People around the world are different from each other with such differentiating traits being clearly visible. Such differentiating traits are seen in eye color, skin tone, height, and even hair color. These traits are carried in our human genes and passed on from parent to offspring. For instance, ever heard of the phrase “Redhead”? It is a popular term that people use for people with red hair.
Undoubtedly, the red hair looks amazing and is also considered as the desired color in many parts of the world, but red hair is also associated with mythical creatures like vampires and witches. But, keeping all the presumptions aside, Red remains one of the rarest hair colors found in humans.
In genetics, red hair is rare because the allele for red hair is recessive and is thus dominated by other colors. Scotland and Ireland take the spot of having the greatest number of redheads in the world. The pigment of red hair is pheomelanin, which is very rare.
The combination is extremely rare to find because blue eye color is also a recessive trait. Genetics explains that for someone to have red hair and blue eyes, their parents must be carrying that very gene. Out of the total redhead population, only 17% of the people have blue eyes. The majority have brown or hazel eyes
Left-handedness is a recessive trait, and that is why, these two genes generally show up together, making most redheads left-handed. Interesting right?
But the upside is, their hair is comparatively thicker, making it easy for them to be styled.
research confirms that redheads feel colder or hot compared to those with different hair color. The reason is still fairly a mystery but doctors suspect that MC1R might be over-activating the temperature detecting gene.
No everyone can gladly watch and accept their hair turn gray as a natural aging process. Redheads, on the other hand, don’t have to worry about this since their hair never turns gray. Once their radiant color starts to fade, it changes into a glorious spectrum of faded copper to rosy-blonde colors, then to silvery-white.
Actress Jane Seymour is a perfect example who is 67 years old and still has reddish-brown hair.
This comes out to be an advantage and a disadvantage. Despite the low melanin count which translates to poor UV protection, low concentrations eumelanin allows them to produce vitamin D within their bodies even in low light conditions.
There is no specific evidence about this. Research says that bees cannot see the color red, and hence use their sense of smell. No reports of redheads smelling different have been found.
If both the parents carry the gene, there are 25% chances that their offspring will have red hair, and if both the parents have red hair then the child will definitely have red hair.
Redheads come from over 80 countries to Holland to celebrate the flame-haired genes. It was started in 2005 and the trait has been celebrated annually by thousands of people in a two-day event.
