Vedclass · Answer

(A) The $ABO$ blood grouping system is based on the presence or absence of two surface antigens on the red blood cells $(RBCs)$,namely antigen $A$ and antigen $B$.Individuals with blood group $A$ have antigen $A$ on their $RBCs$.Individuals with blood group $B$ have antigen $B$ on their $RBCs$.Individuals with blood group $AB$ have both antigens $A$ and $B$ on their $RBCs$.Individuals with blood group $O$ do not have either antigen $A$ or antigen $B$ on their $RBCs$. The '$O$' represents the absence of both $A$ and $B$ antigens,often referred to as 'zero' or 'null' in some contexts,indicating the lack of these specific surface antigens.
