当雄性生殖成功取决于雄性之间的竞争和侵略时，处于竞争劣势的个体有时会采取完全不同的生殖行为。当这种替代性的生殖模式是机会主义的时候，比如当一个被击败的领土雄性采取寄生角色时，或者作为发展序列的一部分，比如当年轻的雄性是卫星时，它们可以被认为是一个单一的一生生殖策略的一部分。相反，如果有其他选择，但个人一生中只有一种生殖选择，则可以考虑遗传多态性的可能性。这种遗传介导的替代性生殖策略已被假设1，但个体发育假设替代性生殖策略是很少知道2。这封信描述了两种繁殖模式，蓝鳃太阳鱼（Lepomis macrochirus），筑巢男性战略和女性模仿战略，并表明，一个单独的男性不实行这两种繁殖策略。
When male reproductive success depends on male–male competition and aggression, individuals which are at a competitive disadvantage sometimes adopt an entirely different constellation of reproductive behaviours. When such alternative reproductive patterns are practised opportunistically, as when a defeated territorial male adopts a parasitic role, or as part of a developmental sequence, as when younger males are satellites, they can be considered to be part of a single lifetime reproductive strategy. In contrast, when alternatives are available but individuals practise only a single reproductive option throughout their lifetime, the possibility of a genetic polymorphism can be considered. Such genetically mediated alternative reproductive strategies have been hypothesised1, but the ontogeny of supposed alternative reproductive strategies is seldom known2. This letter describes two reproductive patterns in bluegill sunfish (Lepomis macrochirus), a nesting male strategy and a female mimic strategy, and demonstrates that an individual male does not practise both reproductive strategies.
