Abstract

A model of the effects of random variations in environment upon reproductive fitness of sexual and asexual members of a population is analyzed, using individual selection arguments. Conditions are found under which sexuality does result in a net selective advantage, with the conditions per locus becoming markedly less severe as the number of loci considered increases.
