Analysis of diversity and genetic relationships between four Chinese indigenous pig breeds and one Australian commercial pig breed

The genetic diversities and relationships of four Chinese indigenous pig br eeds and one Australian commercial pig breed have been evaluated using 27 m icrosatellites recommended by the International Society of Animal Genetics (ISAG) and the Food and Agriculture Organization (FAO). The allele frequenc ies, effective numbers of alleles and the polymorphic information content h ave been calculated. Nei's standard genetic distances have been used to con struct a UPGMA dendrogram, which has been evaluated by the Bootstrap test. The utility of microsatellites for evaluating genetic diversity of pigs is discussed.
