What is Mrs. Canal's genotype? How do you know?
IᴬIᴬ , because Rosalind is A
Iᴮi because Biff is AB
Iᴬi because Greg is type O

Two parents think their baby was switched at the hospital. The mother has blood type O, the father has blood type AB and the baby has blood type B.
Complete a punnett square and then answer the question. Was the baby switched at birth? (Do they have a baby that is not theirs? )
No, the baby is type B which is possible when Dad is AB
No, the baby is theirs - it has type B just like the mom
Yes - neither parent is type B so it must have been switched
