摘要
对我国13个家驴品种367条序列(其中引用文献资料241条)的mtDNA D-loop区399bp进行分析,共检测到96种单倍型57个多态位点,其单倍型多样度为0.767~0.967,核苷酸多样度为0.014~0.032,表明我国家驴的遗传多态性丰富。与3个努比亚野驴、3个索马里野驴和6个亚洲野驴的序列构建NJ系统发育树,证明我国家驴的母系起源为非洲野驴中的索马里驴和努比亚驴,亚洲野驴不是中国家驴的母系祖先。
Analysis of the 367 mtDNA D-loop sequences (of which 241 sequences were collected from literature) of 399 bp in 13 Chinese domestic donkey breeds revealed 96 different haplotypes with 57 polymorphic sites. The haplotype diversity and the nucleotide diversity were 0.767-0.967 and 0.014-0.032, respectively, indicating abundant genetic diversity in Chinese domestic donkeys. The Neighbor-joining tree of Chinese domestic donkey sequences was constructed with 3 Nubian wild ass sequences, 3 Somali wild ass sequences and 6 Asian wild ass sequences. Our results suggest that the maternal ancestor of Chinese domestic donkeys is highly likely to be Somali and Nubian of African wild ass instead of Asian wild ass.
