Fig. 3

Variation in the sex ratio between Mesorhabditis strains. Boxplot representation of the sex ratio for 2 sexual species and 11 strains of auto-pseudogamous Mesorhabditis species, corresponding to 6 species. For each measurement, between 200 and 600 individuals were counted, 2 to 4 times independently depending on the strain (see corresponding values in Table S4). The sex ratio of asexual species is statistically different than those of the sexual species (GLMM model). The red dotted line corresponds to the highest sex ratio predicted by a game theory model for auto-pseudogamous species
