The T-cell receptor (TCR) genes (alpha, beta, delta, and gamma) are comprised of numerous, discontinuous coding segments that somatically rearrange to produce heterodimeric cell surface T-cell receptors, either alpha/beta (90%-95% of T cells) or gamma/delta (5%-10% of T cells).
An individual heterozygous at two loci, which are on different chromosomesâletâs call them the T and Z genes, and the possible alleles t and t', z and z'âcan produce 4 types of sex cells, or gametes: tz, tz', t'z, and t'z'.
