120 views
The MC1R gene on chromosome 16 is primarily responsible for determining hair color. This gene controls the production of melanin, which includes eumelanin (black or brown pigments) and pheomelanin (red or yellow pigments). The specific variants and interactions of the MC1R gene largely dictate whether someone will have blond, brown, black, or red hair. However, other genes also contribute to the nuances of hair color and how it may change over time.
FAQs & Answers
- Which gene is responsible for hair color? The MC1R gene on chromosome 16 primarily determines hair color by controlling the type of melanin produced.
- How does melanin affect hair color? Melanin includes eumelanin, responsible for black or brown hair, and pheomelanin, which produces red or yellow pigments, determining hair color.
- Are other genes involved in hair color besides MC1R? Yes, while MC1R plays a major role, other genes also contribute to hair color variations and changes over time.
