Someone in the maternity ward has removed the ID bracelets of three babies. One of the mothers of the babies has panicked and wants to ensure that she gets her real baby. As a doctor, you have decided to do a blood test of the three babies and the parents. The babies’ blood types are A, AB, and O. The husband of the mother is type O, and she is type AB. Provide an explanation to the parents as to which baby must be theirs.

Respuesta :

Answer: Baby with type A is the mother's baby

Explanation:

Father has blood type O (father received an O from each parent making him OO)

Mother has blood type is AB

Therefore the possible combinations of the child's blood type are AO and BO. Since A and B are dominant blood types and O is recessive- the baby can have blood type A if they received AO from their parents or B if they received BO from their parents.

Of the three babies with blood types O, AB and A, baby with blood type A belongs to the mother.
