We present quantitative genetic analyses of female multiple mating (FMM) in guppies to evaluate current theories proposed to explain the evolution of polyandry. Like several recent studies, notably on insects, we report limited additive genetic variance and correspondingly low heritability in FMM, thus suggesting that FMM has limited evolutionary potential. Nevertheless, we point to caveats and potential improvements in design that may yield improved estimates in FMM for quantitative genetic analyses.
