Vedclass · Answer

(C) The Assertion is correct because the $ABO$ blood group phenotype is determined by the presence or absence of specific antigens ($A$ and $B$) on the surface of $RBCs$.The Reason is incorrect because these antigens are not found on glycophorin. Instead,they are attached to the lipid bilayer of the $RBC$ membrane via glycolipids or glycoproteins. Glycophorin is a specific membrane protein,but it is not the primary carrier for $ABO$ blood group antigens.

$A$: Blood group phenotype is controlled by the presence or absence of antigens present on the surface coating of $RBC$.
$R$: These antigens are of three types and are found in the oligosaccharide-rich head regions of a glycophorin.
