TRANSITIONS. “When separate sexes are favored, the transition can occur via several evolutionary pathways. Separate sexes may evolve from hermaphrodites either by gradual increases in sex-specific investment or rapidly by the appearance of male- or female-sterility mutations. The latter occurs regularly in plants, often generating mixed sexual systems, such as gynodioecy (mixtures of females and hermaphrodites) and androdioecy (mixtures of males and hermaphrodites).”
