【摘要】 本文对我国12个家驴品种126个个体(其中引用26个个体)的mtDNA D-loop区 399 bp进行分析,共检测到36种单倍型37个多态位点,其单倍型多样度为0．4667-0．9778, 核苷酸多样度为0．0012-0．0285,表明我国家驴的遗传多态性丰富。与努比亚野驴、索马里野驴和亚洲野驴的序列构建NJ系统发育树,首次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祖先。更多还原

【Abstract】 Analysis of the 126 mtDNA D-loop sequences (of which 26 sequences were collected from literature)of 399 bp in 12 Chinese domestic donkey breeds revealed 36 different haplotypes with 37 polymorphic sites. The haplotype diversity and the nucleotide diversity were 0.4667-0.9778 and 0.0012-0.0285, respectively, indicating abundant genetic diversity in Chinese domestic donkeys. The NJ tree of Chinese domestic donkeys with Nubian, Somali and Asian wild ass was constructed, which first proved that the maternal origin of Chinese domestic donkeys was from Somali and Nubian of African wild ass but not from Asian wild ass.更多还原
