Abstract: Objective To establish a simple and effective technique for detecting haplotype and heteroplasmy of mtDNA,and investigate their frequencies in Chinese Han population.Methods The fragments from 29~290 nt of mtDNA HVⅡ from peripheral leukocytes of 200 unrelated Wuhan Han individuals were analyzed by using PCR-DGGE technique.Results Seventeen haplotypes were found in the range of 29~290 nt,and the haplotype diversity(HD) was 0.884 4.The heterogeneity was observed from 4 individuals,and its frequency was 2%.Conclusion PCR-DGGE is a simple,sensitive and effective technique in analyzing polymorphism and heteroplasmy of mtDNA,and can be used in forensic practice.

Key words: mtDNA, denaturing gradient gel electrophoresis, Haplotype, Heteroplasmy
