“…Our results, together with the recently determined chromosom,al location of the T-cell -chain gene (26,27), show that the known Ig-like genes (a, 13, and y), which rearrange in T cells, are each located on a different mouse chromosome: a on 14, on 6, and y on 13. The three Ig gene families are similarly located on different mouse chromosomes: the genes for H, K, and chains are on chromosomes 12, 6, and 16, respectively (22)(23)(24)(25).…”
