Redheads have a particularly high abundance of pheomelanin, with very little eumelanin, which ranges from brown to black. When it's activated, it causes melanocytes to specifically produce eumelanin over phenomelanin, which balances out an individual's ratio. Contrastingly, redheads are born with a genetic variant that causes MC1R to chemically function differently on melanocytes, which leads to less eumelanin and more pheomelanin production. These genetic variants are recessive, meaning in order to be born a redhead, either non-redhead parents are carriers 25 percent , or one parent is a redhead and the other is a carrier 50 percent ; or both parents are redheads almost percent. This makes redheads rare and unique both on the outside and inside.
