Q. No.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.
other antigens besides A and B on RBCs
2.
over dominance of this type on the genes
for A and B types
3.
one antibody only- either anti A or anti-B
on the RBCs
4.
no antigens A and B on RBCs
for A and B types
on the RBCs
