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).
This natural estrogen has been frequently used in gonochoristic species; however, there are few studies on induced feminization in hermaphroditic fishes.
canaliculatus possessing respective sex organs and secondary sex characteristics throughout life stages of growth and development (i.e., gonochoristic).
Demographic plasticity for age and growth and in reproductive parameters pertaining to maturity, sex change, or both (Adams et al., 2000; Gust, 2004; Munday et al., 2006; Mariani et al., 2013) has been documented in both gonochoristic (Choat and Robertson, 2002; Robertson et al., 2005) and hermaphroditic (Gust et al., 2002; Donovan et al., 2012) species of coral reef fish.
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).
It is a solitary, gonochoristic species with no evidence of sexual reversals being observed.
Breadth and overlap of the diet between syntopic populations of parthenogenetic Aspidoscelis tesselata C and gonochoristic Aspidoscelis sexlineata (Squamata: Teiidae) in southeastern Colorado.
It is to mention here that the letrozole exposed fishes retained the sex reversed masculinity until six months of observation even after withdrawal of the treatment suggesting that gonochoristic fish particularly common carp and tilapia maintain their sexual plasticity until adulthood [39].
