Detailed explanation-1: -ABO blood grouping is based on differences in the type of glycoprotein (protein with carbohydrates attached) present on the surface of red blood cells. Type A individuals have type A glycoproteins; Type B individuals have type B glycoproteins; Type AB individuals have both; and Type O individuals have neither.
