Figure 2.

Effects of Foxo^RNAi, InR1^RNAi, InR2^RNAi and InR1 + 2^RNAi on the largely nutrition-insensitive scaling relationship between body size and male genitalia length. Shown are control-injected (grey) and knockdown (red) individuals. (a) Foxo^RNAi resulted in a significant decrease in the slope of the body size-genitalia allometry, while (b) InR1^RNAi, (c) InR2^RNAi and (d) InR1 + 2^RNAi significantly reduced genitalia size across all body sizes. The same control individuals are shown across all four panels. (Online version in colour.)
