GENE FREQUENCY AND PERCENTAGE DISTRIBUTION OF ABO BLOOD GROUPS IN SCHOOL CHILDREN OF VISAKHAPATNAM

Dr. R. Ravi Sunder, Dr. Neelima. P

Abstract :

To determine the gene frequencies and percentage distribution of ABO blood groups in school children of Visakhapatnam. 600 students of a school participated in the study. Reports of 522 students were evaluated and the remaining was discarded. Gene frequencies were calculated using Hardy-Weinberg principle and Bernestein method. The most common blood group from the study was O+ve with 48.85% distribution followed by B+ve with 30.45% distribution, A+ve with 16.85% distribution and AB+ve with 2.87% distribution. B-ve blood group constituted 0.57% and the least percentage of distribution from the study was O-ve which was 0.38%. The gene frequency of O group was 0.699, A group 0.110 and B group 0.191. As there are variations in the geographical distribution of ABOblood groups, the results were compared with a study made from other region of Andhra Pradesh and p value was 0.4057 which is not significant statistically indicating the similar type of distribution in Visakhapatnam too.
