Table 1 Crosses between Mesorhabditis pseudogamous species. Summary of the crosses shown in Table S3. Cross outcomes are color-coded: blue for viable F2 progenies, black for absence of embryo production, light grey for production of dead embryos and light blue for mixed results, including the production of sterile F1s. * only one strain per species was tested. For each pair of species, the pair-wise distance between strains selected for Fig. 1 is shown.
