Selection sometimes favors the extreme phenotypes in a population. This would cause hybrid individuals to experience decreased fitness and likely lead to sexual selection within groups of similar phenotypes. Eventually this sort of evolutionary pressure may lead to Genetic Drift O Allopatric Speciation Sympatric Speciation O Stabilizing Selection

Sexual Motivation

Sexual motivation refers to a person's overall desire for sexual activity. It is an unusual motivation. Generally, among lower animals, the term 'drive' is commonly referred to as sexual motivation. It means a certain internal force drags the animal to be involved in reproductive behavior. On the contrary, humans are not simply driven by any internal force; rather, the sexual motivation in humans is due to several factors such as biological (hormones, genes), environmental (familial upbringing, chemical exposure) and physiological factors (culture, desire) which further determine engagement in sexual activities.
