广州汉族人群DYS19、DYS389Ⅰ/Ⅱ、DYS390多态性及其单体型 Y-DNA STRs Polymorphisms and Haplotypes in Guangzhou Han Population

In order to apply a set of useful and high polymorphic YSTRs in forensic practice and genetic analysis,we performed a population genetic study from Chinese.The allele distributions of the systems DYS19、DYS389Ⅰ/Ⅱ、and DYS390 were investigated in sample of 111 unrelated males from the area of Guangzhou, China.PCR products were detected using polyacrylamide gel electrophoresis and silver staining.5、4、5、5 alleles were observed in locus DYS19、DYS389Ⅰ、DYS389Ⅱ、DYS390 respectively.Different allele frequency distributions were observed when compared to other population.Haplotype frequency date of 72 different types were obtained.
