The anterior midline projection of the T3 [third thoracic] sternum, which usually forms a firm junction with the posterior midline of the T2 sternum at the T2 legs, lacks its usual point, leaving a small gap at the T2-T3 juncture. The anterior midline projection of the A3 [third abdominal] sternum, which usually forms a firm junction with the posterior midline of the T3 sternum at the T3 legs, has a reduced point, leaving a noticable gap at the T3-A3 juncture. This was the irradiated chromosome for the 33B . . . family of LG 3 crossover suppresors. Very fertile. No translocations found by cytology.
