      Type AB blood is rare – it’s found in less than five percent of the population. And it is the newest of the blood types. Until ten or twelve centuries ago, there was no Type AB blood type. Type AB resulted from the intermingling of Type A with Type B. Type AB is the only blood type whose existence is the result of intermingling rather than environment.
