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. Most of these are just a part of our genetic makeup, but some are the direct result of genetic mutations. Put simply, a genetic mutation is when something in our DNA doesn't quite do what it's supposed to.

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.

Only 1 to 2 percent of the population has red hair and only 17 percent have blue eyes. How crazy is that?
And when you meet a red head with blue eyes, you are looking at the rarest colour combination of all for human beings. Around 17 per cent of people have blue eyes, and when combined with per cent having red hair, the odds of having both traits are around 0. 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. Blue-eyed people are also more common in the Baltic regions of Northern Europe. Red hair originates from mutations in a gene involved in skin and hair pigmentation, called melanocortin 1 receptor MC1R on chromosome

That's approximately million people. That's according to a study by a German sex researcher who found that women with red hair had sex more often. A similar English study found that redhead gals had sex an average of three times a week, while our blonde and brunette counterparts have it twice a week. Shame the fellas weren't questioned, too. Because it holds its pigment tighter than any other hair colour, red strands need to have their pigment stripped before being dyed by bleaching which, of course, damages the hair. Stay red! Each strand of red hair is generally thicker than other shades which compensates for the fact that redheads have less hair.
