Analysis of 23 Y-STR loci in Chinese Jieyang Han population

Genetic polymorphisms of 23 Y-chromosomal short tandem repeats (Y-STR) were investigated by PowerPlex® Y23 System in 328 unrelated male participants from Jieyang, Guangdong Province of China. A total of 293 haplotypes were obtained, and the haplotype diversity (HD) and discrimination capacity (DC) were 0.9991 and 0.8933, respectively. By comparing Jieyang population with nine other populations, Jieyang Han showed close genetic relationships with southern China-related Han populations. In conclusion, our study increased the Y-chromosome haplotype reference database and could provide useful information for forensic investigation and population genetics.
