Abstract

Highlights: This study reported Forensic parameters of 29 Y-STR loci of Qiang males in China. The overall haplotype diversity of Qiang population was measured to be 0.9992. These data can fill the gap of Y-STR Haplotype Reference Database of Qiang people. Abstract: This study reported the forensic parameters of the 29 Y-STR loci of 242 unrelated Qiang males in Beichuan Qiang Autonomous County. Qiang population is a minority with small size populations and has never been reported. The overall haplotype diversity of Qiang population was measured to be 0.9992 while a discrimination capacity was 0.9215. According to the haplotypic analysis of the 29 Y-STR loci, 223 different haplotypes were obtained, of which 207 (92.83%) were unique. A total of 242 different alleles were checked at all loci, the corresponding allele frequencies ranged from 0.0041 to 0.7603. In addition, pairwise genetic distances, multidimensional scaling plots and neighbor-joining dendrogram were performed to analyze interpopulation differentiation between Qiang population and 16 other ethnic groups. These data can fill the gap in the Y-STR Haplotype Reference Database of the Qiang population and may be of reference value for forensic and population genetic analysis.
