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).
为了研究中国牛的遗传多样性，使用 5 个针对牛 Y 染色体的特异性单核苷酸多态性，对 4 个中国本土牛品种的 96 个雄性样本进行了调查。在 74 个和 22 个动物中分别检测到了两个先前描述的单倍型（黄牛 Y2 和印度牛 Y3）。四个本土品种的单倍型频率有所不同。黄牛 Y2 单倍型在秦川牛、大别山牛和云岭牛中占主导地位。然而，印度牛 Y3 单倍型在恩施牛中高频出现。在四个本土品种中，云岭牛的单倍型多样性最高（0.4330±0.0750），其次是秦川牛（0.2899±0.1028）和恩施牛（0.2222±0.1662），大别山牛的分化程度最低（0.1079±0.0680）。与一些外国牛品种相比，我们的品种检测到的单倍型多样性水平较低（0.2633±0.1030）。
