![]() ![]() Question: My hair is platinum blond, my boyfriend's hair is strawberry blond. Genetics, however, is very complicated and if the blond parent is a carrier for mutations on the MC1R gene, then the child could obtain mutations from both parents and have red hair. ![]() This would make the child a carrier, and more likely to be blond than have red hair. If the blond-haired parent has no mutations on the MC1R gene, the child would only inherit any MC1R mutations from one parent. Question: What would happen in a situation where 1 parent has red hair and one has blond hair? Would that pretty much be the same as 2 red-haired parents or would it just make a strawberry blonde more likely?Īnswer: The answer to your question is dependent upon the actual genetic mutations found on the MC1R gene. Some people would say, "blond with red highlights," "strawberry blond," or "auburn" when describing this hair color. If your hair appears blond or brown most of the time, then you would likely be identified as having that color hair. While the story is intended to demonstrate the hazards of placing material desires over a spiritual blessing, one has to wonder if Esau was simply suffering from the effects of kwashiorkor.Īnswer: It is very likely you carry some mutations on the MC1R gene, even if you don't have both copies or show frank red hair. As the story goes, Esau sold his birthright as the first-born son to his younger twin, in exchange for a bowl of soup. The Biblical story of Esau is fascinating in this regard, because the Bible describes Esau as covered in red hair. Severe malnutrition can lead to a condition known as kwashiorkor – the deprivation of protein and calories from an individual’s diet will lead to failure to thrive, edema, excessive hair growth, and depigmentation, along with the development of red hair. This form of albinism is most common in New Guinea and Africa. One type of albinism (type 3, or rufous albinism) demonstrates a phenotype of red hair and ruddy skin. Some people do not come by their red hair via the MC1R gene. The Malleus Maleficarum (a report on witches in the Middle Ages) states, “Those whose hair is red, of a certain peculiar shade, are unmistakably vampires.” Other Causes of Red Hair In the middle ages, those with red hair could be labeled as witches or vampires. The MC1R gene affects the binding of endorphins, which are the body’s natural painkillers. Interestingly, those with red hair demonstrate a reduced sensitivity to stinging pain (the type of pain encountered when receiving an injection). Redheads required 19% more anesthetic than their brown haired counterparts. Liem at the National Institutes of Health demonstrated an increased sensation of pain caused by thermal changes, and an increased need for anesthetic. People who have red hair are more sensitive to pain caused by burns and freezing than people with brown hair. It is important to note that people who have dark skin and MC1R mutations are also at risk for skin cancer. Unfortunately, the risk of cancer is increased even when there is no exposure to sunlight, so those with red hair should have regular check-ups with a dermatologist to monitor any skin changes. Redheads have an increased risk for melanoma, as the melanocytes in people with red hair do not produce the protective eumelanin pigment.
