To determine: Whether sexual selection increases or decreases adaptation of a population to its environment.
Introduction: Sexual selection is a selection that rests upon the fact that members of the same-sex belonging to the same species compete for mating. It is the widespread evolution and changes with the passage of time, geography of the region, number of mates, evolution of senses, and secondary sexual characteristics
To elaborate: The role of pleiotropic and good gene mechanism on female preferences and implications of these preferences on their adaptation.
Introduction: Survival of the species requires them to adapt to the environment. Natural selection is an important part of adaptation along with the game production that increases the probability of fertilization and birth. A sexual selection is, however, completely different process in which secondary sexual characters evolve in a different way than the above process. The biggest mistake that can be made by a female is to mate with different species and thus produce infertile or non-viable offspring. Hence, several factors help in affecting female preferences toward the selection of the males of the same sex.
