The sexually dimorphic stag beetle.
The evolution and development of sex-specific traits in animals has long fascinated biologists. How have these traits developed and evolved? What are the genetic mechanisms underlying the diversity of sexually selected, sex-specific traits in animals? In this issue, Gotoh and colleagues present results from a study linking the sex-determination pathway with the regulation of condition-dependent mandible growth in the stag beetle Cyclommatus metallifer. Their study focuses on the conserved sex-determination gene doublesex (dsx) and its interaction with juvenile hormone, which together regulate condition-sensitive growth of sex-specific traits in the sexually dimorphic stag beetle.
