A blood type O child would be impossible from this match. An AB parent must give an A allele or a B allele, and both alleles are dominant. If mother is homozygous B (meaning both alleles are B's), and father is AB, child can be either B or AB. If mother is heteroygous B (meaning one B allele and one O allele), and father is AB, the child can be either A, B, or AB.
