Final answer:
The offspring will not have type AB blood.
Step-by-step explanation:
The probability of their offspring having type AB blood can be determined by looking at the parents' blood types. The mother has type AB blood (IAIB) and the father has type O blood (ii). To determine the percent chance, we need to consider the possible genotypes of the offspring. When two parents with AB and O blood types have children, the children can be type A, type B, or type AB. However, in this case, the father has type O blood, which means he does not have the A or B alleles. Therefore, the only possible genotype for the offspring is IAi, which would result in type A blood. So, there is 0% chance that their offspring will have type AB blood.
