Allele frequencies of six short tandem repeat (STR) loci were determined in a Caucasian urban sample of La Plata city and three Amerindian sample populations of Argentina. Allele frequencies showed differences between urbans and Amerindians, and among Amerindians as well. The degree of genetic differentiation of subpopulations was mainly due to the Amerindian contribution. Mapuche, Mocovi, and pooled Amerindian populations showed little evidence of HW disequilibrium, and association of alleles. In the urban sample, there is no evidence of population substructuring. Forensic probabilities of exclusion and matching showed high differences between the population groups. Finally, La Plata sample did not show differences with Caucasians from other geographic regions.
