From: Evolutionary plasticity in nematode Hox gene complements and genomic loci arrangement

Hox gene clusters for eight selected species of Nematoda and for all three studied species of Nematomorpha showing synteny relationships of Hox cluster loci. Identified Hox genes and their respective transcriptional orientations are indicated by arrow boxes which are coloured by orthology group. Dashed horizontal lines indicate cluster breakage in scaffolded genomes. Lineage-specific duplications include paralog groups Hox6-8 and Hox9-13. Cross indicate a break that resulted from gaps in un-scaffolded draft genome. The cladogram on the left summarises the relationships between species.
