The dynamics of sexual selection may prevent the simultaneous optimization of traits shared by the sexes, or of different traits within each sex. This proposal focuses on the consequences of these conflicts for phenotypic and genomic evolution. First, I will compare selection acting on a sexually dimorphic trait in males and females. Second, I will use artificial selection to create a novel sexually dimorphic trait, and track the evolutionary response. Third, I will investigate the link between two important fitness traits: body size and ageing rate. This work will enhance important on-going research in the laboratory of Robert Brooks (UNSW).

性选择的动力学可能会阻止两性共同的特征的同时优化，或者每个性别内的不同特征。这项建议的重点是这些冲突的表型和基因组进化的后果。首先，我将比较选择作用于雄性和雌性的性二型性状。第二，我将使用人工选择来创造一种新的性二型性状，并跟踪进化反应。第三，我将研究两个重要的健身特征之间的联系：体型和衰老速度。这项工作将加强罗伯特布鲁克斯（新南威尔士大学）实验室正在进行的重要研究。
