Fig. 6. heph⁰³⁴²⁹ partially rescues the fng^D4 margin loss phenotype. (A) An example of a wing from fng^D4/+ male. Most or all of the wing margin is missing. This phenotype is partially rescued in fng^D4/heph⁰³⁴²⁹ male (B) or in N^Ax-1/+; fng^D4/+ transheterozygous females (C). All flies were cultured at 25°C. The fng^D4 phenotype is variable and these images are representatives of the most common phenotype observed in flies of each genotype.
