The ABO system consists of A, B, AB, and O blood types. People with type A have antibodies in the blood against type B. People with type B have antibodies in the blood against type A. People with AB have no anti-A or anti-B antibodies. People with type O have both anti-A and anti-B antibodies.
The ABO gene has three possible traits. A, B, or O. A and B are dominant, O is recessive. This means you only need on ABO gene that is type A for you to express type A blood, It also means you only need on copy to be type B for you to express type B blood.
