Genomic portrait of population of Jharkhand, India, drawn with 15 autosomal STRs and 17 Y-STRs

We analysed 15 autosomal STRs in 200 unrelated individuals (102 males and 98 females) and 17 Y-STRs in 102 unrelated males living in Jharkhand, India, to establish parameters of forensic interest. The examined autosomal STRs revealed high combined power of exclusion (CPE) and combined power of discrimination (CPD) as equal to 0.9999 and greater than 0.99999, respectively. The combined probability of match (CP_m) and combined paternity index (CPI) for all 15 autosomal STR loci were found to be 5.15 × 10⁻¹⁸ and 6.83 × 10⁵, respectively. A total of 97 unique haplotypes were obtained, of which 93 were observed only once. The haplotype diversity, discrimination capacity and matching probability for 17 Y-STR loci were 0.999, 0.951 and 1.09 × 10⁻², respectively. The highest gene diversity values at the single copy locus DYS635 and multi-copy locus DYS385 a/b were 0.785 and 0.823, respectively.
