Fig. 1From: Coevolution of female and male genital components to avoid genital size mismatches in sexually dimorphic spidersTheoretical relationships between sexual genital size dimorphism (SGD) and female-biased sexual size dimorphism (SSD). The upper figures are the expected relationships of SGD to SSD, the lower figures are the predicted patterns of female (solid line) and male (dashed line) genital size on SSD. Shaded area indicates theoretical fits of genital sizes. Values that fall out of this area would imply genital size mismatchBack to article page
