Explanation

Antigens on the surface of red blood cells determine blood groups and are inherited genetically. The ABO and Rh blood group systems are based on specific antigens present on RBCs. Hemoglobin is the oxygen-carrying protein, antibodies are in plasma, and 'blood groups' is the result, not the factor.
