Where is the Hox gene cluster located in the human genome?
GeneticsDevelopmental biology
Quick Answer
Human Hox genes are located in four clusters on different chromosomes. These clusters help guide the body plan during embryonic development.
The Full Story
In humans, the Hox genes are organized into four clusters: HOXA, HOXB, HOXC, and HOXD. They are located on chromosomes 7, 17, 12, and 2 respectively. These genes are crucial during embryonic development because they help determine the body’s front-to-back pattern and segment identity. Similar Hox clusters are found in many animals, showing how ancient and conserved this system is.
Key Facts
