Red hair only occurs in 1 to 2 percent of people, do you have red hair?
That's interesting! I have brown hair. Are specific people more likely to have red hair?
Yeah it occurs more commonly in those that have western european descent.
So the UK area. Why is that?
Red hair appears most commonly in people with two copies of a recessive allele on chromosome 16  which occurs more in western european descent.
Does chromosome 16 only carry the hair color gene?
Mostly, red hair does vary though in hues from deep burgundy or bright copper!
