Summary of RNAi phenotypes, survival, and penetrance as a function of RNAi target and sex

RNAi target	Survival (%)	Representative phenotype (sex: penetrance %)
		Appendages (legs and wings)	Body segments	Eye/head development
hh	48	Narrowed femur and tibia (male: 71.1; female: 78.3)	Slight anterior bulge in pronotum (male: 26.3; female: 21.7)	Not measured
smo	32	Severely narrowed femur and tibia (male: 87.5; female: 82.4)	Prominent anterior bulging in pronotum (male: 84.3; female: 82.4)	Reduced eyes associated with overproliferation of lateral/posterior head (male: 85.7; female: 69.2)
ptc	57	Thickened, widened femur and tibia (male: 100; female: 92.3)	Partial anterior depletion in pronotum (male: 85.7; female: 69.2)	Malformation of head, especially anterior to eyes (male: 78.6; female: 53.8)
