Subsequent genetic experiments, including variants of hT2 with new morphological mutations induced by mutagenesis, elucidated its genetic structure as a reciprocal translocation and its meiotic pairing and segregation behavior. It is comprised of two half-translocations: hT2(I), which pairs with and disjoins from the normal LG I in hT2 heterozygotes; and hT2(III), which pairs with and disjoins from the normal LG III in heterozygotes. In simple terms, the mutagenesis event that produced hT2 cleaved LG I between unc-101 and unc-59, and LG III between dpy-17 and unc-93; in hT2, the resulting rightmost portion of LG III is translocated to the rightmost portion of LG I to form hT2(I), and the leftmost portion of LG I is translocated to the leftmost portion of LG III to form hT2(III) (see Figure 1).
