Figure 4 – Comparison of for expression between sexual and asexual populations, in relation with fertility. A) Variations in the for gene expression between sexual and asexual populations. B) Individual for expression according to egg load in sexual (black) or asexual (red) females. Black and red lines corresponded to the values predicted by the model in sexuals and asexuals, respectively. C) Individual for expression according to the number of eggs laid in asexual females. Circles represent data measured in females: 17 asexuals (red) and 17 sexuals (black). Expression of the gene foris indicated relatively to the median individual.
