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.
巴西是欧洲、非洲和美洲印第安人种群族际通婚的产物。本文呈现了从70名被认定为非洲裔巴西人和150名被认定为混血儿的个体样本中获取的7个STR基因座（TH01、TPOx、CSF1PO、vWA、FES/FPS、F13A1和CD4）的等位基因频率。基于这些遗传标记的频率，族际混合估计显示，混血儿样本中欧洲、非洲和美洲印第安人的贡献分别为62%、26%和12%，非洲裔巴西人样本中欧洲和非洲的贡献分别为37%和63%。
