I'm missing what you're doing here that foreign keys don't cover.
Could you send along your DDL?
Just

between variant and phenotype?
Exactly. You might have one group say that allele X causes some trait,
whereas

No DDL yet... I'm just in the thinking stages. FKs technically would do
it, but would become unwieldy. The intention was to have subclasses of

I'm considering a project to model genomic variants and their associated
phenotypes. (Phenotype is a description of the observable trait, such as
disease or hair
