julia-pushkina [17]

Answer:

Yes

Explanation:

Yes, it is possible. If the woman would have blood AO and the father BO. This would mean there is a 25% chance the child could be OO blood. They would receive an O allele from their mom and an O allele from their dad, in all other cases the O allelle is recessive so AO would be A blood type and BO would be B blood type. AB would be type AB.

    B         O                                      

A   AB     AO                              

O   BO    OO
