robust species definitions are a necessity if we build species lists, analyze their distribution, or consider the evolution of mimicry [22]. As we learned earlier, polymorphism expressed as sexual dimorphism is very common in nature. Finally, reproducibility has been a concern with certain anonymous marker types, particularly randomly amplified polymorphic DNA (RAPD) and, to a lesser extent, AFLPs (Jones et al., 1997). balanced polymorphism an equilibrium mixture of homozygotes and heterozygotes maintained by natural selection against both homozygotes.

Polymorphic species exhibit heritable discrete or qualitative phenotypic variants within the same population, with little variance determined by the environment (Ford 1945; Huxley 1955).Polymorphisms are often correlated with a number of characteristics and may form resource polymorphisms or behavioural syndromes (Smith & Skulason 1996; Dochtermann & Dingemanse 2013).

robust species definitions are a necessity if we build species lists, analyze their distribution, or consider the evolution of mimicry [22]. As we learned earlier, polymorphism expressed as sexual dimorphism is very common in nature. Finally, reproducibility has been a concern with certain anonymous marker types, particularly randomly amplified polymorphic DNA (RAPD) and, to a lesser extent, AFLPs (Jones et al., 1997). balanced polymorphism an equilibrium mixture of homozygotes and heterozygotes maintained by natural selection against both homozygotes.
