The presence of Hox genes is a defining characteristic of animals. Hox genes play a critical role in the development of the body plan, including the segmentation of the body and the regional specialization of structures such as limbs and organs. While some other organisms such as fungi and plants may have Hox-like genes, the presence of true Hox genes is limited to the animal kingdom.
