Abstract:
Brazil is the result of interethnic crosses of European, African and Amerindian populations. Allelic frequencies for seven STR loci (TH01, TPOx, CSF1PO, vWA, FES/FPS, F13A1 and CD4), obtained from a sample of 70 individuals identified as Afro-Brazilian and 150 as mulatto, are presented here. Based on the frequencies of these genetic markers, estimates of interethnic admixture showed 62%, 26% and 12% of European, African and Amerindian contribution, respectively, for the mulatto sample and 37% and 63% of European and African contribution, respectively, for the Afro-Brazilian sample.
