Supergenes are not necessary to explain the maintenance of complex alternative phenotypes.

Abstract excerpt

Evolutionary biology aims to explain the diversity seen in nature. Evolutionary theory provides frameworks to understand how simple polymorphisms or continuous variation are maintained, but phenotypes inherited as discrete suites of quantitative traits are difficult to fit into this framework. Supergenes have been proposed as a solution to this problem-if causal genes are co-located, they can be inherited as if a...
