Question

A mother and father are curious about the possibility of having children of certain blood types. After some testing, the doctor tells them there is no chance that either of them will ever have a child with type O blood, no matter their partner. He does assure them that all of their children will have the same blood type. On the other hand, none of the children will have the same blood type as either the mother or the father. What blood type will the children be?

Answer 1

The blood type that the children won't have O blood type because the doctor says so and the children will not have the same blood type. This means that the children's blood type will likely be type A or Type B.
