Expert Solution

Sexual selection significantly impacts evolution because of the magnification of individuals' choices, shaping their genetic variations. Males’ relative fitness models influence the outcomes whereby rapid adaptive changes due to the mutational benefits require significant fitness levels than average. Females can choose their preferred male partners regardless of their basis so long as there are no significant genetic variations among the male populations (Dugatkin, 2021). Asexual females have a tremendous potential of reproducing than sexual females because they require to mate with males to produce equal female and male populations.
