Objective To investigate the polymorphisms of 23 Y-STR loci in a Han population in Jiangsu province. Methods Blood samples were collected from 4821 unrelated healthy Han males in Jiangsu province. DNA templates were amplified by PowerPlex Y23 kit,and the amplification products were detected by 3500xL genetic analyzer. Then,we calculated the allele frequencies and gene diversities respectively,as well as the haplotype frequencies and haplotype diversities. Results The gene diversity of these 23 Y-STR loci ranged 0.4099-0.9696. A total of 4781 haplotypes were detected,of which 4743 were found once. The haplotype diversity was 0.99999812. Conclusion The 23 Y-STR loci used in this study are highly polymorphic in Han individuals in Jiangsu province and therefore suitable for population genetic study and forensic individual identification.
