<h2>Homeotic mutants </h2>
Explanation:

- Homeotic genes provide identity of organ and they become permanently switch off after completion of their work
- In Drosophila, these genes are tightly regulated by the activity of polycomb genes and is present in two patches, one path constitute antennapedia complex whereas another patch constitute bithorax complex
- Antennapedia complex expresses in the second thorax segment and is responsible for the formation of legs
- Besides formation of thorax legs it also expresses in the area of head
