Analysis of Relationship and Origin among Some Chinese Domestic Duck Breeds
摘要
Abstract
To reveal the relationship and origin among some Chinese domestic duck breeds, twelve fluorescence labeling microsatellite markers were selected and used to analyze the genetic diversity of twelve domestic duck breeds and two wild duck breeds. The standard genetic distance (Ds) and genetic distance (DA) were calculated with FSTAT and Dispan after the dates were imported from Microsatellite-Toolkit software. Then, the two kinds of genetic distances between the twelve domestic duck breeds and the two wild duck breeds were analyzed by variance analysis. At last, UPGMA phylogenetic trees which were used to cluster analysis were structured based on these genetic distances. The results indicated that the genetic distances (DA) between the twelve domestic duck breeds and wild duck and Banzui duck (analysed by paired experiment mean t test) were very significant (P<0. 01). Fourteen breeds were clustered into three groups by the UPGMA phylogenetic trees, and Banzui duck was clustered into a separate group. It was initially indicated that these twelve domestic duck breeds originated from wild duck while the genetic distances between them and Banzui duck were relatively greater.关键词
