overscience_mes — 05.03.2010 Females of most animal species are polyandrous, with individual females usually mating with more than one male . However, the ubiquity of polyandry remains enigmatic because of the potentially high costs to females of multiple mating . Current theory to account for the high prevalence of polyandry largely focuses on its benefits to individual females

Thus, the frequency of female multiple mating in nature may be associated not only with individual benefits to females of this behavior but also with increased persistence over time of polyandrous species and populations. Furthermore, we show that female remating behavior can determine the frequency of sex-ratio distorters in populations. This may also be true for many other selfish genetic elements in natural populations.

Жаль, что последний автор женщина... А то бы можно было бы говорить, что так даже мужчины думают :)

Любите нас, любите - это на пользу популяции :)
