The transcriptomic basis of tissue- and nutrition-dependent sexual dimorphism in the beetle Onthophagus taurus.

ABSTRACT: Sexual dimorphism accounts for a large fraction of intraspecific diversity. However, not all traits are equally sexually dimorphic; instead, individuals are mosaics of tissues that vary in their ability to exhibit dimorphism. Furthermore, the degree of a trait's sexual dimorphism is frequently environment-dependent, with elaborate sexual dimorphism commonly being restricted to high nutritional conditions. Understanding the developmental basis and evolution of condition-dependent sexual dimorphism can be critically informed by determining - across tissues and nutritional conditions - what sex-biased genes are deployed and how they interact and translate into functional processes. Indeed, key theories concerning the evolution of condition-dependent sexually dimorphic traits rest on assumptio
