Blood Types Problem Set

Problem 1: Is a type O possible in this situation?

Could you please help me? I have a question that is NOT a homework question. I am a Junior in High School. "Could a man with type B blood and a woman with type AB produce a child with type O blood?" I think not, because type O is recessive, and the B's seem to be dominant. My cousin thinks yes. Thank you for your help. -- Vicki
