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
