which ismost common blood group?
The studies show that the most common blood group is O. Being universal donor, O group is most common group while AB- is most rare group.
Dear Candidate,
Most common blood type is O ( around one third of the population ). Then the B was second most common blood type, 32% approx. followed by A at 22.88% while AB was the least prevalent group at 7.74%. 94.61% of the donor population was Rh positive and the rest were Rh negative.
Hope this helps. Thank you.
