The number of classes in each pre-composed phenotype ontology is shown, together with the size of the subset of these classes that have been mapped to EQ descriptions. The EQ descriptions can be broken down further into subsets, depending on which ontologies are used. Note the subset numbers are not mutually exclusive, as there are scenarios where an EQ descriptions references multiple ontologies, so the numbers are not additive. PO, Plant Ontology (anatomical structure); WBbt, Worm anatomy ontology.
