Haplotype of 12 Y-STR loci of the PowerPlex Y-system in Sichuan Han ethnic group in west China

Haplotypes and allele frequencies for 12 Y-STR loci were determined in Sichuan Han ethnic population samples of 237 unrelated males living in west China. Only one haplotype was encountered in triple. Twelve of the haplotypes were encountered in duplicate, while 210 haplotypes were unique. The gene diversity was 0.9952. This study provides an essential precondition for identification of male DNA and tracing of paternal lineages.
