Abstract

This study presents genetic diversity at 22 autosomal STR loci (extended CODIS STR) in the population of Rajasthan. It provides an allelic database of this population for the purpose of forensic inference. 595 unrelated healthy individuals residing in the state were randomly selected from the routine casework of the laboratory. Compliance of ethical standards was ensured during the collection of blood samples. The allele 15 of locus D22S1045 was found to be the most frequent allele among all the studied genetic markers. The matching probability was found to be 1.80 × 10−26 at all the studied markers. The loci Penta E and TPOX were found to be highest and least forensic importance respectively, among all the studied loci. The heterozygosity ranged from 0.711 for locus TPOX to 0.926 for the locus Penta E. The discrimination and exclusion power were found as 1 and 0.999999998292 respectively at all the studied loci. Overall, the highest polymorphism was observed 0.907 for locus Penta E among the studied markers in the population of Rajasthan. In population differentiation test, the population of Rajasthan showed a greater genetic affinity with north-western and central Indian populations than southern and eastern Indian, as well as East Asian populations.
