Genetic diversity is an important indicator of population health, especially for assessing population recovery of endangered species. To characterize the genetic diversity of Tibetan antelope(Pantholops hodgsonii) populations, we used muscle and placental tissues from accidentally killed Tibetan antelopes in Qinghai and Xinjiang and screened 11 Tibetan antelope Y-SNP-specific loci from 30 published polymorphic Y-SNP loci in bovids, of which AMELY3 (g.723 C > T) and SRYOY1 (g.167 G > A) 2 pairs of primers were polymorphic. Based on the AMELY3 locus, the haplotype diversity of Tibetan antelope Y chromosome was 0.048 ± 0.045 and the nucleotide polymorphism was 0.00006 ± 0.00005. According to the SRYOY1 locus, Tibetan antelope was divided into two haplotypes, of which H1 (g.167 G) was the dominant haplotype. Maximum likelihood tree suggests that Tibetan antelope might have two paternal origins. The haplotype diversity of Tibetan antelope Y chromosome was 0.439 ± 0.050 and the nucleotide polymorphism was 0.0008 ± 0.0004. The genetic differentiation index showed that the FST value between the male population of Tibetan antelope in Qinghai and Xinjiang was 0.6846 ± 0.0389, suggesting a strong population genetic differentiation. Therefore, integrated conservation across regions and research on sex chromosomes need more attention in the future conservation of Tibetan antelope.
