摘要： To investigate the genetic diversity of Chinese cattle, 96 male samples of 4 Chinese native cattle breeds were investigated using 5 single nucleotide polymorphisms specific to the bovine Y chromosome. Two previously described haplotypes (taurine Y2 and indicine Y3) were detected in 74 and 22 animals, respectively. The haplotype frequencies varied amongst the four native breeds. The taurine Y2 haplotype dominated in the Qinchuan, Dabieshan, and Yunba breeds. However, the indicine Y3 haplotype occurred in high frequency in the Enshi breed. Among the four native breeds, Yunba had the highest haplotype diversity (0.4330 +/- 0.0750), followed by Qinchuan (0.2899 +/- 0.1028) and Enshi (0.2222 +/- 0.1662), Dabieshan was the least differentiated (0.1079 +/- 0.0680). Compared with some foreign cattle breeds, the low level of haplotype diversity was detected in our breeds (0.2633 +/- 0.1030).
