Is red hair really a sign of persistent starvation?

Magic * Me

I heard someone say it is. Like, if a people's been starved through generations or something their kids begin to have red hair and something. That true?

Answer
Not at all lol.

Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein.
Red hair can originate from several changes on the MC1R-gene. If one of these changes is present on both chromosomes then the respective individual is likely to have red hair. This type of inheritance is described as an autosomal recessive mode of inheritance. Even if both parents do not have red hair themselves, both can be carriers for the gene and have a redheaded child.

In rare cases red hair can be associated with a disease or genetic disorder.

In cases of severe malnutrition, normally dark human hair may turn red or blonde. The condition, part of a syndrome known as kwashiorkor, is a sign of critical starvation caused chiefly by protein deficiency, (melanin found in protein is what genetically determines hair color, so a deficiency in protein would lead to a loss of eumelanin, which is an amino acid responsible for making hair and skin darker) and is common during periods of famine. (This is probably what you are referring to. this does Not happen genetically or change a persons genetics. It is the direct result of loss of protein due to starvation. It would not be carried on through generations.)
One variety of albinism (Type 3, aka rufous albinism), sometimes seen in Africans and inhabitants of New Guinea, results in red hair and red-colored skin.
Red hair is found on people lacking pro-opiomelanocortin.

Is red hair an example of incomplete dominance?

Daphne

This seems very likely. In 1999, a geneticist studied this phenomena very closely. He observed a family where both the mother and the father (P generation) had blond, and four children. The three children inherited the blond hair, except the youngest who inherited the red hair.
This phenomena isn't explained in Mendel's laws of inheritance. He only mentioned that two alleles seperate during gamete formation and t hen combine.
Very strange.

Answer
In this case, blond could be dominant over red, so if the parents were both Bb, there could be a BB, Bb, Bb, and bb offspring, which would result in 3 complete dominance blondes and one totally recessive redhead. If what I remember is true, blond is totally dominant over red in human hair color.

What causes red hair?

Answer
The pigment pheomelanin gives red hair its distinctive color.
Red hair is associated with fair skin color because of low concentrations of eumelanin throughout the body of those with red hair.This lower melanin-concentration confers the advantage that a sufficient concentration of important Vitamin D can be produced under low light conditions.
The genetics of red hair, appear to be associated with the melanocortin-1 receptor (MC1R), which is found on chromosome 16.Red hair can originate from several different changes on the MC1R-gene. If one of these changes is present on both chromosomes then the respective individual is likely to have red hair. This type of inheritance is described as an autosomal recessive mode of inheritance. Even if both parents do not have red hair themselves, both can be carriers for the gene and have a redheaded child.

what is the chance my 2nd son will have red hair?

KristySEK

I have bright red hair my 1st child has red hair. will his lil brother have it too? My husbands mom's hair is a shade of red looks more brown. My brother and I are the only ones who have red hair in my family. Does anyone know the chance of my 2nd son having red hair too? I hope so :)

Answer
Hair color is controlled by several genes (at least 5). There are many shades of hair color, and creating a pedigree can be quite complicated.

What is the likelyness of my child having red hair ?

red hair inheritance image

JenJenxx

My dad and sister have red hair, but me and my brothers all have brown hair. I look nothing like my dad and take after my mum [hair colour and I look the spitting image].
My partner also has brown hair, however his sister has strawberry blonde hair, and his grandad has red hair.
What would be the chances of our child being born with red hair, we both have brown so would it still carry through ?

Answer
Red hair is a recessive inheritance pattern. What that means is that to have red hair a person must have two copies of the red hair gene (lets call it r), if they have only one copy, their hair won't be red because the second gene will be dominant over the single red one. So if r = red hair you have to have rr to actually have red hair, if you have rx (x being anything else) then you carry a gene for red hair that can be passed on to your children but don't actually have it yourself. So considering that both of your families do have redheads there is a chance that both you and your partner have one r gene each. If you have a child then IF both of you have that r gene there is a 25% chance of your child having red hair, remember that is if you both have that one copy of the r gene, which you really can't figure out from sight alone.

Overall I would say it is a small chance, but it impossible to pinpoint an exact percentage! Besides red hair isn't a bad thing!

What percentage of the world population has red hair, and why?

Butterfly

Why is red hair so rare? Sources please if you can.

Answer
hers a link. theres more info. veeeerrry interesting.

Some of us are drawn to the color Red like a bull in Spain, relentless, fixed, and pure. Less than four percent of the world population has naturally red hair. That is less than two percent in America. The gene for Ginger hair was discovered in 1995 and this discovery got little attention. This is not consistent as red heads have gotten lots of it. Some negative such as the association with witches and a crazy temper. Some are positive, such as our love for Lucy, The Little Mermaid, and the Feminist icon of Lilith, the first wife of Adam who insisted on sexual equality. So many deceptive MYTHS are of common knowledge concerning the crimson strand. Read up on the TRUE history of this striking genetic endowment.

Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein. It is associated with fair skin color, lighter eye colors (gray, blue, green, and hazel), freckles, and sensitivity to ultraviolet light.//

Biochemistry and genetics
A close-up view of red hairThe pigment pheomelanin gives red hair its distinctive color. Red hair has far more of the pigment pheomelanin than it has of the dark pigment eumelanin.

The genetics of red hair, discovered in 1997, appear to be associated with the melanocortin-1 receptor (MC1R), which is found on chromosome 16. Red hair is associated with fair skin color due to low concentrations of eumelanin throughout the body of those with red hair. This lower melanin-concentration confers the advantage that a sufficient concentration of important Vitamin D can be produced under low light conditions. However, when UV-radiation is strong (like in regions close to the equator) the lower concentration of melanin leads to several medical disadvantages, such as a higher risk of skin cancer.

The MC1R recessive variant gene that gives people red hair and fair skin is also associated with freckles, though it is not uncommon to see a redhead without freckles. Eighty percent of redheads have an MC1R gene variant,[5] and the prevalence of these alleles is highest in Scotland and Ireland. The alleles that code for red hair occur close to the alleles that affect skin color, so it seems that the phenotypic expression for lighter skin and red hair are interrelated.

Red hair can originate from several different changes on the MC1R-gene. If one of these changes is present on both chromosomes then the respective individual is likely to have red hair. This type of inheritance is described as an autosomal recessive mode of inheritance. Even if both parents do not have red hair themselves, both can be carriers for the gene and have a redheaded child. (Red hair genetics).

What hair color would our kids have if my boyfriend and I had a kid?

red hair inheritance image

Amber

I have red hair and my boyfriend has dark brown hair. We are comparing if our child would have red hair (like its momma) or dark brown hair (like its daddy). We both have brown eyes and thick hair. What hair color will show up on our child if we have a child together? His dad is dark brown hair and his mom has light brown hair and my mom has blonde hair and my dad has black hair.

Answer
Human hair colour inheritance is very complicated and it involves something like 6 different genes, if my memory serves me correctly. Therefore it's very random and hard to determine with any uncertainty. If I were a human genetics specialist I might be able to give you a better idea, but I think it's unlikely that the child will have red hair, as it has a tendency to 'skip' generations, as it were. Dark brown is most likely, but they could still potentially have quite light brown hair.

Just wait and see! :)

Can a mother with red hair and a father with blonde hair?

2.A son with blonde hair
3.A son with red hair

please only answer if you know, or post a site where i can find out.

NOOOOOOOOOOOOOOOO!
she cheated on him!?

light hair is recessive, dark is dominant.
both mother and father have light,
daughter 1 is dark haired.

i dont think it was possible.

Answer
Firstly, hair colour (unlike curly or straight hair) does not work in the dominant/recessive way.

Hair colour is mainly determined by the amount of eumelanin the hair has. Higher amount of eumelanin makes darker hair. Red hair has more eumelamin than blonde hair, and black hair has the most eumelanin.

The amount of eumelanin in the hair depends on many genes. To put it simply...we can say it depends on how much "ON" and "OFF" eumelamin genes the hair has.

A child will inherit 50% of his/her eumelamin genes from mom and 50% from dad. If in total, the child inherit more of the "ON" eumelamin genes, he/she will get darker hair colour. On the other hand, if in total, the child inherit more of the "OFF" eumelanin genes, his/her hair will be in a lighter shade.

Secondly, hair colour is not a sex-linked inheritance, so it will not matter if child is female or male.

Hope this helps.
