Redhead Genetics 101

I hope this little diddy inspires some of you beautiful people to contribute to my "Obsession du jour"
 
Carinhosamente,
Larry Eaton, "Ginger Scientist"

(From Wikipedia)

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.

 

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,(10% in Ireland & Scotland) 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 change in the MC1R protein. It is associated with fair skin color, freckles, and sensitivity to ultraviolet light, as the variant MC1R protein is found in the skin and eyes instead of the darker melanin.

 

Cultural reactions have varied from ridicule to admiration; many common stereotypes exist regarding redheads and they are often portrayed as “fiery-tempered,” and it’s genetic.

 

A 2007 report in The Courier-Mail, which cited the National Geographic magazine and unnamed "genetic scientists", said that red hair is likely to die out in the near future. (I disagree)

Red hair is a genetic mutation.Red hair is seen on the heads of only four percent of people. Most of these exist in the U.K., the Republic of Ireland, and Australia. The highest percentage of natural redheads in the world is in Scotland (13%), followed closely by Ireland with 10%. In the US, about 2% of the population are natural redheads.There is a belief that redheads are prone to industrial deafness. This actually could be true as the melanocytes are found in the middle ear.The color Green tempers red. Look at a color chart. This is why redheads are taught as children to wear lots of green. As if red hair is a shameful state of being.

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.
