Biology Question on Principles of Inheritance and Variation
Blood group agglutinogens A and B are found:
A
(A) In plasma
B
(B) On WBC's
C
(C) On RBC's
D
(D) On blood platelets
Answer
(C) On RBC's
Explanation
Solution
Explanation:
Agglutinogens A and B are the glycoproteins found on the surface of red blood cells. These are also known as A and B antigens and on the basis of these antigens, four blood groups are classified as A,B,AB and O. Antigens A and B bind to specific antibodies called agglutinins and this process is called agglutination. In blood type A, antigen A is present on RBCs while in blood type, antigen B is present on RBCs. In blood type AB, both antigens A and B are present on RBCs and no antigen is present on RBCs in O blood type.Hence, the correct option is (C).
