The zebrafish phenotype ontology contains data from ZFIN about zebrafish genotype - phenotype associations primarily obtained by ZFIN curators from the literature. Phenotype terms are described as an anatomy term (what is affected by the gene knockout) and a quality term (how is the anatomy structure affected).
Statistics can now be found in the footers of each table in the GREAT web output.
All data for this ontology was downloaded on Jan 2, 2011 from ZFIN.
GREAT v1.8 Zebrafish Phenotype statistics are available here.
