Abstract
The frequencies of ABO and Rhesus (D) blood groups and influence of gender were determined on prevalence of these blood groups. Blood group B was found to be the most frequent (38.004%). The frequency of blood group O was 28.755%, for group A 23.260% and for group AB 9.981%. In Rhesus blood grouping system the frequency of Rhesus (D) positive was 89.094%. Gene frequencies with respect to ABO and Rhesus (D) negative were different as for only ABO and ABO along with Rhesus (D) positive. The trend can be shown with a general formula O > B > A > AB. Group A positive (24.299%, 6.542% respectively) and negative (21.777%, 4.000% respectively) was more frequent in females as compared to males. In contrast group AB was more prevalent in males (12.444%) as compared to females (9.345%). There was a real preponderance of the blood group B over the blood groups O, A and AB as well as Rh (D) positive over Rh (D) negative. Predominance of blood group A in women was also reported. Group A along with Rhesus (D) negative group was more frequent than group B along with Rhesus (D) negative.
