Tribal Non-Tribal Bengaluru Human blood polymorphic systems are important biochemical markers in anthropological surveys especially in relation to disease distribution. G-6-PD deficiency and certain haemoglobinopathies are known to confer a selective advantage to the subjects against falciparum malaria.
