A sex-specific quantitative genetic theory for life history and development.
A quantitative genetic framework is developed to examine life history evolution with sex-specific differences in morphology, demographic parameters, and selection differentials occurring. Age-specific selection differentials are partitioned according to whether mediated through differential fertility, survival, or mating success, permitting the derivation of weightings according to selection mechanism as well as individual age and sex. The relationship of present to previously gained results is then examined, with applications to the evolution of bimaturism and evolutionary conservativeness of survival rate.
