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?

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).
