It was more common to bump into a Viking with red or ginger hair than it was to meet one with blond hair. There’s historical and geographical evidence that strongly mentions that there were many Vikings who had red hair than you might be aware of. Contrary to what pop culture has us believe about Vikings, most of them didn’t actually fit the prototype of blond hair, blue eyes, and rugged looks. In fact, research suggests that genetic analysis of this Norse tribe found that a majority of Vikings had red hair. With some variants of the gene, red hair can also occur if you have just one ‘allele’ of this gene.

However, Caucasian males are more likely to have blue eyes than females, research shows. As for the combination of the red hair and blue eyes, little research has looked at which sex is more likely to develop this uncommon characteristic combo. Both parents can display recessive gene characteristics, and they can pass those to their children, too. For example, if both parents have red hair, a child receives mostly the genetic information for red hair, so the chances they will have red hair is almost 100 percent. Only 17% of the world’s population have blue eyes, and only 1 to 2% have red hair. In Ireland, an estimated 10 percent of the population has red hair, though about 40 percent of the Irish carry the recessive gene.

This gene is located on chromosome 16 and is responsible for producing the pigment eumelanin. When a person has two mutated versions of this gene, they are unable to produce eumelanin and instead produce the pigment pheomelanin, which is what gives their hair its distinctive red hue. Reddish-brown (auburn) hair is also found among some Polynesians, and is especially common in some tribes and family groups.

Meanwhile, the Romans were also noticing the abundance of red hair amongst the tribes they were encountering as their empire progressed ever westwards. The Balkans and Western Europe now became established as the geographical and historical homeland of red-haired culture. It was one that was observed by ancient writers who began to form their conclusions about the red-haired peoples they encountered.
Culture
Riverdale actress Madelaine Petsch is a proud natural ginger, as is House of Cards alum Kate Mara. The Hebrew word usually translated "ruddy" or "reddish-brown" (admoni אדמוני, from the root ADM אדם, see also Adam and Edom)[104][105][106] was used to describe both Esau and David.
According to the Special Broadcasting Service (SBS), about 35% of people in Ireland and Scotland carry the MC1R receptor and roughly 10% have red hair. Globally, only 1 to 2% of the population have red hair, which is why it’s quite rare to see Black people with the unique feature, but they do exist. Limited research suggests redheads may be more likely to be left-handed. In the Western hemisphere, 10 to 15 percent of people use their left hand dominantly.
Previous studies had shown that redheads inherit two versions of the MC1R gene that leads to red hair – one from their mum and one from their dad. It is now almost certain that native Irish and Scottish Celts were taken (probably as slaves) to southwest Norway by the Vikings, and that they increased the frequency of red hair there. And, yet, not every society had negative views of red hair; in Italy and Greece, it was historically viewed as very popular – perhaps due to its rarity in these parts of the world.
Pain tolerance and injury
A British ancestry company, BritainsDNA, is now offering parents the chance to see if their children might inherit the so-called "ginger gene," the Telegraph reports. The test will scan each parent's DNA for signs of the so-called MC1R gene that causes redheadedness. People with black and brown hair have abundant levels of eumelanin pigment, whereas the absence of eumelanin corresponds to white hair. Blonde hair is a result of low levels of both eumelanin and pheomelanin. Red hair is a special case, wherein the amount of pheomelanin pigment is greater than the level of eumelanin.
Scientists have now discovered that red hair is caused by at least 8 different genes. The team, led by Profs Albert Tenesa and Ian Jackson, looked at DNA from almost 350,000 UK Biobank volunteers. They found that some of the 8 genes identified as having a role in red hair work by controlling when the MC1R genes is turned on or off. The 45th parallel is also the traditional boundary between northern European cultures, where cuisine is butter-based, and southern European cultures, preferring olive oil for cooking. In France, the 45th parallel is the also limit between the northern Oïl dialects of French and the southern Occitan language. In northern Italy, it is the 46th parallel that separates German speakers (in South Tyrol) from Italian speakers.
The other theory is that the prevalence of red hair is directly proportional to the areas that the Vikings mapped as their trade route. In whichever case, it seems that the Vikings are mainly responsible for the widespread number of red haired individuals around these two countries in particular. The fact of the matter is that when it comes to association with red hair the Irish and the Scottish will always come to mind. Even though the global population of red haired individuals dwindles at below 2%, these countries have the highest concentration of red haired people globally.
The rare trait usually occurs in people who have rufous Albinism, which, in addition to red hair, can cause an individual to have golden or bronze skin as well as blue eyes. Slavic, Baltic and Finnish people are predominantly descended from peoples belonging to haplogroups R1a, N1c1 and I1. Their limited R1b ancestry means that the MC1R mutation is much rarer in these populations. This is why, despite their light skin and hair pigmentation and living at the same latitude as Northwest Europeans, almost none of them have red hair, apart from a few Poles or Czechs with partial German ancestry. The southern route followed the Mediterranean coastlines until Iberia, while the northern route diffused along the Danubian basin then the North European Plain until the Low Countries and the Baltic. Each group of farmer blended with indigenous Mesolitic hunter-gatherers over time, but those i the Mediterranean may have been genetically distinct from those of central and northern Europe.
As well as describing the Gauls, Germans, and Celts as predominantly red-headed – something that wasn’t true for everyone- the ancient writers portrayed them as warlike and uncivilized. “This might also explain why you occasionally see red hair on a black Caribbean person who has two black parents. By chance alone, it might be that they are both carrying a European mutation which has come together in their child,” Dr. George Busby an expert from the Wellcome Trust Centre for Human Genetics, added to the publication. One study found that between 1899 and 1905, more than half of non-Hispanic white people in the United States had blue eyes. Today, estimates suggest about 17 percent of people worldwide have blue eyes. Worldwide, red hair is quite rare, and just over 0.5 percent, or one in 200 people, are redheads — this amounts to almost 40 million people, the Daily Mail reports.
Intermarriage with other peoples with more dominant genes meant that the recessive red gene rarely had a chance to express itself and so was incredibly rare. The accounts of classical writers are quick to highlight red hair amongst the tribes they encountered in central and Western Europe. These tribes were regarded as barbarians by the Greeks, despite their military prowess and sophisticated art. However, this was most likely because they were non-Hellenic than because of their hair color.
The Proto-Germanic branch, originating as the R1b-U106 subclade, is thought to have migrated from present-day Austria to the Low Countries and north-western Germany. They would continue their expansion (probably from 1200 BCE) to Denmark, southern Sweden and southern Norway, where, after blending with the local I1 and R1a people, the ancient Germanic culture emerged. If the mutation for red hair was inherited from Neanderthal, it would have been from a Central Asian Neanderthal, perhaps from modern Uzbekistan, or an East Anatolian/Mesopotamian one. The mutation probably passed on to some other (extinct?) lineages for a few millennia, before being inherited by the R1b tribe. Otherwise, it could also have arisen independently among R1b people as late as the Neolithic period (but no later). According to the Washington Post, as our ancestors migrated from this region to the colder, darker climate of northern Europe, redheads had a survival related advantage over their darker skinned, darker haired counterparts.
Take Scotland and Ireland, for example, where around 12% of the population have red hair. In the array of possible natural hair colors, dark hues are the most common — more than 90 percent of people worldwide have brown or black hair. Africans and people from the Caribbean have also been known to don bright red hair due to a gene mutation in the melanocortin 1 receptor commonly referred to as MC1R. The special gene regulates melanin in skin pigmentation, the eyes, and hair. However, the distinctive trait only occurs in an individual when both parents carry the unique receptive gene.
Even though there are parts where red hair is more prevalent, there are still areas in Europe where you won’t find people with red hair. Chances are that they carry the recessive gene, but it isn’t dominant as you find in places like Norway and Finland (which perhaps further supports the theory that there were Vikings in Finland too). But, since this genetic trait is recessive, the arrival of the Norsemen likely played a significant role in the genetic activation of it. Recent studies on red hair genetic analysis show that there’s a unique sequence that is directly linked to the formation of red hair.
