homeotic genes

Homeotic genes are a group of genes that control the development of an organism’s body plan by determining the placement of body parts, such as limbs and organs. They act like biological instructions, guiding cells on where to grow specific structures during development. Think of them as an internal blueprint that ensures everything ends up in the right place. These genes are highly conserved across many species, highlighting their fundamental role in building complex organisms. When these genes malfunction, it can lead to improper formation or placement of body parts, illustrating their critical importance in development.
