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.
