In the bighorn sheep population of North America, what would happen if all of the large-bodied, large-horned males were hunted, leaving only small-bodied, small-horned sheep?  a)Males could no longer protect females from predators, so eventually all of the sheep would be eaten by predators. b)There would be no phenotypic variation in the population of sheep, and natural selection could not lead to males with larger horns in the future. C)The size of horns would no longer be a heritable traits, and would males would not pass this trait to their offspring. d)Males would begin to use their horns for other behaviors, such as hunting prey or being better competitors.

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.
