Since the mother's type is recessive O, the man's blood type A would be dominant. And because none of the children gained B or O blood types, it is likely the father only has A. This indicates homo-zygous (same) genotype, thus meaning his blood type is AA.
the reason for the dash between homo-zygous is because Brainly tagged it as inappropriate?
