选择性繁殖策略（ART）提高了我们对适应性变异进化的理解;例如，在一个实施例中，他们的研究让我们明白，（例如，大而华丽）用于使用一种交配行为的策略（例如宫廷女性）通常不是最好的表型（例如小的和不显眼的）用于使用不同的交配行为的策略（例如追逐和强迫交配雌性）。然而，ART之间共享性状的遗传相关性会限制ART达到其最佳状态，导致基因座内战术冲突（IATC）。虽然进化的限制一般已经建立和研究，有一些重要的影响，由于基因座内的战术冲突的限制，艺术还没有被纳入进化生态学领域。在这里，我们描述了如何欣赏IATC，包括如何检测它和何时期待它，可以改变我们的观点在三个领域：1）适应状态的特点与艺术（例如，生长率，行为可塑性）; 2）由于种群间的生态变化而导致的选择如何产生ARTS之间的分歧模式; 3）和多态性的进化稳定性（例如IATC如何解释一种ART的丢失，以及为什么这会导致快速物种形成）。
Alternative reproductive tactics (ARTs) have improved our understanding of the evolution of adaptive variation; for instance, their study has led us to understand that the best phenotype (e.g. large and flashy) for a tactic that uses one mating behavior (e.g. court females) is often not the best phenotype (e.g. small and inconspicuous) for a tactic that uses a different mating behavior (e.g. chase and force-copulate females). However, genetic correlations of shared traits across ARTs can constrain ARTs from reaching their optimal states, resulting in intralocus tactical conflict (IATC). While constraints on evolution in general have been well-established and studied, there are some important implications of constraints due to intralocus tactical conflict on ARTs that have not been incorporated into the field of evolutionary ecology. Here we describe how an appreciation of IATC, including how to detect it and when to expect it, can change our perspectives in three areas: 1) adaptive states for traits associated with ARTs (e.g. growth rates, behavioural plasticity); 2) how selection due to ecological variation across populations can produce patterns of divergence between ARTS; 3) and the evolutionary stability of polymorphisms (e.g. how IATC can explain losses of one ART, and why this can lead to rapid speciation).
