What gene controlls the hair color and height?

Hair color and height are influenced by multiple genes rather than a single gene. For hair color, genes like MC1R play a significant role, determining the type and amount of melanin produced. Height is primarily influenced by a combination of genetic factors, with genes such as GDF5 and others contributing to growth and skeletal development. Overall, both traits are polygenic, meaning they are controlled by many genes interacting with each other and environmental factors.
