Is the father a type A son a blood type o a father and son?

Father and son cannot be determined, and the child's blood type depends on the blood type of both parents. The relationship between the blood type of the parents and the blood type of the child is: 1. The parents are A and B, and the child should be A or B or AB or O, 2. The parents are all Type A and the child is Type A or O, 3. The parents are all Type B, and the child is Type B or O, 4. The parents are all Type O, and the child is Type O, 5. The parents are all Type A, and the child is Type AB or Type A or Type B, 6. The parents are type A and O, and the child is type A or O, 7. The parents are type B and O, and the child is type B or O, 8. The parents are type B and O, the child is type A or B, 9, the parents are AB and A, the child is AB or A, 10, the parents are AB and B, the child is AB or B, 11, the parents are all AB, and the child is AB or A or B.

Let's put it this way, if both parents have blood type A, the child may be type A or type O.

If one parent is type A and one parent is type B or both have type AB, the child may be type A, B, AB or O.

If one parent is type A and one parent is type O, then the child may be type A, or type O, and if both parents are type O, then the child must also be type O.

In your case, there is a possibility, so if you want to be sure, you should do DNA.

Blood type A is actually blood type A, and the son is blood type O, which means that there is such a possibility that the father and son are father and son. To narrow down this possibility, it is necessary to know the mother's blood type. A person with blood type A and a person with blood type AB will never have a child with blood type O.

Paternal blood type A.

If the mother has blood type A, the son's blood type may be A or O;

If the mother has blood type B, the son's blood type may be A, B, O, or AB;

If the mother has blood type O, the son's blood type may be A or O;

If the mother has AB blood type, the son's blood type may be A, may be B, and cannot be O;

It also depends on the mother's blood type to judge, if the mother is type O, it is also possible that the child is type O, so it is recommended to do a paternity test, or take hair to do it.

To analyze the genotype, if the father is IAIA, then it is not. If the father is an iai, it also depends on the mother, and in this case, only if the mother has i, it will be the father and son.

This is not easy to judge, and it is best to take a paternity test.

Yes, unless your mother has AB blood type.

Possibly, DNA testing is recommended.

The father is O, the mother is A, and the child is what blood type.

Mom and Dad are Type A and Type O, and the baby can generally be Type A or Type O. Because the ABO blood group system is generally divided according to the presence of anti-A and anti-B antibodies in the serum, so both parents are type A, the child's blood type must be type A, if one is type O and the other is type A, the baby may be type O or type A, because ABO blood type has a certain genetic regularity. If both parents are type O, they can only give birth to type O children, and if one parent is type A and one is type AB, they can only give birth to type A or AB blood type.
