If you've got red hair, you've probably been the butt of many a cruel joke throughout your life.
The good news is that most of those jokes are nothing more than jokes; red hair doesn't actually make you a witch or a bringer of bad luck. And as far as we know, you won't turn into a vampire upon death.
The bad news? Well, some negative beliefs are actually fact.
For example, gingers really are at a higher risk of developing melanoma.
But the rest of the population isn't as safe as one might think.
The Secret Ginger Gene
She could be one of them!
Redheads, which make up only 2% of the world's population, possess two copies of a gene called MC1R.
A far greater amount of the population – 25% – contain only one MC1R gene.
And according to a study published in the peer-reviewed journal Nature Communications, having one MC1R gene causes the same amount of skin cancer cell mutations as having two – a 42% increase when compared to the rest of the population.
A slightly scarier way to put it is to say that individuals who possess one or two MC1R genes have a risk of skin cancer equivalent to 21 years of unprotected sun exposure.
But most people with one MC1R gene probably don't even know they're at an increased risk because a single copy does not typically change any visible features. As such, carriers of the 'secret ginger' gene, unlike actual gingers, have no way of knowing they need to take special care to prevent melanoma. This places them at an even higher risk of developing skin cancer than full gingers.
