WebFeb 28, 2024 · The animal genes containing homeobox sequences are specifically referred to as Hox genes. This family of genes is responsible for determining the general body plan, such as the number of body segments of an animal, the number and placement of appendages, and animal head-tail directionality. There are several subsets of homeotic genes. They include many of the Hox and ParaHox genes that are important for segmentation. Hox genes are found in bilateral animals, including Drosophila (in which they were first discovered) and humans. Hox genes are a subset of the homeobox genes. The Hox genes are often conserved across species, so some of the Hox genes of Drosophila are homologous to those in humans. In general, Hox genes play a role of regulatin…
