Every gene, marker, clone or other Genomic Segment that appears on any primary map of a chromosome appears on the comprehensive map as well. The comprehensive maps thus provide a synthesis of all the mapping data for a chromosome.
Displays based on comprehensive maps provide users with an integrated view of the genome.
This is often more convenient than a display of aligned primary maps, since it allows map elements to be grouped by type. Note that by convention a chromosome ideogram is used as the backbone of these displays, but the comprehensive maps are not cytogenetic maps . The band sizes on these ideograms will differ from standard ideograms, since they reflect the positions of the bands in the comprehensive map coordinates, which are based on a selected high-resolution primary map. For best viewing, use Netscape 3.0 or higher Please read the GDB Termination Announcement.
