Is gene for red hair dominant
WebJan 7, 2024 · A separate melanin pigment, called pheomelanin, is responsible for producing red hair. Interestingly, red hair is linked to a specific gene mutation (MCR1) that tends to be passed on from parents to children, and includes not only red hair but also freckles and sun sensitivity (check out our reviews of baby sunscreen !).

WebApr 28, 2024 · The answer is almost always: from both. The main gene that underlies red hair is Melanocortin 1 Receptor, or MC1R. As implied by its name, the protein that it encodes is a receptor that plays a role in pigment synthesis. This gene has several versions (alleles), one of which is related to red hair. WebPeople with red hair have a variant of the melanocortin-1 receptor ( MC1R) gene. This gene controls the production of melanin, the pigment that gives skin, hair, and eyes their color.
