The mouse Obox loci and associated genes. There are 36 mouse Obox homeobox loci, comprising 6 intron-containing genes (orange arrows) and 28 intronless loci (unfilled arrows) on chromosome 7, plus intronless probable pseudogenes on chromosome 17. Four other homeobox genes, not clearly part of the Obox family, are linked to the large Obox cluster: Crxos1, Gm5585 and Gm7235 and Crx (red arrows).
