Answer:

The correct answer is e. all of the above

Explanation:

A person can only have two allele of a character, therefore, the genotype of a male parent can be IBIB or IBi and the genotype of female parent can be IAIA or IAi. Therefore during gamete formation, all allele will segregate and assort independently.

So all the possible combinations are possible that are IAIB, IAi, IBi or ii because all the allele can be present in the two parents in which one have A blood group and another have B blood group.

Therefore their children could have A, B, AB, or O blood group so the correct answer is e. all of the above.
