Detailed explanation-1: -Thus, in humans, type O has neither antigen but both agglutinins, type A has A antigen and anti-B agglutinin, type B has B antigen and anti-A agglutinin, and type AB has both antigens but neither agglutinin. See also blood typing.
Detailed explanation-2: -Type A blood cells are covered with A agglutinogens, type B have B agglutinogens, type AB have both A and B, and type O blood have none.
Detailed explanation-3: -Whereas, a type O blood sample will not agglutinate with either type A or type B antibodies as type O blood contains no antigens.
Detailed explanation-4: -In blood type O, there are no agglutinogens on the surface of the red blood cells.
Detailed explanation-5: -When type A agglutinogen is not present in a person’s red blood cells, antibodies known as anti-A agglutinins develop in the plasma. Also, when type B agglutinogen is not present in the red blood cells, antibodies known as anti-B agglutinins develop in the plasma.
