Q. In which blood group antigens are absent?

Punjab PMETPunjab PMET 2003

Solution:

Person with blood group 'O' has no antigen on his $RBC$ but has both the antibodies (i.e., a and b) in his plasma. Whereas a person with blood group ' $AB$' has both antigens but no antibody. Due to this blood group ' $O$' is universal donor and blood group 'AB' is universal acceptor.
