The most popularly known blood grouping is the ABO grouping. It is named ABO and not ABC, because “O” in it refers to having:

1. overdominance of this type on the genes for A and B types.
2. one antibody only - either anti - A or anti - B on the RBC.
3. no antigens A and B on RBCs.
4. other antigens besides A and B on RBCs.

Correct answer: no antigens A and B on RBCs.

Solution

The ABO system includes A, B, AB, and O blood groups. Type O is named for the absence of A and B antigens on the surface of red blood cells, which is why it is not called ABC.
