Fig. 2.

Synteny of Hox genes between Acanthopelura granulata and other taxa. The presence of a gene is indicated by a box of the corresponding color. Continuous black lines indicate that the Hox genes in this species were located on a contiguous genomic scaffold. Broken black lines indicate that gene(s) are located on multiple genomic scaffolds. A double slash indicates genes are located on a single contiguous scaffold but separated by greater distances than those in most other taxa.
