Intergenic distances between gene-pairs mapping to orthologous positions in human and cow. Promoters in the human dataset were limited to an intergenic distance of < 1,000 bp, whereas the intergenic distances at the orthologous bovine promoters were unlimited. Orthologous gene pairs with the same relative distance in each species fall alongside the red diagonal line (i.e., where X = Y).
