Is the ginger gene more dominant?
Red hair is a recessive trait, which means that only those who get two “redhead” versions of the gene, one from the mother and one from the father, will have red hair.
It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up.
If one parent is a natural redhead, and the other carries the gene, that gives them a 50% chance of their child being ginger. However, if the other parent has no ginger genes, the probability of a ginger baby falls to 0%.
A McGill University study found that redheads could handle more electric shocks than those with different coloured hair. Other research discovered that gingers are better at handling stabbing or sharp pain.
Most (natural) redheads will have brown eyes, followed by hazel or green shades.
If two parents have any redhead genes, they can have a redhead child even if they both have dark hair. You may have met a redheaded kid with flaming red hair and freckles on his nose whose parents have dark or brown hair, without a hint of red.
Scientists think many genes contribute to hair thickness. Research indicates that the EDAR gene, which influences hair follicle development, plays an important role in determining hair thickness.
Red is the rarest hair color, according to Dr. Kaplan, and that's because so few MC1R variants are associated with the shade. “Only three variants are associated with red hair,” she says. “If a person has two of these three variants, they almost certainly have red hair.
The title of rarest hair colour/eye colour combination belongs to red haired folks with blue eyes. According to Medical Daily, both the blue eye trait and the red hair trait are recessive, so their likelihood of simultaneous appearance is pretty slim. Just ask anyone who's pieced together a Punnett Square.
Research has shown that people with red hair perceive pain differently than others. They may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications. However, studies suggest that their general pain tolerance may be higher.
Do gingers age well?
REDHEADS are significantly less likely to age badly.
According to their findings, those who carry a variation of the MC1R gene responsible for red hair, look around two years younger than they actually are.
If both parents are ginger, their offspring would be ginger. Reason: We inherit half our chromosomes for our father (23) and half from out mother (23), 46 in total. If both parents passed on a ginger 'infected' hair colour chromosome, the child would be ginger.
They don't need as much vitamin D
So when a redhead goes outside, he or she produces more vitamin D in a shorter amount of time than people with other hair colors. This gives an evolutionary advantage, since low levels of vitamin D can lead to ailments like rickets, diabetes and arthritis.
If you've got red hair, don't bother donating sperm at Cryos International, one of the world's largest sperm banks. "We have nothing against red-haired donors," Cryos agency director Ole Schou told msnbc.com Monday.
Some studies indicate that redheads are more prone to illness because they prefer to keep out of the sun and so lack vitamin D, or because their ability to absorb the vitamin is less efficient.
Lifespan: up to 20 years in captivity, 5-10 years in the wild. Special Adaptations: Males have an elaborate courtship dance where they throw back their heads, almost touching their tail!
Rarest kind of redhead
Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
Hair color comes from both parents through the chromosomes passed onto their child. The 46 chromosomes (23 from each parent) have genes made up of DNA with instructions of what traits a child will inherit.
The test will scan each parent's DNA for signs of the so-called MC1R gene that causes redheadedness. "Through a simple saliva test to determine deep ancestry, we can … identify whether an individual is a carrier of any of the three common redhead variants in the gene MC1R," said Dr.
Every generation will carry the ginger gene, though in your families recent history (until you were born) the gene was recessive, hence your parents and grandparents didn't have ginger hair. There's around 25% chance that your children will have ginger hair.
What race grows the thickest hair?
Caucasian hair usually appears thicker since it is more difficult to see through the scalp than other ethnic hair types. However, Asian hair is the thickest and coarsest hair of any ethnic group.
Both of your parents give you two pieces of genetic information, called alleles, that determine what your hair type will be. The two alleles from your biological father combine with two alleles from your biological mother, giving you four in all.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
At some point, you've probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world's population sport this shade.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
It's the most common mistake to assume that they are the same. Ginger is a more vibrant and intense orange tone, whereas the strawberry blonde tone is also considered to be copper tones but it's much softer and lighter. Ginger hair is the sole colour that has a natural copper tone.
Red is the rarest natural hair color in the world. Currently, only 1 to 2% of the entire population has naturally red hair. The gene for red hair color is recessive, meaning a child will only be a redhead if he or she inherits two copies of the red hair gene (MC1R).
Human eyes come in many colors — brown, blue, green, hazel, amber, and even violet or gray eyes. Gray eye color is one of the loveliest and most uncommon, a trait shared by only 3% of the world's population.

Redheads probably won't go grey. That's because the pigment just fades over time. So they will probably go blonde and even white, but not grey.
Do redheads feel the cold more?
We found that redheads were significantly more sensitive to cold pain perception, cold pain tolerance, and heat pain tolerance. Heat pain perception threshold was also lower, but not significantly so, in redheads.
The skin of a redhead is thinner compared to others and is derived from the ectoderm. Teeth enamel is also derived from the ectoderm and thus is thinner than usual. Since the enamel coating is thin, the inner layer of tooth-dentin is more visible and offers a yellowish appearance.
About 1–2% of people of European origin have red hair. Especially female redheads are known to suffer higher pain sensitivity and higher incidence of some disorders, including skin cancer, Parkinson's disease and endometriosis.
Red hair is the result of a genetic variant that causes the body's skin cells and hair cells to produce more of one particular type of melanin and less of another. Most redheads have a gene mutation in the melanocortin 1 receptor (MC1R).
Naturally Produce More Vitamin D
Per a study published in 2020 in Experimental Dermatology, redheads are more efficient at synthesizing vitamin D. The vitamin is crucial for bone health and may protect against depression and fight off colds.
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. Although almost everyone with red hair has two copies of the red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.
Because of the natural tanning reaction to the sun's ultraviolet light and high amounts of pheomelanin in the skin, freckles are a common but not universal feature of red-haired people.

- Red hair and blue eyes is the rarest combo in the world. ...
- Ginger haired people can change temperature quickly.
According to Health Magazine, redheads can produce their own vitamin D when exposed to low levels of light. 4. You may not need as much pain medication. The gene responsible for red hair (MC1R) also releases a hormone that is similar to endorphins which limit the feeling of pain.
So what does that all mean for your chances of having a red-headed child? Since you need two pieces of “red hair” DNA to have red hair, your child will only have red hair if they receive “red hair” DNA from both parents. Even if you don't have red hair, you can still pass on a red hair allele to your child!
Why can't gingers go out in the sun?
People with red hair produce little of the skin pigment called melanin that is good at blocking the sun's harmful light.
Natural red hair is harder to dye than other shades
Headstrong as it is, ginger hair holds its pigment much firmer than any other hair colour. If redheads desired to dye their hair to any other colour (why would you?), it would only have a noticeable difference after bleaching the hair beforehand.
To sum all that science up, red heads have a faulty MC1R receptor which doesn't switch on in response to the sun's UV rays. This means the yellow-red pheomelanin in their melanocytes cannot be converted into the brown-black eumelanin which creates a sun tan.
The Vikings maybe brought a few red-hair genetic variants over with them, but the majority of redheads were already here.” Previously it has been argued that Scotland's poor climate was responsible for the high frequency of the ginger mutation.
While redheads are born all throughout the world, they're more likely to crop up in the Northern hemisphere. Though about 1-2% of the general world population has the red hair gene, that percentage rises to 2 to 6 percent north of the equator.
The gene for red hair is recessive, so a person needs two copies of that gene for it to show up or be expressed. That means even if both parents carry the gene, just one in four of their children are likely to turn out to be a redhead.
Most redheads have a gene mutation called MC1R. This type of gene must be carried by both parents in order for a child to potentially be born with red hair. Lots of people carry the gene but don't have red hair themselves. This is often why we see red hair skipping a generation or even multiple generations.
What causes red hair? Red hair is a recessive genetic trait caused by a series of mutations in the melanocortin 1 receptor (MC1R), a gene located on chromosome 16. As a recessive trait it must be inherited from both parents to cause the hair to become red.

If both parents are ginger, their offspring would be ginger. Reason: We inherit half our chromosomes for our father (23) and half from out mother (23), 46 in total. If both parents passed on a ginger 'infected' hair colour chromosome, the child would be ginger.
Who carries the ginger gene?
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. Although almost everyone with red hair has two copies of the red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.
Redheads probably won't go grey. That's because the pigment just fades over time. So they will probably go blonde and even white, but not grey.
Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent. That's 13 million people, out of the 7.6 billion on Earth.
Both parents must possess the gene for a red-haired child to be born. Redheads have fewer strands of hair on their heads. If they both just have the gene but have brown hair lets say then there is a 1 in 4 chance of having a baby with red hair.
Red hair (also known as orange hair and ginger hair) is a hair color found in one to two percent of the human population, appearing with greater frequency (two to six percent) among people of Northern or Northwestern European ancestry and lesser frequency in other populations.
Less than 2% of the world's population has red hair. The highest concentration of redheads is in Scotland (13%), followed by Ireland (10%).
