In between breeding systems: neither dioecy nor androdioecy explains sexual polymorphism in functionally dioecious worms.

Integrative and comparative biology - 1 Oct 2013

Lorenzi M Cristina, Sella Gabriella

Abstract excerpt

Related species share genetic and developmental backgrounds. Therefore, separate-sex species that share recent common ancestors with hermaphroditic species may have hidden genetic variation for sex determination that causes some level of lability of expression of gender. Worms of the polychaete species Ophryotrocha labronica have separate, dimorphic sexes and their ancestor was hermaphroditic. Ophryotrocha...
