GENETIC ANALYSIS OF MICROSATELLITE LOCI IN TWO MINIATURE PIG BREEDS

Aide Wang

Abstract

The polymorphism of 35 microsatellites in the two miniature pig breeds in China(Guizhou miniature pig, Guangxi Bama miniature pig)was analysed. Mean heterozygosity, polymorphism information content for each breeds, and genetic distances between two breeds were estimated. The results suggest that both polymorphism information content and mean heterozygosity in the two breeds are low. Mean effective number of alleles is similar to observed number of alleles, suggesting that both breeds have stable heredity. There is a close genetic relationship between Guizhou miniature pig and Guangxi Bama miniature pig, and both Guizhou and Guangxi Bama miniature pig have been two different closed colony animals.
