Abstract

Males and females experience divergent selection on many shared traits, which can lead to 'sexual antagonism' - opposing fitness effects of genetic variants in each sex. A new study in the fly Drosophila serrata links sexually antagonistic selection on cuticular hydrocarbons to a single major-effect gene.

摘要

雌雄两性在许多共享特征上经历不同的选择，这可能导致“性拮抗”——遗传变异在每个性别中的适应性效应相反。在果蝇 serrata 中的一项新研究将表皮碳氢化合物上的性拮抗选择与一个主要效应基因联系起来。
