Question

If a child has blood type O and the child's mother has type

A, could a man with type B be the father? Why couldn't a
blood test be used to prove that he is the father? Explain.

Answer 1

Yes

Step-by-step explanation:

Each parent has O blood paired with A or B blood. Since the child does not have his blood type, a blood test would not be able to prove that he is the father.
