As a geneticist with a focus on human genetics, I can explain that red hair is not a mutation in the traditional sense of the term. Instead, it is a result of variations in the MC1R gene, which is associated with the production of melanin, the pigment that gives color to our hair, skin, and eyes. The variations in this gene can lead to the production of a type of melanin called pheomelanin, which results in red or reddish hair.
Red hair is a relatively rare trait, found in only about 1-2% of the human population. It is most commonly found in people of northwestern European descent, particularly those from Scotland, Ireland, and Wales.
While the term "mutation" often implies a negative or harmful change, the variations in the MC1R gene that lead to red hair are not typically harmful. In fact, they are a normal part of human genetic diversity. However, it is worth noting that individuals with red hair may have a higher sensitivity to sunburn and a slightly increased risk of skin cancer due to the way pheomelanin interacts with UV radiation.
In summary, red hair is a result of genetic variation, not a harmful mutation. It is a fascinating example of how genetic differences can contribute to the diversity we see in human populations.

About 1 to 2 percent of the human population has red hair. Redheads have genes to thank for their tresses. Research shows red hair usually results from a mutation in a gene called MC1R, which codes for the melanocortin-1 receptor. The pigment found in redhair that makes it red is called pheomelanin.
