很少有实验表明，性选择过程与后代的健康益处之间存在遗传相关性，无论是通过雌性选择还是雄性竞争。那些研究雌性选择与后代健康之间关系的人关注的是幼年健康成分，而不是生命周期后期的健康。此外，这些研究中有许多没有控制可能的母体效应。为了检验性选择和成虫适合度之间的关系，我们在果蝇中进行了一个人工选择实验。我们创造了两种治疗方法，在性选择的机会水平上有所不同。女性选择和男性竞争的机会增加与成年生存率的增加以及男性和女性体型的增加在遗传上相关。与以前的单代研究相反，我们没有发现幼虫竞争能力的增加。这项研究表明，配偶的选择和/或男性-男性的竞争与后代的至少一个成年健身组件的增加。
Few experiments have demonstrated a genetic correlation between the process of sexual selection and fitness benefits in offspring, either through female choice or male competition. Those that have looked at the relationship between female choice and offspring fitness have focused on juvenile fitness components, rather than fitness at later stages in the life cycle. In addition, many of these studies have not controlled for possible maternal effects. To test for a relationship between sexual selection and adult fitness, we carried out an artificial selection experiment in the fruit fly,Drosophila melanogaster. We created two treatments that varied in the level of opportunity for sexual selection. Increased opportunity for female choice and male competition was genetically correlated with an increase in adult survivorship, as well as an increase in male and female body size. Contrary to previous, single-generation studies, we did not find an increase in larval competitive ability. This study demonstrates that mate choice and/or male–male competition are correlated with an increase in at least one adult fitness component of offspring.
