Male Bluegill Sunfish (Lepomis Macrochirus) May Be Either a Parental

Male bluegill sunfish (Lepomis macrochirus) may be either a parental male or a cuckholder. Cuckholders, in turn, may be either sneakers or female mimics. Each of these three forms represents an alternative reproductive strategy. The three strategies are

A) determined by the relative abundance of food and nesting resources during that breeding season.
B) displayed as a portion of a discrete life history polymorphism and are, thus, determined by the individual's age and body size.
C) divided approximately evenly across the males in the population, with the form for a particular male being determined at hatching, pretty much randomly.
D) influenced by the number of breeding females available within that population.
