As we know A and B antigens are inherited as dominants characters

So:
1-Persons with blood group A may be AA or AO.
2-Persons with blood group B may be BB or BO i.e. genotype
3-Persons with blood group AB is only AB
4-Persons with blood group O is only OO

See figure below

For example: If a male with blood group A married a woman with blood group B
the blood groups of their children may be A, B, AB or O

This example is shown in the figure below:
