According to research published in Current Biology, people with the MC1R gene, aka the gene that produces red hair and fair skin, tend to look several years younger than their non-ginger counterparts. Redheads are more likely to be left handed than any other hair color. Red hair is a recessive gene as is being left handed (so the scientist claim). Apparently recessive genes travel in pairs because there are more left handed red heads than there are any other left handed brunettes or blondes.

Description: One author of the study, Dr. Daniela Robles-Espinoza, explained why redheads are more sensitive to UV rays and much more prone to melanoma, which has to do with the variant gene's inability to. A research within the journal Nature Communications discovered that many individuals carry one variant allele of the MC1R gene (it takes two to be a redhead). The twist, based on Robles-Espinoza, is there are various individuals who carry the variant gene and will have an analogous degree of threat as card-carrying redheads. Technically MC1R is not the gene for redheads. MC1R is just the gene most associated for all hair color. It's the VARIANT in that gene that causes red hair. So for example, my MC1R variant SNP is rs, known as ArgTrp or RW. It's the red hair gene most commonly found in Ireland and sometimes Iceland.
