Of the recessive genes, the gene for red hair is a primary example. For red hair to be physically expressed in a person, that person needs to have two copies of the gene for red hair in their genotype. Two parents who carry the MC1R gene have a 25 percent chance of having a redheaded child. Like many recessive traits, red hair is rare in our population.
Are We Facing A Redheads Extinction?
Are redheads with blue eyes really going extinct?
Genetics , Health. Back in National Geographic and other press reported that redheads were an endangered species, and that the gene that produces natural red hair would disappear from the human gene pool in as little as 60 years. Since then, the urban legend about natural red hair soon becoming nothing more than a memory abound. However, this is not true and people with natural red, auburn and copper hair will still be born for the foreseeable future. The origin of this urban legend is probably based on a confusion between a mutation that causes a recessive gene, and natural selection. A mutation is a gene that changes enough to code a different protein sequence than the original gene. Not all mutations have a downright positive or negative effect: Blue eyes are a mutation, as are the ones that cause terrible hereditary diseases or a natural mutation that gives carriers a better resistance to the HIV virus.
The Mythbuster: Red Hair Is Going Extinct
In August , many news organizations reported that redheads or "gingers," as our British and Australian friends call them, would eventually become extinct. Other news outlets and blogs picked up the story, citing the "Oxford Hair Foundation" or "genetic scientists" who claimed that there would be no more redheads by as early as [source: The Courier Mail ]. It turns out that all those people were wrong. Redheads are here to stay and should be around well beyond
