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

男性的性特征，如角和鲜艳的颜色，是否会持续存在，仍然是一个谜。理论上有很多解释，但实证检验仍然很少。这项研究采用选择性育种，将深入了解男性性吸引力和优势的遗传基础。虽然集中在一个地方性的领域板球的潜在结果有更广泛的影响。它们可能适用于对社区重要的许多动物，包括牲畜、家养动物、害虫和本地野生动物。所有这些动物都受到人类创造的选择压力。这项研究将帮助我们了解一个性状（例如体重）的选择如何影响另一个性状（例如寿命）的进化。

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).
