Answer:
Row 1: Any blood type except AB
Row 2: Blood type A/AB
Row 3: Any blood type except AB
Row 4: Any blood type
Row 5: AB/B
Explanation:
1. If the blood type was AB for the first one (two dominant alleles) then O could not appear as it is recessive.
2. The blood type must contain at least one A allele as AB is obtained from I^A and I^B (already provided by the mother).
3. Once again, the blood type must carry at least one recessive O allele for the O blood type to occur in this child.
4. As long as the blood type either carries a recessive O or another B, the blood type will result in a B.
5. The blood type of the father must contain at least one B for the child to have a B blood type.
