Homeobox-containing genes are frequently duplicated in P. tepidariorum and C. sculpturatus. Many duplicated homeobox gene families (overlap of red and green shading) are shared between P. tepidariorum (indicated in green) and C. sculpturatus (indicated in red). Single copy families are the next largest group shared, then families that are single copy in one species but duplicated in the other. There are also a few families that were only found in one species
