Redhead genetic advantages
That's also why redheads have to be careful in the sun, as they're more sensitive to sunlight due to the lack of eumelanin. There's even more sorcery afoot when it comes to redheads and their superpowers. This dislike for redheads extended into ancient Greek and Roman communities. She says that according to research, redheads can handle pain more effectively than others, because of the MC1R gene mutation that gives their hair its color. If you are a redheaded, blue-eyed, lefty, then you are not only a genetic mutant but a statistical anomaly, and you should be heralded as a king or queen among men. Though ginger teasing is seen as harmless, at times it has caused real and serious damage to redheads around the world, and it needs to cease, as it is nothing short of bigotry against a class of people who have had it hard over the years.
DNA: Genotypes and Phenotypes
According to The Big Redhead Book , gingers make more vitamin D in their bodies than the rest of us normies. So now you can tell all of your redheaded friends that they're legit mutants. The researchers, from the University of Edinburgh in Scotland and Oxford University, reached their findings by sifting through the UK Biobank, a huge and unique genetic study of half a million people of European descent in Britain. A variant of MCPH1, haplogroup D, may have been positively selected for in modern humans — and may also have come from an interbreeding event with an archaic population Evans et al. These particular Neanderthal genes would have been useful for the modern humans arriving in Europe whose immune systems had never encountered the pathogens within Europe and would be vulnerable to them, unlike the Neanderthals who had built up generations of resistance against these diseases.

In , the University of Louisville discovered this hidden gift and hypothesized that the redhead gene, MC1R, may cause the human temperature-detecting gene to become overactivated, making readheads more sensitive to thermal extremes. Since it is unlikely that Neanderthals experienced such disturbances to their natural sleep cycles, they may never have expressed this gene, but in modern humans who can control our climate and for whom our lifestyle often disrupts our circadian rhythms, this gene is expressed more frequently. When you spray perfume or apply scented oil to ginger skin, it smells different than it does on blondes or brunettes. A rendt-Nielsen hypothesised that the increased tolerance was due to the genetic subgroups MC2R, MC3R and MC4R - that are found in those with red hair and affect the way in which the brain functions and processes pain. If you're ever in an emergency, you'd be fortunate to have a redhead on your squad to help you get through it. The same study that proved that gingers need more anesthetic than non-gingers also validated your cold redheaded friend, as it showed that redheads are more sensitive to thermal pain. Fortunately, scientists have shown that there are ways to decrease the risk beyond limiting sun exposure, and they're hoping that their study will lead to the development of a pharmacological solution.
Below, explore several examples of Neanderthal genes and the possible phenotypes that they would have displayed. People with ginger hair can't absorb sufficient Vitamin D due to low concentrations of eumelanin in their body. Because MC1R also caused the skins paleness it collects more vitamin D in low sun environments. Turns out it may be causing the temperature-detecting gene to work overtime, so it's literally affecting how temperature is perceived on a genetic level. Apparently, a side-effect of having red hair is that it makes you more sensitive to pain than other hair colours, because, genetically, pain receptors are linked to the mutated MC1R gene that causes red hair.
