Mother type A, father type B, then what blood type would I be?

This is divided into many cases, because type A and type B are dominant genes. Assuming that the dominant gene of type A blood is A, the dominant gene of type B blood is B, and the recessive gene is O, then AA and AO are both type A blood, BB and BO are both type B blood, AB is both type AB blood, and only OO is type O blood, then if

1: The blood group genes of both parents are AA and BB, so the child must be AB blood group.

2. If the blood group genes of parents are AA and BO, then the child may be half AB blood and half A blood.

3. If the parents' blood type genes are AO and BB, then the child's blood type may be half AB and half B,

4. If the parents' blood type genes are AO and BO, then the child's blood type can be AB, A, B and O, and the four possibilities are the same, that is, there is a 25% possibility.
