Biology help please!

The mother has blood type O, the father has blood type AB, and the baby has blood type B. What is the mother's genotype? The father's genotype? the baby's genotype?

O is recessive, so it would be uncommon for the mother to pass on this gene unless the father was also O. The mother must be double recessive O and the father dominant AB and so B is dominant in the child
