Final answer:
Homoeotic genes, or Hox genes, control the development and placement of body parts in an organism.
Step-by-step explanation:
Homoeotic genes, also known as Hox genes, play a crucial role in regulating the development and placement of body parts in an organism. They determine the identity of different body segments and control the formation of specialized structures. For example, in fruit flies, Hox genes help specify the formation of wings, legs, and antennae in specific segments of the body. These genes act as master regulators, ensuring that body parts are formed in their correct locations and according to the correct timing during embryonic development.
