Study on the distribution of MN blood group system in the six caste populations of Tirupati (South India).
The MN blood group distribution was analysed in 600 individuals belonging to six caste groups of Tirupati (Andhra Pradesh, South India). the MN blood groups values are as follows: M = 36.00 to 45.00%, N = 10.00 to 16.00%, and MN = 43.00 to 51.00%. The frequency of the M-gene varies from 0.6050 to 0.6650, and that of the N-gene from 0.3350 to 0.3950.
