I have found two TO examples of ratio-type traits that also have logical definitions: * [TO:0000278 root to shoot ratio](https://www.ebi.ac.uk/ols4/ontologies/to/classes/http%253A%252F%252Fpurl.obolibrary.org%252Fobo%252FTO_0000278) * [TO:0000525 sodium to potassium content ratio](https://www.ebi.ac.uk/ols4/ontologies/to/classes/http%253A%252F%252Fpurl.obolibrary.org%252Fobo%252FTO_0000525) The two classes...

There are two term requests in RO that look relevant to the modelling of qualities emerging from two qualities that are in a ratio/proportion relationship: * Adding the now deprecated...

* I think we need a new pattern template for the traits in the table. I suggest: ['process quality'](https://www.ebi.ac.uk/ols/ontologies/pato/terms?iri=http%3A%2F%2Fpurl.obolibrary.org%2Fobo%2FPATO_0001236) and ('[characteristic of](https://www.ebi.ac.uk/ols/ontologies/ro/properties?iri=http%3A%2F%2Fpurl.obolibrary.org%2Fobo%2FRO_0000052)' some (['gene expression'](https://www.ebi.ac.uk/ols/ontologies/go/terms?iri=http%3A%2F%2Fpurl.obolibrary.org%2Fobo%2FGO_0010467) [has participant](https://www.ebi.ac.uk/ols/ontologies/ro/properties?iri=http%3A%2F%2Fpurl.obolibrary.org%2Fobo%2FRO_0000057&lang=en&viewMode=All&siblings=false) some %s)) ,...
