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. WebHomologs of the Drosophila homeotic selector genes have been found in almost every animal species studied, from cnidarians (hydroids) and nematodes to molluscs and mammals. Remarkably, these genes are …
