Defensive (P1) and offensive (P2) sperm competitiveness of gene knockdowns and controls. Mean P1 (A) and P2 (C) for each KD (color coded) and wild-type control (red) are shown with error bars indicating the standard error of the means. Gene KDs are color coded based on their selection regime (Blue: selectively constrained, Green: Relaxed purifying selection, Purple: Positive selection, Black: Unknown). Two genes show both green and purple because they had population specific selection regimes. B Boxplot showing differences in overall effect of KDs on P1 for selectively constrained and relaxed genes. The mean and median P1 values are shown as circles and lines within the box, respectively. ***P < .001, **P < .01, *P < .05
