The four human and one Drosophila Hox complexes are homologues. The colour coding in Panels A and B shows the correspondence between the genomic order of Hox genes in the Hox complexes (A) and their spatial sequence of expression and action zones along the main body axis in Drosophila and human (B) [57].
