title: Unisexual fish: laboratory synthesis of a "species".
abstract: By hybridizing bisexual (gonochoristic) fishes, all-female clones have been produced that are comparable to those of a wild unisexual "species," Poeciliopsis monacha-lucida, living in northwestern Mexico. The laboratory unisexuals have consistently given birth only to female progeny for six generations.
