Variation in size and genomic organisation of obp gene repertoires in placental mammals. Each line represents a schematic map of the genomic organisation of obp genes (in red) and flanking genes (in blue) for the species and chromosome/scaffold indicated on the left. Species sharing the same organisation are listed on the right. Individual genes are depicted as arrows indicating their orientation on the chromosome. To visualise the shared synteny, orthologous genes are vertically aligned across species when feasible. Shades of blue of flanking genes indicate whether they typically lie distal (dark blue), proximal (medium blue) or at a large distance (light blue) from the obp locus. Genes on a different genome scaffold (in Iberian mole) are coloured ochre. Numbers above obp genes indicate their distance (in Mb) from the nearest chromosome end. Known chromosome ends are indicated by a vertical cap typically on the left of a map. Yellow windows in delineate known pseudoautosomal regions
