ABSTRACT
The allelic frequencies of 12 short tandem repeat loci were obtained from a sample of 307 unrelated individuals living in Macapá, a city in the northern Amazon region, Brazil. These loci are the most commonly used in forensics and paternity testing. Based on the allele frequency obtained for the population of Macapá, we estimated an interethnic admixture for the three parental groups (European, Native American and African) of, respectively, 46 percent, 35 percent and 19 percent. Comparing these allele frequencies with those of other Brazilian populations and of the Iberian Peninsula population, no significant distances were observed. The interpopulation genetic distances (F ST coefficients) to the present database ranged from F ST = 0.0016 between Macapá and Belém to F ST = 0.0036 between Macapá and the Iberian Peninsula.
