Human blood type is a trait that can be expressed with multiple alleles. A and B are both dominant to O, but neither is dominant to the other. When A and B are both present in the genotype of an individual, both alleles are expressed. If a father has Type AB blood and a mother has Type O blood, what percentage of their children are expected to have Type O blood like the mother

0% of their children are expected to have type O blood like their mother.

Explanation:

We know that alleles A and B are both dominant, so when they are inherited, there is a codominance of them because the two of them express. In the case of the allele O, we know that is recessive in the presence of A or B. If we put this information in a Punnet Square, we know that all their children will be AO or AB, so none of their children will be type O blood.

    ║ A    ║  B║
