Detailed explanation-1: -When an antigen encounters the immune system, its epitopes eventually will react only with B-lymphocytes with B-cell receptors on their surface that more or less fit and this activates those B-lymphocytes. This process is known as clonal selection.
Detailed explanation-2: -clonal selection and differentiation of B cells activated by antigen leads to a a production of large quantities of the antigen initially recognized. The the cells with random antigen recognition receptors. See short lived plasma cells secrete antibody or the long lived a reference sites.
Detailed explanation-3: -Definition. The proliferation of B-lymphocytes and T-lymphocytes activated by clonal selection in order to produce a clone of identical cells. This enables the body to have sufficient numbers of antigen-specific lymphocytes to mount an effective immune response.
Detailed explanation-4: -The clonal selection theory proposes that antigen selects lymphocytes for activation from a population of cells precommitted to produce specific antibody. Implicit in this theory is that antibody-forming cells are monospecific and express cell-surface receptors capable of binding foreign antigens.
