Red hair is a relatively rare trait, occurring in only 1-2% of the global population. However, it is much more common in certain regions, such as Scotland, where up to 13% of the population has red hair.
Genetics of Red Hair
Red hair is caused by a mutation in the MC1R gene, which controls the production of melanin. Melanin is the pigment that gives hair, skin, and eyes their color. The MC1R mutation results in a reduced production of melanin, leading to red hair.
