Detailed explanation-1: -blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma. blood group B – has B antigens with anti-A antibodies in the plasma. blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma. blood group AB – has both A and B antigens, but no antibodies.
Detailed explanation-2: -Anti-A and anti-B are found in the sera of individuals who lack the corresponding antigens. They are produced in response to environmental stimulants, such as bacteria. These antibodies are produced after birth, reaching a peak at 5–10 years of age, and declining with increasing age.
Detailed explanation-3: -Blood group A individuals do not produce antibody B. Rather, they produce antibodies against the B antigen. This is because the immune system of blood group A individuals recognizes the B antigen as foreign and produces antibodies to attack it.
