At a hospital, a man is admitted who needs a blood transfusion. He knows his parents' blood types are B and A. A nurse wants to give the man a transfusion with AB blood. Should you let the nurse give the man the transfusion?

The answer would be  - no.

Explanation:

A person who needs the blood transfusion and knows that his parent's blood group are A and B. Child of parents with A and B blood group might have any type of blood group A, B, AB, or O. So there are 75% chances that the person will show Blood incompatibility as there will be chances of making antibodies against antigen present the blood cell.

In this, case you can give the person a transfusion with O or find the blood group and then give a transfusion of particular blood group blood.
