Abstract

The evolution of parthenogenesis is investigated through the analysis of quantitative models of genetic change. I propose a measure of the "cost of meiosis" in terms of average effects of allelic substitution. Under this definition, the cost of outcrossing depends upon relatedness between the parent and its sexually- and asexually-derived offspring as well as the reproductive value of each offspring type. An explicit genetic model involving sibmating shows that the cost of outcrossing depends in a complex way on the system of mating.
