Allelic frequencies with 23 autosomic STRS in the Aymara population of Peru.

Population data of the Aymara in the province of Puno were established for 23 autosomal STR markers. DNA was obtained from unrelated individuals (n = 190) who reside in three areas of the Floating Islands of Lake Titicaca, residents on the border with Bolivia and residents who are not from the border with Bolivia. The PENTA E marker presented the highest PD (0.9738), PIC (0.8793), and PM (0.7847) values. The combined PD was greater than 0.99999999 and the combined PE was 0.99999994. The largest distance, based on Fst values, was between the Aymara population and the Ashaninca population (0.04022), and the smallest distance was with the populations of Bolivia (0.00136) and Peru (0.00525).

Population genetic study of a Peruvian population using human identification STRs.

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).
