The flexibility in the sexual expression of a species and the evolution of sequential hermaphroditism in previously gonochoristic populations can be simulated by setting the initial frequencies of each sex and the predominance of lifetime males and females, with which can occurs four flexibility strategies (Warner, 1975): (1) change from a male to female (protandry); (2) change from female to male (protogyny); (3) change from female to hermaphrodite (protogynous hermaphroditism); (4) change from male to hermaphrodite (protandrous hermaphroditism).

However, other researchers have suggested background levels of hermaphroditism in any normally gonochoristic fish species, like largemouth bass, should be very low (Blazer et al, 2007, Blazer et al, 2012).

Crustaceans exhibit a variety of sexual systems, ranging from gonochoristic (separate sexes) to a wide range of sequential, simultaneous, and mixed hermaphroditic systems (Charniaux-Cotton and Payen, 1985; Bauer, 2000; Avise, 2011; Weeks et al., 2014).
