Genomic organization of the Hox gene cluster in a sampling of Hexapod species. Hexapod species phylogeny is after [25]. Scaffold-level sequences are annotated with a (*) after the species; all others are chromosome level. Ellipses within the sequences denote excluded genomic sequence, with the values above them denoting excluded sequence size. Hox genes are annotated as colored boxes: lab (green), pb (orange), zen (dark grey), Dfd (sky blue), Scr (red), ftz (light grey), Antp (purple), Ubx (blue), abd-A (yellow), Abd-B (pink). Note that the E. danica sequence is a concatenation of two scaffolds, the consensus overlap of which is denoted by a white box. Black arrowheads above Hox genes show sequences with opposite gene orientation. Values to the right of each sequence represent the size of the sequence shown, including ellipses, and its percentage in regard to the sequence’s full size. Accession values for the scaffolds and chromosomes used are provided in Additional File 1: Table S1
