Genetic analysis of 15 autosomal STRs in Yousafzai population of Pakistan

Yousafzai is a Pushto-speaking Pathan tribe inhabiting the northern province of Pakistan who claim to be descendants of the prophet Yousaf (Joseph). Forensic and genetic parameters were determined for 203 genetically unrelated individuals on 15 autosomal STRs. D2S1338 was the most discriminating locus whereas TPOX was the least. The combined matching probability (CMP) for all loci was 1.52458 × 10 −18 while combined power of discrimination (CPD) and combined power of exclusion (CPE) was 0.9999999999999999984 and 0.999998628, respectively. The Yousafzai population was in Hardy-Weinberg equilibrium after Bonferroni correction except for loci D3S1358 and D19S433. Pairwise genetic distance analysis was carried out by comparing with various populations at local and global levels. The findings of this study are valuable for population genetics and forensics analysis.
