Red hair has far more of the pigment pheomelanin than it has of the dark pigment eumelanin. Red hair is also found amongst the Ashkenazi Jewish populations. The International Journal of Cancer reported in that natural redheads are approximately two and a half times as likely to develop the dangerous cancer as people with other hair hues. Copy cats Thanks to our natural awesomeness, and the greatness of famous redheads, people like to copy us. Dr David Gunn, a senior scientist at the company, said perceived age was a phenomenon everyone was familiar with. People with red hair are more likely to be left-handed Recessive traits often happen in pairs so commonly people with the gene for red hair also possess the trait for left-handedness.
Are redheads going extinct?
People with one red hair copy and one regular copy of the MC1R gene still make enough brown pigment and are normally not redheaded. Specifically, redheads have a mutated melanocortin-1 receptor MC1R gene that produces an altered receptor for MSH. For example, strawberry blonde is a little of each, auburn is some eumelanin and pheomelanin and a redhead is very little eumelanin and lots of pheomelanin. Most redheaded individuals are either homozygous or compound heterozygous for these variants. Like any other gene, the MC1R gene has the instructions for making a protein. This leads some to associate red hair with youthfulness, a quality that is generally considered desirable. Rick Sturm, a researcher in hair and skin genetics at the University of Queensland, told the Australian Broadcasting Company that "there's no shortage of red-heads" and that the Oxford Hair Foundation didn't provide sufficient scientific evidence to prove its findings [source:
Red hair is associated with fair skin color because low concentrations of eumelanin throughout the body of those with red hair caused by a MC1R mutation can cause both. Still several other variants were known to have weak associations with the red hair color. In Africa, for example, red hair is selected against because high levels of sun harm untanned skin. In Anne of Green Gables , a character says of Anne Shirley , the redheaded heroine, that "her temper matches her hair", while in The Catcher in the Rye , Holden Caulfield remarks that "People with red hair are supposed to get mad very easily, but Allie [his dead brother] never did, and he had very red hair.

Description: The comedian " Carrot Top " uses this stage name. Eighty percent of redheads have an MC1R gene variant,  and the prevalence of these alleles is highest in Scotland and Ireland. Our RedTracer DNA Test can help you uncover whether you carry any of the red hair causing variants. A copy of regular MC1R gene keeps most human from being redheads.
