Putting sexual selection in a life-history context: What is meant by genetic quality?

性信号理论的发展很大程度上没有参考生活史理论和数量遗传学。我们将测试最近的理论，该理论表明，信号的成本最好以未来生存和繁殖的单位来衡量。在对蟋蟀Teleogryllus commodus进行的一系列野外和实验室实验中，我们将检验这样一种观点，即性选择的好基因模型所指的“雄性遗传质量”是指获得资源的一般能力，而不是资源如何在健康成分之间分配。

Theories of sexual signalling have been developed largely without reference to life-history theory and quantitative genetics. We will test recent theory that shows the costs of signals are best measured in units of future survival and reproduction. In a series of field and laboratory experiments on the cricket Teleogryllus commodus, we will test the idea that the "male genetic quality" referred to by good-genes models of sexual selection is quality in the general ability to acquire resources, rather than in how resources are allocated among fitness components.
