Abstract:
In this study, allele frequencies were determined in a Peruvian population for application to human identification. A population of 601 unrelated individuals was analyzed (400 individuals with the GlobalFiler Express kit and 201 individuals with the VeriFiler Express kit). The locus with the highest power of discrimination (PD) was SE33 (0.9851, 31 alleles), while the least polymorphic locus was D22S1045 (0.75810, 11 alleles). The PE in a similar fashion ranged from 0.2421 (D22S1045) to 0.7818 (SE33). Under the assumption of independence, the combined PD was > 0.9999999999 while the combined PE = 0.9999999933. When comparing the population studied with different populations of Latin America, the greatest Fst genetic distance was obtained with a Venezuelan population (0.052), and the shortest distance was with a Bolivian and Peruvian population (0.004).
