Question

Billie Sue was Manley's wife. She had type AB blood and both his parents AB. Jackie was type O and her husband Cal was type A. His parents were likewise AB. All four lived by themselves in a completely isolated research station on an artic island. Except for Abe the trader (type A), there were no visitors for 12 months, and at the end of the time both women had babies. In the confusion, the two infants got mixed up, and to straighten out the problem, the blood types of the babies were determined and found to be O for the boy baby and B for the girl.
