Abstract
Significant variation in the frequency of Esterase [Es] D isoenzymes was found in 1070 individuals belonging to 8 South American Indian tribes. The Es D1 allele shows frequencies varying from .36-1. A region of low prevalence of this allele seems to exist in northern Brazil, involving the Parakanan, Gorotire, and Kraho. The intratribal variation observed in 8 Yanomama villages located in Brazil was not exceptional.
