It is generally believed that all human beings share approximately 98 percent of their genetic makeup. Over the centuries though, DNA has evolved, changed and mutated, so some of us bear little similarities to our ancestors in regard to things like physical features and height. Even though many people go to great lengths to appear like everybody else, we almost all have something that makes us different from the next person. Usually it's a personality trait, some skill we know, or a talent that not many people have. Some of us, however, have physical characteristics that make us stand out in a crowd: such as our height, complexion, or the shapes of our faces.

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.

The reason these looks are so unusual is because they are the result of two different sets of DNA instructions, or mutations, happening in the same person, explains Professor Mark Elgar, an evolutionary biologist from the University of Melbourne. In contrast, brown hair and brown eyes are dominant traits, which is why they are much more prevalent. In some regions of the world, red heads are more common, making up per cent of the population in Scotland and Ireland for example.
