Df(1)16-129/Df(1)GA104 animals (in which fliI function is rescued by fliIFLI) are viable. Females produce a ventralised eggshell phenotype, which has 35% penetrance at 25oC and ranges in expressivity from fused dorsal appendages to no appendages at all. At 30oC, the penetrance is 99% and at 18oC the penetrance is 3%. Embryos produced from Df(1)16-129/Df(1)GA104 females (in which fliI function is rescued by fliIFLI) mated to wild-type males show cuticle patterning defects; expanded and fused ventral denticles.

fliIFLI Df(1)16-129/fliIFLI Df(1)GA104 individuals are 76% viable and 93% of survivors can fly normally.

Lethal in combination with Df(1)16-129.
