Allele and haplotype frequencies of 12 Y-chromosomal short tandem repeats (STRs) included in the PowerPlex(®) Y Systems (Promega) were determined in a sample of 150 unrelated healthy male individuals of Chinese Tuvans living in the Altay region of Xinjiang Uygur Autonomous Region. Allele frequencies and gene diversity for each Y-STR locus were determined. The observed haplotype diversity value was 0.9708. The present results can be used as Chinese Tuvan genetic information resources in routine population study and forensic analysis.
