Answer 1

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:

1. A (from mother) and O (from father) → Child's blood type A
2. 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.
