The query results provide a tablular display of homology classes. A class is a set of homologous markers. For each homolog in a class, the record shows some or all information in the following table, depending on information available. Symbol Symbol for an homologous marker. The chromosome the marker is assigned to, and, enclosed in parentheses, the cM position or cytogenetic band .
Location information varies depending on information available.
The database accession IDs assigned to the marker. Accession IDs come from the database where the marker record is stored. Currently, MGI stores homology information from GDB , SheepBase, RatMap, BovMap, PigBase, HorseBase and Ark-Cat. Criteria MGD homology information includes criteria for homology assertions. In addition, each criterion is associated with one or more references.
