From: The tempo and modes of evolution of reproductive isolation in fungi
Evolution of reproductive isolation in Microbotryum (Basidiomycete). (a, b) show the evolution of assortative mating between sporidia, and hybrid inviability during F1 hybrids’ hyphal growth, respectively. (c, d) describe F1 hybrid inviability as measured by the inability of hybrids to infect plants and produce diploid spores on S. latifolia and S. dioica, respectively. (e, f) show the evolution of F1 hybrids’ gamete sterility and the evolution of DNA content in F1 hybrids’ gametes, respectively. Continuous, broken and dotted lines stand for the ‘slowdown’, ‘linear’ and ‘snowball’ model, respectively. For each data set, the best model appears in bold.
