Detailed explanation-1: -There are 4 main blood groups defined by the ABO system: 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.

Detailed explanation-2: -Red blood cell antigens determine your blood group The antigens expressed on the red blood cell determine an individual’s blood group. The main two blood groups are called ABO (with blood types A, B, AB, and O) and Rh (with Rh D-positive or Rh D-negative blood types).

Detailed explanation-3: -A blood group or blood type is a blood-classification, categorized on the basis of presence and absence of antibodies and inherited antigenic particles on the surface of RBCs. Important MCQs for NEET Biology: MCQs on Life Processes.

Detailed explanation-4: -ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells. Persons may thus have type A, type B, type O, or type AB blood.

Detailed explanation-5: -The ABO group of a person depends on whether his/her red blood cells contain one, both, or neither of the 2 blood group antigens A and B. There are, therefore, 4 main ABO groups: A, B, AB and O. Antibodies (agglutinins) for the antigens A and B exist in the plasma and these are termed anti-A and anti-B.
