Jinding, Putian black, Liancheng white, and Shanma. According to the alleles frequencies, the polymorphic information content, average heterozygosity, anaqular genetic distance (DA) and Nei' s standard genetic distance (DS) for each breed were calculated. Based on DA and DS, four dendrograms were obtained by neighbor-joining (NJ) and UPGMA methods. The results showed that the average heterozygosity of the four duck breeds was 0. 5353, indicating that the protection of the genetic diversity of these breeds should be strengthened. The orders of the two types of genetic distances among the breeds were accordant, and the dendrograms were the same, reflecting that much more micro-satellite loci should be adopted to obtain more universal conclusions when the genetic diversity was analyzed. The phylogenetic relationships among the four duck breeds were in accordance wi
