    Which of the following statements is (are) true of a T cell that expresses two α chains (and thus two different T-cell receptors) as a result of ineffective allelic exclusion of the α chain during rearrangement? There will be two unique TCRs on the surface of this T cell. Engaging either of the T-cell receptors on MHC molecules of the thymic epithelium will result in positive selection. If either T-cell receptor binds strongly to self-peptide presented by self-MHC molecules, the...
