anwiii 17 Report post Posted June 4, 2011 i am hesitant to answer this question, but yes, it's impossible to be blood type A if both parents are blood type B. it's also impossible to be AB.if you are the child and know for a fact that one of your parents are B, then the other parent is either A or ABhope this helps and wasn't too disappointing....
