Fig. 4. debcl genetically interacts with dark. (A-C) Adult wings are normal in morphology and appearance at the time of eclosion (D₀). (D-F) Wing blemishes are progressive in nature and more severe in debcl, dark^CD4 double mutants (E,F) than in dark^CD4 single mutants (D), seen here in 14-day-old animals. (G) Histogram quantifying the severity of wing blemishing. The incidence of wing blemishing is expressed as a percentage of the wing afflicted with melanized spots over the entire wing region. Error bars show ±s.d. (n=10).
