The thymus provides an inductive environment for T lineage commitment at which of the following loci?

The thymus provides an inductive environment for T lineage commitment at which of the following loci? Correct Answer Gamma-delta and alpha-beta TCR 

Thymus is known as a site for the development and maturation of T lymphocytes. This is a primary lymphoid organ that provides a sufficient environment for lineage commitment of T lymphocytes. This process is mediated by T cell receptors (TCRs) at two major loci which are gamma-delta TCR locus and alpha-beta TCR locus.
