Hybridization is a common phenomenon in both plant and animal kingdoms. Recent data suggest that hybridization is a creative force forming novel genotypes and allowing rapid adaptation to new environments. Assessing hybrid fitness relative to that of the parental taxa is crucial for understanding the widespread nature of hybridization. For example, differences in hybrid and parental infection levels could affect the relative success of hybrids in natural populations. In hybrid and other systems, both host susceptibility and parasite infectivity commonly have a genetic basis. However, these traits are often sensitive to environmental variation, resulting in genotype-by-environment interactions, both of which have been often neglected in theoretical models and empirical studies.

杂交是植物界和动物界的普遍现象。最近的数据表明，杂交是一种创造性的力量，可以形成新的基因类型，并允许快速适应新的环境。评估杂交适合度相对于亲本分类群的适合度对于理解杂交的普遍性质至关重要。例如，杂交和亲本感染水平的差异可能会影响杂交后代在自然种群中的相对成功。在杂交种和其他系统中，寄主敏感性和寄生虫传染性通常都有遗传基础。然而，这些性状往往对环境变化很敏感，导致了基因与环境的互作，这两个因素在理论模型和实证研究中往往被忽视。
