Abstract
Phenotype and gene frequencies of blood groups, plasma proteins and red cell enzymes (23 systems) are examined in two tribal and one low social class urban population of Orissa, India. Genetic heterogeneity is suggested not only between the tribal and urban populations but also between the tribal groups. The gene frequencies of tribal populations indicate a genepool with an ancestral component from the populations of north-east India with some mongoloid affinity, but it seems that there has also been some gene flow from them into the urban population.
