TLDR
It is seen that for a wide range of model parameters (deme size, distribution of male quality, local resource level), multiple mating leads to a considerable increase in the fitness.Abstract:
When there is a variation in the quality of males in a population, multiple mating can lead to an increase in the genetic fitness of a female by reducing the variance of the progeny number. The extent of selective advantage obtainable by this process is investigated for a population subdivided into structured demes. It is seen that for a wide range of model parameters (deme size, distribution of male quality, local resource level), multiple mating leads to a considerable increase in the fitness. Frequency-dependent selection or a stable coexistence between polyandry and monandry can also result when the possible costs involved in multiple mating are taken into account.read more

TL;DR: The relationship between various types of reproduction and the evolutionary process is explored, including the evolutionary development of diverse forms of sexuality, such as anisogamy, hermaphroditism, and the evolution of differences between males and females in reproductive strategy.
