Genomic insight into Y-STR diversity in the population of Odisha, India

This study evaluated the haplotype diversity of 17 Y chromosomal genetic markers among 202 unrelated males who were randomly selected in the population of Odisha, India. Out of total 196 haplotypes observed in this study, 190 were unique haplotypes. Forensic relevant parameters, viz., gene diversity (GD) and discrimination capacity (DC), were calculated as 0.999999998 and 0.970 respectively, for the studied population. The highest genetic diversity was observed at the locus DYS385a/b (0.9541) and lowest at the locus DYS437 (0.3326) among all the studied Y chromosomal loci. The polymorphic information content (PIC), power of discrimination (PD), and matching probability (PM) was found to be 0.999999965, 0.999999998, and 1.6×10^-9 for the tested Y STR loci. The genetic data observed in this study would enrich the existing Y STR data of the Indian population and would also be useful for forensic application.
