FREQUENCY OF ABO BLOOD GROUPS AND SECRETOR STATUS IN THE RAJPUT COMMUNITY OF HIMACHAL PRADESH

Abstract

Blood and saliva samples from 170 subjects of both sexes were collected from the community, Rajputs of Himachal Pradesh and were examined to determine their ABO and Rhesus blood groups by standard conventional methods and the secretor status was determined with Absorption elution technique. Out of 170 subjects 148 were secretors. A frequency distribution of  16.2%, 43.2%, 8.1% and 32.4% was observed for blood groups A, B, AB and O, respectively. The allelic frequencies were calculated to be 0.2, 0.24 and 0.56 for A, B and O alleles. The allele frequency for the secretor gene was found to be Se =0.64, and for non-secretor, se = 0.36. The allelic frequencies of blood groups were found to be in Hardy-Weinberg equilibrium.

The Study of secretor status provides a useful tool in medico legal cases for detection of suspected crime. This finding of distribution of blood groups, secretors and non-secretors in normal healthy population would be beneficial for further study, protecting at least partially, from certain malignancies or allowing them to have less aggressive disease, and this finding might be useful in enhancing further studies and research in this direction.
