Unisexual fish: laboratory synthesis of a "species"

R J Schultz. Science. .

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.
