Population Structure, Frequency-Dependent Selection, and the Maintenance of Sexual Reproduction
Preview not available

Abstract

A model of frequency-dependent selection in a stable and homogeneous environment predicts that a gene for sexuality will spread in a predominantly asexual population, so long as rare genotypes are sufficiently favored by selection and offspring dispersal is sufficiently limited. We discuss evidence that these conditions are realistic for many organisms, and conclude that frequency-dependent selection and limited dispersal could contribute substantially to the widespread occurrence of sexuality, especially among low-fecundity organisms living under apparently stable conditions.
