Figure 6. Downregulation of the expression levels of painless exclusively in adulthood resulted in male–male courtship behavior.

(A₁ and A₂) Schematic representations of the experimental design used to manipulate the expression levels of painless. Flies were raised and maintained at different temperatures, as indicated. Average ChI of males of indicated genotypes reared according to the strategies shown in A₁ (B₁) or A₂ (B₂). Error bars represent SEM, and n>8 in each trace.
