ABOUT THIS CLUB
I've noticed recently that here on CS, a large portion of our community has red hair! I'm a natural red-head myself, and figured why not have a club for our awesome genes? This club is not meant for us to discriminate on other hair colors; it's just for us red-heads to meet and share stories, converse about genes, etc.
WHO CAN JOIN?
Anyone who respects/admires/wants/or has the hair color! RULES ~ Respect the owner & moderators. If they feel you aren't being nice or fair & ask you to leave, please respect their wishes.
~ Any extreme hateful behavior will be reported.
~ Only the owner or moderators can make a new topic if this one reaches 800 pages. (taken from SITE,FORUM, & CLUB rules of CS)
~ The type of info we don't let you share:
~ Your full name, last name, age, grade, birth year, address, suburb, town, city, name of your school
~ Photos of yourself or your family/friends (except if your faces aren't visible)
~ Your email address or phone number & full names of your family members ~ Treat other members respectfully. If you have nothing nice to say, then perhaps say nothing at all. Any bullying or harassment of members will not be tolerated.
~ Please don't use bad language on the forum - Please don't swear or use other offensive language on the forum. Even if you don't have a problem with using that language, it's not fair on other members who may find it offensive. ~Keep topic/image content kid-friendly, please! - just imagine every other member is 10 years old and behave appropriately 
~ Do not post in a topic you do not like just to start a fight. You may post to discuss the opposite views but do not expect a warm welcome. ~ Though, this does not allow flaming someone who posts disagreeing with you.
~ Stay on topic. If you keep discussing the topic, the army/club will not be locked.
~ Also, if you find the need to report a multiple club, provide a link to the other club you are talking about.

Information on Red Hair: The People & The Gene
Red hair occurs naturally on approximately 1–2% of the human population,. It occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations. 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 varies from a deep burgundy through burnt orange to bright copper. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin. The term redhead (originally redd hede) has been in use since at least 1510. It is associated with fair skin color, lighter eye colors (gray, blue, green, and hazel), freckles, and sensitivity to ultraviolet light. Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered.Geographic Distribution Today, red hair is most commonly found at the northern and western fringes of Europe; it is associated particularly with the people located in the British Isles (although Victorian era ethnographers claimed that the Udmurt people of the Volga were "the most red-headed men in the world"). Redheads are common among Germanic and Celtic peoples. Redheads constitute approximately 4% of the European population. Scotland has the highest proportion of redheads; 13% of the population has red hair and approximately 40% carries the recessive redhead gene. Ireland has the second highest percentage; as many as 10% of the Irish population has red, auburn, or strawberry blond hair. It is thought that up to 46% of the Irish population carries the recessive redhead gene. A 1956 study of hair colour amongst British army recruits also found high levels of red hair in Wales and the English Border counties. In the United States, it is estimated that 2–6% of the population has red hair. This would give the U.S. the largest population of redheads in the world, at 6 to 18 million, compared to approximately 650,000 in Scotland and 420,000 in Ireland.GeneticsThe 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 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. However, when UV-radiation is strong (as 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 non-tanning 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, 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 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. OriginRed hair is the rarest natural hair color in humans. The non-tanning skin associated with red hair may have been advantageous in far-northern climates where sunlight is scarce. Studies by Bodmer and Cavalli-Sforza (1976) hypothesized that lighter skin pigmentation prevents rickets in colder climates by encouraging higher levels of Vitamin D production and also allows the individual to retain heat better than someone with darker skin. In 2000, Harding et al. concluded that red hair was not the result of positive selection and instead proposed that it occurs because of a lack of negative selection. In Africa, for example, red hair is selected against because high levels of sun would be harmful to untanned skin. However, in Northern Europe this does not happen, so redheads come about through genetic drift. Estimates on the original occurrence of the currently active gene for red hair vary from 20,000 to 100,000 years ago. A DNA study has concluded that some Neanderthals also had red hair, although the mutation responsible for this differs from that which causes red hair in modern humans.Source: http://en.wikipedia.org/wiki/Red_hair
