VERTEBRATE TRAIT ONTOLOGY - ANNOTATIONS

The Vertebrate Trait Ontology (VT) is being developed as a collaborative effort between the Rat Genome Database at the Medical College of Wisconsin (RGD, http://rgd.mcw.edu), Mouse Genome Informatics at the Jackson Laboratory (http://www.informatics.jax.org/) and the Animal QTL database at Iowa State University (http://www.animalgenome.org/cgi-bin/QTLdb/index). For more information about this vocabulary, or to request additions or changes, please contact us (http://rgd.mcw.edu/contact/index.shtml).
