The past two decades have seen extensive growth of sexual selection research. Theoretical and empirical work has clarified many components of pre- and postcopulatory sexual selection, such as aggressive competition, mate choice, sperm utilization and sexual conflict. Genetic mechanisms of mate choice evolution have been less amenable to empirical testing, but molecular genetic analyses can now be used for incisive experimentation. Here, we highlight some of the currently debated areas in pre- and postcopulatory sexual selection. We identify where new techniques can help estimate the relative roles of the various selection mechanisms that might work together in the evolution of mating preferences and attractive traits, and in sperm-egg interactions.
在过去的二十年里，性选择研究得到了广泛的发展。理论和实证研究已经阐明了交配前和交配后性选择的许多组成部分，如激烈竞争、配偶选择、精子利用和性冲突。配偶选择进化的遗传机制较难进行实证检验，但现在分子遗传学分析可用于深入实验。在这里，我们重点介绍一些目前在交配前和交配后性选择中存在争议的领域。我们确定了新技术可以在哪些方面帮助估计各种选择机制的相对作用，这些机制可能共同作用于交配偏好和吸引性状的进化，以及精卵相互作用。
