Synteny. The presence of two or more genetic loci on the same chromosome. Extensions of this original definition refer to the similarity in content and organization between chromosomes, of different species for example.
(Syntenic regions are chromosomal regions in two different species that contain the same linear order of genes.) With mapping of the human and mouse genomes now complete, researchers can identify syntenic regions in mouse and human chromosomes with great precision.
