- Mate value is derived from Charles Darwin's theory of evolution and sexual selection, as well as the social exchange theory of relationships. Mate value is defined as the sum of traits that are perceived as desirable, representing genetic quality and/or fitness (biology), an indication of a potential mate's reproductive success. Based on mate desirability and mate preference, mate value underpins mate selection and the formation of romantic relationships. Mate value can predict availability of mates, for example, a higher mate value means one is desirable to more individuals and so can afford to be more choosy in mate selection. Thus, one's own mate value can influence trait and mate preferences, it has been shown that an individual will show preference for another who has a similar mate value, to avoid rejection. Specifically, one could infer that one's own mate value has a direct impact upon partner choice through the biological market theory. Here, it is believed that 'high-market' (more attractive individuals), are able to translate mate preference into actual choice, primarily due to the fact they have more to offer, such as positive health markers, consequently affecting reproductive success Ultimately, mate value has been suggested as a 'determining factor in mate choice', consequently influencing the reproductive success of an individual. Factors such as attractiveness can influence perceived mate value. It has been suggested that preferences dictate an individual's mate value, leading to the prioritising of certain characteristics by some and not others. This results in potential mates having various mate values dependent on the mate-seekers's preferences. For example, a woman looking for a long-term partner may value a mate of high status and great access to resources, as well as genetic benefits to provide for and increase the reproductive success of offspring. Alternatively, a woman looking for a short-term mate may show preference for non-genetic benefits such as food, with little regard to the attractiveness or status of the man. Further influences of mate value may include cultural effects, sex differences and evolutionary impacts. (en)
