| Phenotype | Exposure | Definition |
|---|---|---|
| Multigenerational | Direct | Coincident direct exposure of multiple generations to an environmental factor or toxicant promoting a toxicology in the multiple generations exposed |
| Transgenerational | None, except the initial (ancestral) generation |
