Any feasible and individually rational payoff of the game may...

Frequency-dependent selection may favor the evolution of mixed reproductive strategies, resulting in polymorphic life-histories within a population. Here I explore the theoretical and ecological possibilities for evolution of mixed reproductive strategies in two minimal age-structured...
