What is the genetic relationship between attractiveness, fighting ability and fertilization success in field crickets?

The persistence of extravagant male sexual features like horns and bright colours remains a puzzle. There are many theoretical explanations but empirical tests are still rare. This study, which uses selective breeding, will provide insight into the genetic basis of male sexual attractiveness and dominance. Although focused on an endemic field cricket the potential results have wider implications. They may be applicable to many animals of importance to the community, including livestock, domesticated animals, pests and native wildlife. All these animals are subject to selection pressure created by humans. This study will help us understand how selection on one trait (e.g. weight) may influence the evolution of another (e.g. lifespan).
