Evolution of fecundity and fertility. Bars represent the average individual fecundity (number of embryo progeny; panel A) or fertility (number of adult progeny; B) before or after day 4 of the life-cycle, the day passaging occurred during experimental evolution. Empty bars show results for samples of the ancestral populations (G0) and grey bars for derived populations after 100 generations of experimental evolution (G100). Individuals were enforced either to self or to outcross with tester males. Hermaphrodites came from male-hermaphrodite populations, which had maintained stable 50% of outcrossing during experimental evolution. Females came from male–female populations. Error bars denote one standard mean error among the three blocks done. Significant evolutionary responses (differences between G100 and G0) are indicated with: +, p < 0.1; *, p ≤ 0.05, ** p ≤ 0.01; ***; p ≤ 0.001. Y-axes are truncated for clarity.
