Homeotic selector gene
History

The homeotic selector genes were discovered through the genetic analysis of Drosophila over 80 years ago. Unusual disturbances were found in the organization of the adult fly, resulting in misplaced limbs, such as legs developing where antennae usually develop or an extra pair of wings developing where halteres should be. This discovery provided a glimpse to understanding how each segment acquires its individual identity.
