Figure 4.
Combined effect of dsxRNAi and nutritional quality on shape in D. gazella. Shape scores [42] represent projections of the shape data onto the vector defined by sexual shape dimorphism of animals reared on a high-quality diet. Small values indicate a more ‘female-like’ shape while larger scores indicate more masculinized morphology. Sketches correspond to the sex-specific mean shapes of control and dsxRNAi individuals for horn and fore tibia morphology (see electronic supplementary material, figure S3 for a principal component analysis).
