Vedclass · Answer

(B) The thymus gland is a primary lymphoid organ that serves as the site for the maturation and differentiation of $T$-lymphocytes. In the absence of a thymus gland,the precursor cells (prothymocytes) that migrate from the bone marrow cannot undergo the necessary maturation process to become functional $T$-lymphocytes. $B$-lymphocytes mature in the bone marrow,and plasma cells are derived from $B$-lymphocytes; therefore,these would still be produced. Basophils are a type of granulocyte produced in the bone marrow. Thus,a mammal born without a thymus gland is unable to produce $T$-lymphocytes.

$A$ mammal born without a thymus gland is unable to produce which of the following?
