Question

On what basis can blood grouping be done

Answer 1

Answer:

Your blood type is based on whether or not certain proteins are on your red blood cells. These proteins are called antigens. Your blood type (or blood group) depends on what types your parents passed down to you. Blood is often grouped according to the ABO blood typing system.
