A study on blood groups and serum proteins in Bengalee populations of Calcutta, India.

The genetic polymorphisms of two blood groups (A1A2B0, Rh-D) and two serum proteins (HP, TF) were investigated in five endogamous caste groups of Bengalee Hindu population living in Calcutta. The distribution of A1A2B0 and Rh-D blood groups in all the caste groups showed an oriental pattern with high B and Rh-D+ frequencies, while for the haptoglobins a very low frequency of HP1 was seen in all the caste groups, except the Vaidya. For transferrin types the absolute predominancy of TFC in all the caste groups was noted.
