What is the abo blood classification based on? a. antibody on the red blood cell b. antigen in the blood c. antigen on the red blood cell d. hemoglobin in the blood

The correct answer is C) Antigen on the Red blood cell.

The classification of ABO blood grouping is based on the presence of corpus Antigen on the surface of red blood cells.

There are four blood types (A, B, AB, O) in this classification that are determined by three alleles of ABO gene in a population.

On the surface of RBA, blood type A has Antigen A, blood type B has Antigen B, and blood type O has no antigen.

Thus, C) is the right answer.

The ABO blood group is classified on the basis of antigen present on the surface of red blood cells.

Further Explanation:

A blood group system or ABO blood groups are classified on the basis of the inherited characteristics of the erythrocytes (red blood cell). It is determined by the presence of type A and type B antigen on the surface red cells. On the basis of that, the individual may have type A, B, O and AB blood group.

The blood groups were first discovered by Karl Landsteiner in 1901. He was an Austrian immunologist. The people with type A antigen will have type B antibodies in their serum. If type A blood is transfused to the individual with type B blood group, the blood will show coagulation because type B antigen will react with type B antibodies. The individual with type O blood group does not possess both types of antigen, whereas type AB possesses both the antigens. Blood group O is the most commonly occurring blood group type across the world.
