Different blood types have different genetic genes
Genetic blood type A can be A and A combined AA of both sexes, also may be one of the A gene and another of the O synthesis of AO, but both AA and AO, shown by the blood type, are A type, while O is recessive gene, not shown.
Type B blood genetic genes are similar to type A blood, some are BB, and some are BO, but they are all B type.
Type AB and type O blood genetic genes are consistent with the type of blood group shown, type AB is AB, and type O is OO.
Therefore, every parent is A or B blood type, their children may be A or B, but it may also be because of type O, A type or B type with recessive gene O, when the parent genetic O in maternal and genetic O in combination of OO that is O.
