title: [The sequence polymorphism of Y-chromosome DNA and mtDNA of Dong Ethnic of Congjiang, Guizhou].
abstract: To study the patrilineal and matrilineal genetic structure and the origin of Dong Ethnic of Congjiang Guizhou. Study the distribution of Y-chromosome haplotypes which consisted of 10 SNPs of Y-DNA and mtDNA haplogroups consisted of 11 SNPs by using PCR-RFLP method. The result is three haplotypes H6,H11,H14 were detected, the frequency of H11 is 92.5%. Six haplogroups were identified by mtDNA analysis, 75% of the people can be identified. The patrilineal genetic structure of Dong of Guizhou is simple, Principle component indicated that the structure is closer to Zhuang-Dong branch of Sino-Tibetan language family. The matrilineal genetic structure of Dong of Guizhou is complicated.
