Embryonic lethal. Addition of P{mor+11.8} rescues lethality somewhat, to larval lethality. Remaining lethality is rescued by P{CG4287-CG5516-(Rbf2).S} but not P{(CG4287)-CG5516-Rbf2.S}, and is hence attributable to the deletion of CG4287.
The ends of the two P{lacW} elements are still intact and one mini-white is still present in this background (from eye color and PCR data).
