A woman takes a man to court claiming that he is the father of her son and that the man should be required to pay child support. The man’s blood type is A, the woman’s is AB and her son’s blood type is B. Is it possible for the man to be the boy’s father?

No

Explanation: Since when a child is born it has DNA from both. As an example, the mom has brown hair, father has blonde hair, the child would take the DNA for the type of hair they get, either blonde or brown. So since its blood, the fathers is A, and the boy's is B, therefore it didn't take any of their DNA's so nope, he isn't the father.
