Blood types are inherited. But there is not a dominant type. When the

genes determine the blood types BOTH traits are exhibited, so the blood

type becomes a mixture of both traits. Example, if a parent is type A and the

other is type B, then the child will get a blood type called AB because both A

and B are both dominant (co-dominant.)

5. A woman with a blood type of O is accusing a man with a blood type of AB of being the father of the child
