Explanation:
Detailed explanation-1: -The need for O+ is high because it is the most frequently occurring blood type (37% of the population).
Detailed explanation-2: -The gene for type O is ‘recessive’, because if you have one gene for O and one for A, then you still end up with A antigens on your cell membranes, and the same goes for O and B. In order to be group O, you need both parent cells to be O. But group O is still more common simply because it is the ancestral form.
