Where are hemoglobin genes located in humans?
Quick Answer
Hemoglobin genes are found in clusters on chromosomes 11 and 16. They code for the proteins that carry oxygen in red blood cells.
The Full Story
Human hemoglobin genes are arranged in two main clusters: the alpha-globin genes are on chromosome 16, and the beta-globin genes are on chromosome 11. These genes produce the protein chains that combine to form hemoglobin, the oxygen-carrying molecule in red blood cells. Different globin genes are active at different stages of development, from embryo to adult. Mutations in these genes can cause disorders such as sickle cell disease and thalassemia.
