We often think that discrete polymorphisms are relatively rare. However, most species that we study create two rather different phenotypes from almost (or sometimes completely) identical genotypes: males and females. This polymorphism often creates more “wasteful” traits in males than females, and is responsible for the famour two-fold cost of sex. The cost is not always twofold, however: it depends on how males behave. I will draw examples from various taxa (from polymorphic birds to aquatic invertebrates) to help answer questions such as: does it matter how males behave? What determines how they behave? and why does this polymorphism exist in the first place?
