A quantitative approach to mating system analysis emphasizes the measurement of sex differences in the variance in relative fitness, as well as genetic correlations that may arise among breeding pairs. Such information allows mating systems to be classified using data commonly available from ecological, life history, and behavioral analyses. This empirical framework for the study of mating systems stresses quantification of the evolutionary forces responsible for male–female differences, an approach that is easier to test and provides less ambiguous answers than current frameworks emphasizing evolutionary outcomes predicted by optimality theory or sex differences in parental investment.
