The polymorphism Distribution of Y-chromosome haplotypes in a miao population of Guizhou

摘要: PCR-RFLP was used to detect the frequency of Y-chromosome haplotypes consisted of thirteen singly nucleotide polymorphism allelesin Miao people. Nine Y-chromosome haplotypes (H1, H2, H5, H6, H7, H8, H9, H11, H12) were found in the samples. The frequency distribution of these haplotypes in Miao people were very similar to that in other southern pepulations in China, including Han, Tujia, and Yi people. It indicates that there is closer genetic relationship among southern Han, Tujia, and Yi populations implicating a common ancestry.
