[Genetic analysis of Y chromosome and mitochondrial DNA poly-morphism of Mulam ethnic group in Guangxi, China]

Abstract

In order to study the molecular genetic structure of Mulam ethnic group in Guangxi, China, Y chromosome and mitochondrial DNA(mtDNA)polymorphisms were genotyped. High frequencies of the Y chromosome haplogroups O1a1-P203 and O2a1*-M95 were found in Mulam, exhibiting a pattern similar to the neighboring indigenous populations, especially the Daic populations. MtDNA lineages F1a, M*, B4a, B5a, M7b, and N9a were found in Mulam, which always present at high frequencies among the populations of East Asia. Mulam exhibits genetic characteristics of southern Chinese in both paternal and maternal lineages. Multiplex detection of the 17 Y-STR loci and mtDNA HVS-I revealed the distribu-tion of highly genetic diversity in Mulam, which would have potential application in population genetics and forensic practice.
