Genetic polymorphisms of 32 Y-STR loci in Meizhou Hakka population

Abstract

Using AGCU Y24 Plus PCR Amplification Kit, 32 Y short tandem repeat (STR) loci were analyzed in 355 unrelated male participants of Meizhou city in Guangdong Province of China. By analyzing 341 different haplotypes, it was found that haplotype diversity (HD) and discrimination capacity (DC) were 0.9995 and 0.9605, respectively. Population relationships were analyzed by comparing Hakka population with ten other populations. The results indicate that Meizhou Hakka population was closely related to Guangdong Han population. These data were valuable for both forensic applications and population genetics.
