| Abstract: | All 89 mtDNA Cytb gene sequences from five Chinese domestic donkey breeds were analyzed. The results revealed 26 different haplotypes with 30 variable sites. The haplotype diversity and the nucleotide diversity were 0. 722～0. 829 and 0. 0042～0. 0050, respectively, indicating high level of genetic diversity in Chinese domestic donkeys. The Neighbor-joining tree showed that Chinese domestic donkeys had two maternal origins including Somali and Nubian lineages. |
