The Weird Sex Lives of Bluegills

Bluegill fish exhibit unique mating strategies involving three types of males: brawny males, female mimics, and sneaker males. Brawny males build nests and attract females, while female mimics and sneaker males use deception to fertilize eggs. This balance of strategies ensures genetic diversity and survival, as deception cannot dominate due to the need for brawny males to maintain the ecosystem.

What is the significance of having normal males in the bluegill population?

Explain how the success of deception in mating strategies is affected by its commonality.
