To determine the possible blood types of children from a mother with type AB blood and a father with type O blood, we can use the possible alleles for each parent:
- The mother's genotype (AB blood type) can contribute either an A allele or a B allele.
- The father's genotype (O blood type) can contribute only O alleles (since type O means they have two O alleles).
Therefore, the possible combinations of alleles for their children are:
- A (from mother) and O (from father) → Child's blood type A
- B (from mother) and O (from father) → Child's blood type B
Based on this, the possible blood types for their children would be:
- A
- B
The blood types AB and O cannot occur from this combination:
- AB is not possible because there is no contribution from an O allele.
- O is not possible because an O blood type requires both alleles to be O.
Thus, the possible blood types for the children are:
- A
- B
Select A and B as the correct answers.
