Sexual selection refers to selection on individuals of the non-limiting sex (usually males) caused by differential access to the limiting sex (usually females). Following Julian Huxley, most people divide sexual selection into two components: intrasexual selection and intersexual selection. Intrasexual selection refers to selection caused by male-male competition, while intersexual selection refers to selection caused by female preferences. This chapter focuses on the evolution of preferences for seemingly maladaptive, exaggerated male traits. Much of the literature divides explanations for the evolution of female preferences into three distinct categories: Fisherian runaway models, good-genes models, and sensory bias models. This chapter also presents a new set of tools to model the evolution of female preferences. It begins by considering the quantitative genetic models and then looks at Russ Lande's model of the runaway process as well as its descendants. The chapter also examines a game-theoretic model by Hanna Kokko, John McNamara, and their coworkers that provides a very clear understanding of the relationship between Fisherian models and so-called good-genes models.Less

At each new generation, sexual reproduction creates new combinations of nuclear and mitochondrial genes, and the potential arises for mitonuclear incompatibilities and reduced fitness. Sexual selection plays a key role in maintaining mitonuclear coadaptation across generations because it enables pre-zygotic sorting for coadapted mitonuclear genotypes. In this chapter, I present data that individuals engaged in mate choice select partners with correct species-typical mitochondrial and nuclear genotypes as well as individuals with highly functional cellular respiration. The implication is that mate choice for compatible nuclear and mitochondrial genes can play a significant role in generating the patterns of ornamentation and preferences observed in animals.Less
