Abstract
IN ecological studies of the marine supralittoral genus Orchestia (Crustacea, Amphipoda) many populations have been found that have biased sex ratios (ref. 1 and unpublished results of D. J. W.). Thelygeny has also been found in some of the terrestrial species of Orchestia2, and in the sublittoral, species, Orchestia gammarella (Pallas), both amphogenous and thelygenous populations have been found3. I have investigated the possibility that biased sex ratio populations have an adaptive advantage in altering reproductive potential and the phylogenetic mechanism controlling its origin.
