ele frequencies among the zygotes may be quite different than they are in the gene pool. e effects of natural selection are more pronounced in small populations. anges in allele frequencies over many generations are inevitable with sexual reproduction. les combine more randomly with a small number of zygotes. e effects of sampling error are more pronounced with smaller samples.

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.
