which set of parents could Not be the parents of a child with type O?
A father type A, mother type O
B father type A, mother type B
C father type B, mother type O
D father type AB, mother type O
E father type O, mother type O

Shouldn't answer be B?
 
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
