Where does the ginger hair come from?...is it only from ireland or can other europeans have it,spaniards,italians,british you get the point.
Also,if an american has ginger hair could we assume they have irish ancestors?
Answer
red hair occurs naturally on approximately 1â2% of the human population.[1] It occurs more frequently (2â6%) 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.[2] It is associated with fair skin color, lighter eye colors (gray, blue, green, and hazel), freckles, and sensitivity to ultraviolet light.[3]
Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as fiery-tempered.
In fact the USA, has the most red heads. It is estimated that 2â6% 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.
The 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. So the more pigment pheomelanin the brighter your hair is.
Origins
Red 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.[30] 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.[27]
Estimates on the original occurrence of the currently active gene for red hair vary from 20,000 to 100,000 years ago.[31][32]
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.[33]
Red hair is a gene basically. It is in your DNA. You inherit it, it doesn't come from a particular place. Many think Scots or Irish are where you find the most red heads, but in fact it is the USA.
All from Wiki...Plus my brain...And other sites...Plus I saw some of it in a book. So I got it from various things.

If you have natural red hair, does that mean you carry the redhead gene?
~*~Lacey~*
If your hair is red, are you more likely to have a kid with red hair than someone who also carries the gene, but doesn't have red hair??
Answer
Red hair (also referred to as titian or ginger hair) varies from a deep orange-red 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. People with red hair are often referred to as redheads or gingers.
Approximately 1% to 2% of the human population has red hair. It occurs more frequently (between 2% and 6% of the population) in northern and western Europeans, and their descendants, and at lower frequencies throughout other parts of the world.
Red hair appears in people with two copies of a recessive gene on chromosome 16 which causes a mutation in the MC1R protein. This means that :-
(a) If you are red hair and married a person with red hair. You will have kids with red hair only.
(b) If you are red hair and marries a person with no red hair and do not carry the genes for red hair. All your kids will not have red hair.
(c) If you are red hair and marries a person with no red hair but they carry the genes for red hair. You might get some kids with red hair and some without red hair.
