From: Meiotic drive changes sperm precedence patterns in house mice: potential for male alternative mating tactics?

Fig. 1

Sperm precedence patterns change with male genotype combination. Shown is the paternity share of the second-to-mate male (P2). P2 was below 0.5 (first male precedence) when two +/+ males competed, but above (second male precedence) when two +/t males competed. Boxplots and circles show the raw data, with area size corresponding to the number of observations. Red circles depict sperm competition trials in which the first male ejaculated twice; the green circle shows a trial with two ejaculations by the second male. Blue diamonds and error bars show the model predictions and 95 % confidence intervals from a GLMM accounting for other fixed effects (see main text)
