Definition
The degree to which sexual selection pressures female members of a species. Female reproductive variance is tied to the fertility of the individual and less to their ability to mate and reproduce. Hence, female reproductive variance is quite low relative to male reproductive variance.
Introduction
Research has found a pattern of reproductive variance for many species in which females have far less variability in their reproductive output than males. Three factors contribute to the pattern of mating behaviors that are typical for females: most females successfully reproduce, the amount of copulations shows a weak relationship with the number of offspring for females, and for many species, females have a greater minimum obligate investment to produce viable offspring.

Angus Bateman is among the first to formally study reproductive variance. In 1948, Bateman...
