Intra-genomic conflict and the evolution of sexually selected traits

性选择的动态可能会阻碍两性共有的特征或每个性别内的不同特征的同时优化。这项建议侧重于这些冲突对表型和基因组进化的影响。首先，我将比较选择作用于男性和女性的性二态特征。其次，我将使用人工选择来创造一个新奇的性二型特征，并跟踪进化反应。第三，我将调查两个重要的健康特征之间的联系：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。

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).
