FIG. 1. Effect of manipulating paternal density on offspring developmental traits. Offspring sired from high-density males are shown in black; offspring sired by low-density males are shown in gray. Large points in panel (a) show the probability (mean 6 SE) of hatching into a larva with a normal phenotype. The small points linked by lines are the hatching probabilities for each trial, as estimated by the mixed-effects logistic model. The box and whisker plots in panel (b) represent raw values of time from fertilization to hatching. The thick lines are medians, boxes are 0.25 and 0.75 quantiles, and whiskers indicate maximum and minimum values accounting for outliers (circles).
