Regions of conserved synteny among vertebrate genomes. Only some genes, whose position within a syntenic group is informative, are shown. Thus a small number of intervening genes lie between some genes that are depicted as directly flanking for simplicity. Larger intergenic distances are depicted by parallel diagonal lines. Key genes mentioned in the text are highlighted in colour.
