Abstract:

The polymorphism distributions of microsatellite loci , BM2113、IDVGA2、TGLA44、IDVGA27、ETH10、ILSTS005、and IDVGA46 were detected in Qinchuan cattle by Polymerase Chain Reaction and multiplex gel electrophoresis followed by silver staining . The results indicated that genetic heterozygosity of Qinchuan cattle was high，genetic diversity Was rich．The selected microsatellite loci can be used to evaluate genetic diversity of Qinchuan cattle．
