Sex differences in spiders: from phenotype to genomics.

摘要: Sexual reproduction is pervasive in animals and has led to the evolution of sexual dimorphism. In most animals, males females show marked differences primary secondary traits. The formation sex-specific organs eventually behaviors defined during development an organism. Sex determination processes have been extensively studied a few well-established model organisms. While some key molecular regulators are conserved across initiation sex is highly diverse. To reveal mechanisms underlying dimorphism identify evolutionary forces driving different sexes, must thus be detail many animal species beyond typical systems. this perspective article, we argue that spiders represent excellent group which to study mechanisms. We sexually dimorphic various morphological, behavioral, life history availability increasing number genomic transcriptomic resources functional tools provides great starting point scrutinize extensive present on mechanistic level. provide overview current knowledge propose approaches genetic underpinnings these exciting animals.
