Table pub.mgd.mgi_organism_mgitype
A record in this table represents the relationship between an Organism and a MGI Type; what Organisms are valid for a given MGI Type. An Organism can be associated with one or more MGI Types. This enables us to generate a list of Organisms by MGI Type. Examples are Orthology, Molecular Segment , GXD Antigen, GXD Antibody, Sequence, Marker.
