Abstract: The PCR-RFLP techniques were used to study the mtDNA D loop polymorphism in Han ( 36 testees) , Daur ( 30 testees) , Oroqen ( 32 testees) and Ewenki ( 30 testees) . All testees were randomly selected and healthy. The polymorphisms on 10 sites of a 465bp- long DN A fragment in mtDNA D loop were detected and compared among ethnic groups.
Altogether 27 mito types were found by PCR-RFLP. The mean nucleic acid substitute frequency on each site was: Han 0. 0291, Daur 0. 0541, Oroqen 0. 0477 and Ewenki 0. 0563, respectively.

Key words: mtDNA, D loop, Genetic polymorphism
