Sexual size dimorphism under selection (IMAGE)
Caption
Sexual size dimorphism under selection. Female seed beetle Callosobruchus maculatus (with darker colouration) and two males that differ in body size. In our study we used artificial selection to increase sexual size dimorphism, and the beetles in the photo show the variation in sex difference in size after selection.
