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.
WebFeb 28, 2024 · Hox genes exist in the DNA of many animals. What do homeotic genes do? Homeotic genes are essentially master control genes, which identify an area of the … WebHomeosis may be caused by mutations in Hox genes, found in animals, or others such as the MADS-box family in plants. Homeosis is a characteristic that has helped insects become as successful and diverse as they are. [3] Homeotic mutations work by changing segment identity during development.
WebDec 20, 2024 · Homeotic genes, and other genes with analogous functions in controlling cell fate, are therefore known as selector genes. Although homeotic genes were first identified through spontaneous mutations affecting adult flies, they are required throughout most of Drosophila development to determine segmental identity.

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.
