运用荧光标记微卫星分析6个肉山羊品种遗传多样性
Genetic diversity of six meat goat breeds revealed by fluorescent microsatellite markers
摘要
Abstract
Genetic variation of 5 Chinese indigenous meat goat breeds and one introduced breed were exam ined using 10 microsatellite DNA markers. Ten of all the microsatellite loci were highly polymorphic and effective markers for analysis of genetic diversity and relationship among goat populations. The result showed that 6 meat goat breeds have high genetic diversity. The genetic differentiation was low between meat goat breeds which dis played only 8.2% of the total genetic variance among the different breeds. Neighbour-joining (NJ) dendrogram clustered Chinese indigenous meat goat breeds and Boer goat into different groups. Furthermore, Chinese indige nous meat goat breeds were grouped into several different phylogenetic clusters which corresponded to the geo graphic regions. This grouping pattern was further supported by both UPGMA dendrogram and scatter plots of estimates from principal component analyses. These results may provide a scientific basis for the characteristiza tion, conservation and utilization of Chinese meat goats.关键词
