The presence or absence of specific glycoprotein molecules on their cell membrane.
There are four major blood types
They are type A, type B, type AB, typeO.
The person 's blood type is determined by the presence or absence of two antigen A and B on the surface of red blood cells.
Type A: in this type there is presence of antigen A on red cells and antibody B in the plasma.
Type B: it has only the antigen B present on the red cells and antibody A in the plasma.
Type AB:it has both A and B antigen on red cells, both A and B antibody are in the plasma.
Type O: it has neither A nor B antigens on red cells but both A and B antibody are in the plasma.
74. D
Type A: in this type there is presence of antigen A on the red cells and antibody B in the plasma.
Type A blood group person can donate blood to type A and type AB.
75. C
Inappropriate or excessive immune response to antigen are allergies
