[Genetic polymorphism of 4 microsatellites DNA in 3 goat populations and relationship with heterosis].
Gene frequency, polymorphism information contents, number of effective alleles, heterozygosity and genetic distances were studied in Boer goat, Taihang goat and Hebei dairy goat using four microsatellite markers (OarFCB11, OarAE101, McM218, McM38). The crossing effects on Hebei dairy goat and Taihang goat with Boer goat were tested. The results indicated that there are genetic polymorphisms at four microsatellite markers in three goat breeds. Four microsatellite markers can be used for genetic diversity evaluation in goat breeds. The genetic variability of Taihang goat is the highest, and Boer goat is the lowest in three goat breeds. Genetic distances between Boer goat and Hebei dairy goat is bigger than that between Boer goat and Taihang goat. The heterosis between Boer goat and Hebei dairy goat is higher than that between Boer goat and Taihang goat. It accords with testing results on actual heterosis.
