Some T cells express $\gamma$:$\delta$ T-cell receptors rather than $\alpha$:$\beta$ T-cell receptors. The organization of the $\alpha$ locus and the $\delta$ locus helps to ensure that each T cell cannot express both types of T-cell receptors. The mechanism involved is that:

The rearrangement of the T-cell receptor α gene (represented here as F1F1F1S1αF1F1F10) involves deletion of the δ locus (F1F1F1S1δF1F1F10) on the same allele, ensuring that a T cell cannot express both α:β and γ:δ T-cell receptors.
