WebThe evolutionary models of partner selection essentially view individuals as acting on the basis of evolved mechanisms, selected with a focus on maximizing ancestors' genetic fitness or increasing the likelihood of raising healthy offspring (Kenrick et al. 1993). These models contend that gender differences in preferences or selection criteria ... Fitness (often denoted or ω in population genetics models) is the quantitative representation of individual reproductive success. It is also equal to the average contribution to the gene pool of the next generation, made by the same individuals of the specified genotype or phenotype. Fitness can be defined either with respect to a genotype or to a phenotype in a given environment or ti…
