Evolution of male and female genitalia following release from sexual selection.
Despite the key functions of the genitalia in sexual interactions and fertilization, the role of sexual selection and conflict in shaping genital traits remains poorly understood. Seed beetle (Callosobruchus maculatus) males possess spines on the intromittent organ, and females possess a thickened reproductive tract wall that also bears spines. We investigated the role of sexual selection and c...
متن کاملArtificial selection on male genitalia length alters female brain size.
Male harassment is a classic example of how sexual conflict over mating leads to sex-specific behavioural adaptations. Females often suffer significant costs from males attempting forced copulations, and the sexes can be in an arms race over male coercion. Yet, despite recent recognition that divergent sex-specific interests in reproduction can affect brain evolution, sexual conflict has not be...
متن کاملSexual selection and evolution of male and female choice in genetic algorithm
Variety and diversity of population are essential for convergence to global optimal in genetic algorithm. In this study, the concepts of fitness distribution, expected and cumulative fitness distribution, reproduction rate and loss of diversity are defined for a sexual selection mechanism, and their performance of this type of selection mechanism is studied theoretically. Then a genetic algorit...
متن کاملSexual Selection and the Evolution of Female Choice.
A paradox for evolutionists has been the development in one sex, usually females, of preferences for mates possessing characters that impair survival. Darwin (1871) extensively documented cases of sexual selection in animals and showed that many of the most dramatic examples are attributable to female mating preferences operating in polygynous populations. But while he was untroubled to explain...

گونه‌ی Sergentomyia (Sintonius) clydei (Sinton) برای اولین‌بار از مناطق بومی بیماری پوستی لیشمانیا در سند (Sindh)، پنجاب (Punjab)و ایالت N.W.F پاکستان گزارش می‌شود. با در نظر گرفتن گزارش‌های مربوط به ردیابی ویروس‌های عامل بیماری التهاب حاد مغز (encephalitis) توسط گونه‌های جنس Sergentomyia Franca & Theodor در مناطقی از هند و نقش احتمالی آنها در انتقال بیماری لیشمانیوز احشایی (kala-azar)، شناسایی...
