Polymorphisms occur in nature. Aside from the famous morphological polymorphism in the peppered moth Biston bitularia (Cook et al. 1999) polymorphisms are also recognisable in animal behaviour. Animal personalities are consistent individual differences in suites of correlated behaviours (Réale et al. 2007). Correlated behaviours can vary within and between individuals of a species, leading to a broad spectrum of variable animal personalities that are known to have a genetic background. Animal personality can be either flexible or non-flexible, both types are present in nature. Differential selective advantages and frequency dependent selection are thought to be responsible for the fact that animal personalities can persist in nature. However, recent studies have contradicting results which makes it hard to draw conclusions about frequency dependence being a mechanism for maintaining variation in personalities. How personalities persist in nature therefore remains a question to be answered.
