Evolution has a tendency to encourage the advancement of a single favorable female and male phenotype for each species (Brazill-Boast, Griffith, & Pryke 2013). The incidence of more than one discrete, heritably controlled colour form in a single population is referred to as genetic colour polymorphism (Gilby, Pryke, & Griffith 2009). This phenomenon occurs in birds, fish, insects, frogs, and lizards (Dijkstra et al. 2009). Organisms displaying these variations are termed as morphs. Apart from appearance, discrete morphs can also show variation in features such as behaviour and bodily processes. According to Gilby, Pryke and Griffith, the examination of these species reveals detailed information on a number of fundamental ecological and evolutionary procedures (2009). A complete understanding of these processes plays a significant role in the comprehension of speciation and diversity. For instance, it is assumed that equilibrium between diverse genetic morphs is displayed by the subsistence of a stable genetic polymorphism in a distinct interbreeding populace. This presents an evolutionary challenge that can only be resolved by a study that combines ecological, behavioural and genetic processes (Gilby, Pryke, & Griffith 2009).
