互利共生的悖论通常被描述为种间合作的持续存在，尽管作弊具有潜在的优势。因此，互利共生研究往往侧重于防止低质量合作伙伴入侵的稳定机制。这些机制本身无法解释自然界中观察到的伴侣质量变异的持续存在，这使得我们对互利共生如何演变的理解存在很大差距。研究伴侣质量变异对于应用遗传显性模型来预测自然种群的进化是必要的，这是理解互利共生的起源及其持续动态的必要步骤。进化遗传学方法专注于自然发生的互利共生变异，有可能综合目前互利共生进化和共同进化遗传学互不相关的领域。我们概述了维持互利共生遗传变异的解释，并提出了解决这些问题所需的方法。
The paradox of mutualism is typically framed as the persistence of interspecific cooperation, despite the potential advantages of cheating. Thus, mutualism research has tended to focus on stabilizing mechanisms that prevent the invasion of low-quality partners. These mechanisms alone cannot explain the persistence of variation for partner quality observed in nature, leaving a large gap in our understanding of how mutualisms evolve. Studying partner quality variation is necessary for applying genetically explicit models to predict evolution in natural populations, a necessary step for understanding the origins of mutualisms as well as their ongoing dynamics. An evolutionary genetic approach, which is focused on naturally occurring mutualist variation, can potentially synthesize the currently disconnected fields of mutualism evolution and coevolutionary genetics. We outline explanations for the maintenance of genetic variation for mutualism and suggest approaches necessary to address them.
