Serum factors and red cell enzymes in Carib and Arowak Indians from Surinam.

The results of the electrophoretic phenotyping of some genetic markers (haptoglobin, group specific component, transferrin, haemoglobin, glucose-6-phosphate dehydrogenase and 6-phospho-gluconate dehydrogenase) in two tribal Indian populations from Surinam are presented. Most of the gene frequencies fit well into the pattern of frequencies of the Amerindian Carib group. The finding of Hb AS and GDA in a small number of individuals, mainly Caribs, demonstrates some admixture by Negroes.
