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. WebThe term "Mox genes applies to clusters of homeotic gonas found in many different animals, including fruit flies. After segmentation ons have established the body segments, Hox genes trigger the development of segment-specific body structures in the correct locations.
