Descrição: Data on 15 genetic systems (the hemoglobins, five serum proteins and nine erythrocyte enzymes) are reported for five populations of Brazilian Cayapo Indians. The haptoglobin, Gc and acid phosphatase frequencies are within the most common range found in South American Indians. The phosphoglucomutase gene PGM₁1 presents a somewhat low value, and in contrast with two other studies there is some variation in the ceruloplasmin system. An unusual finding was the occurrence of one individual with a persistence of fetal hemoglobin. No variation was observed at the transferrin, albumin, glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, adenylate kinase, lactate dehydrogenase, malate dehydrogenase, "indophenol oxidase", and adenosine deaminase systems. Using blood group data reported previously and those from the haptoglobin system pairwise 6-locus genetic distances for four of these populations were computed. Their average is intermediate compared with those from three other South American Indian tribes which as the Cayapo have not been much disturbed by non-Indian influences. A summary of parentage exclusions using the information presented here and that related to the secretor and blood group polymorphisms is also given. The frequency of these exclusions (23%) is about double that observed in another tribe living at this same cultural stage.
