A man having blood group O marries a woman having blood group A. What are the probable phenotypes of the offspring?

The genotype of the man is iiThe genotype of the woman can be IAIA or IAiIf the genotype of the woman is IAIA, thenIAIAx iiAll offspring would have genotype IAi. Therefore, all offspring would have blood group A.If the genotype of the woman is IAi, thenIAix iiOffspring would have genotype IAior ii.Therefore, the blood group of the offspring would be either A or O.
