Which of the Following Should Be the Same in Identical

Question

Which of the following should be the same in identical twins?
A) the set of antibodies produced
B) the set of MHC molecules produced
C) the set of T cell antigen receptors produced
D) the susceptibility to a particular virus
E) the set of immune cells eliminated as self-reactive

Accepted Answer

Identical twins share the same genetic makeup, including the genes that encode for Major Histocompatibility Complex (MHC) molecules. MHC molecules are crucial for the immune system's recognition of foreign molecules, and since they are genetically determined, identical twins will produce the same set of MHC molecules.
