Fig. 6From: Natural and experimental evolution of sexual conflict within Caenorhabditis nematodesSperm competitive ability for two lines of high- and no-competition C. elegans experimental evolution lines. Format is the same as Figure 2, except that here males from each experimental treatment are compared to a standard GFP-marked male and significance testing is therefore based on performance differences between experimental evolution treatments. Error bars represent approximate standard errors based on among-plate estimates of mating success. ****p < 0.0001Back to article page
