Abstract:

All 126 mtDNA D-loop sequences 399 bp in length from 12 Chinese domestic donkey breeds were analyzed, including 26 sequences published before. The results revealed 36 different haplotypes with 37 variable sites.The haplotype diversity and the nucleotide diversity were 0.466 7-0.977 8 and 0.001 2-0.028 5, respectively, indicating high level of genetic diversity in Chinese domestic donkeys. A Neighbor-joining tree constructed using 36 haplotypes of Chinese domestic donkeys, 3 sequences from Nubian wild ass, 3 sequences from Somali wild ass and 6 sequences belonging to Asian wild ass firstly showed that the maternal origin of Chinese domestic donkeys was from Somali and Nubian wild ass in Africa but not from Asian wild ass We also discussed transport of donkeys among different regions in China
