I choo choo choose D. Ao and Bo can make OO. And I can mek you one hot pizza, eh? You lika da cheese? eh?

Isn't D?

If you think about it, if the father is AB and the mom O, it means that half of the offpring will be A and the other half B. Just do Punett Square!

Definetely the answer choice D cannot have a baby type O (phenotype), so the baby is ii for genotype.

In answer choice D :::
One parent is AB type (phenotype), which means genotypes IaIb

the other parent is type O (his phenotype), which means genotypes ii

Do punnett squares...or just look at it... cannot have type O baby
