Artificial 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 کاملEvolution 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...

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...
متن کاملEvolution of molecular phenotypes under stabilizing selection
Molecular phenotypes are important links between genomic information and organismic functions, fitness, and evolution. Complex phenotypes, which are also called quantitative traits, often depend on multiple genomic loci. Their evolution builds on genome evolution in a complicated way, which involves selection, genetic drift, mutations and recombination. Here we develop a coarse-grained evolutio...
متن کاملSurgery for Female Ambiguous Genitalia
Historically, in female pseudohermaphrodites a staged procedure with early clitoral reduction and delayed vaginoplasty was often the treatment of choice. In recent years several authors have described 1-stage genitoplasty that is performed in the first year of life. The 1stage procedure for clitoroplasty and vaginal exteriorization is preferable for an optimal functional and cosmetic result. Be...
