Hox gene
…have a single Hox cluster with 15 genes, known as AmphiHox1 to AmphiHox15. Six Hox genes are dispersed in the genome of Caenorhabditis elegans, a roundworm. Hydra and Nematostella vectensis, both in the phylum Cnidaria, have a few Hox/ParaHox-like homeobox genes. Hox gene expression has also been studied…
