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.
There is a separate gene for each part of the blood type we are discussing here. The ABO gene is in charge of the A and O (and B and AB) parts of blood type and the RHD gene is responsible for the positive and negative parts.
