Number of germinated conidia after transfer from one Petri dish to another (estimated over circles of 3 mm in diameter). Two independent replicates were generated. For each replicate, three areas on the plate were counted. The error bar represents the standard deviation calculated from these three counts. Blue bars: female-fertile wild-type strains (S1, S2 and S4). Green bars: female-sterile evolved strains (S1-B20, S2-A20 and S4-B20). Orange bars: mixtures of female-fertile wild-type strains and female-sterile evolved strains (S1+S1-B20, S2+S2-A20 and S4+S4-B20).
