Abstract
To explore the genetic diversity and establish the allelic database of the population of Rajasthan, we assessed 571 randomly selected unrelated healthy individuals residing in the state. Blood samples of the selected individuals were collected with the compliance of ethical standards. Locus Penta E was observed to be the most polymorphic (0.908), whereas locus TPOX was observed to be the least polymorphic (0.639). The observed heterozygosity ranged from a minimum of 0.667 (TPOX) to a maximum of 0.925 (Penta E). The combined value of the power of discrimination (PD) and power of exclusion (PE) for all the studied 20 short tandem repeat (STR) loci were observed to be 1 and 0.999999997560235 respectively. The combined values of matching probability (PM) and paternity index (PI) for all the studied 20 STR loci were 7 × 10−26 and 4 × 108 respectively. The obtained genetic data are useful for forensic DNA applications and expected to enrich the genetic database of Indian populations.
