zebrafish phenotype ZFIN do not annotate with a pre-composed phenotype ontology - all annotations compose phenotypes on-the-fly using a combination of PATO, ZFA, GO and other ontologies. So while there is no manually curated zebrafish phenotype ontology, the Upheno pipeline generates one automatically here: http://purl.obolibrary.org/obo/upheno/zp.owl This ontology does not have a root 'phenotype' class, however, and so we generate our own in GENO as a stub placeholder for import of needed zebrafish phenotype classes.
