In a Correlated response of male perception (female/total number of mountings), represented by model residuals. Plotted is the mean for each selection treatment ± 1SE based on means for the four replicate lines. Male perception responded to selection on males, with up-selection leading to a decrease in perception (i.e. increased perception error), but showed little response to selection on females. In b scores for male perception are plotted against scores for male (filled triangles) and female (open triangles) lifetime reproductive success for the male selection lines
