gonochorist |
0.01 sec. |
|
gonochorist fish species in which the embryonic gonad subsequently divides into ovaries or testes; may be a differentiated gonochorist, in which the differentiation is direct, or an undifferentiated gonochorists, in which there is an intermediate stage of an ovary-like gonad, a situation quite different from hermaphrodites.

| The sexuality of pectinids ranges from strictly gonochorists to functional hermaphrodites (Coe 1945, Reddiah 1962), and there are 2 types of follicular structure in hermaphroditic specimens (Coe 1945, Reddiah 1962, Gaspar-Soria et al. This is a slightly misleading interpretation in an undifferentiated gonochorist species such as the zebrafish, because males that have arrested sexual differentiation, while superficially resembling early ovary type tissue (as do both sexes at this stage), do not develop into functional females and their gonads will differentiate into testes when removed from exposure (Hill and Janz 2003). |
