Red hair = how?

I want to know how humans get 'red' hair. I mean naturally. What..um...originating country/culture does the gene come from?

Irish people have red hair. They also drink and fight a lot. Geez, aren't you up on your stereotypes, PG?

My little brother and mom has red hair. I think they are witches and should be burned. :)

THERE'S NOTHING WRONG WITH IRISH PEOPLE.

Don't the scottish also have red hair? Irish people are anything from blonde to brown hair from my limited memory.

And yes, I seriously don't know the answer to this question. Sorry for not being as racist as I can be *salutes* /sarc

I'm Scottish with red hair, but thats about all I know on the subject!

My family is Scottish and a little Irish, and no one has red hair... weird I know. But yeah, I would consider more Irish, Scottish and English people to have red hair than anywhere else, defenatly not China or Japan... *sniggers*

Actually, all human beings have red hair. But there are many different shades of red, and most of those tend to be very dark or very light.

Red hair genes come from us celts yes the Scottish, Irish, Welsh and even the English mainly but it can also occur as a freak event but I believe it was England and theres many a shade as we brits call them:

Carrot
Ginger
Auburn
and Oh S**t thats really red!

I am Irish with red hair!! *takes a shot of whisky* YOU WANNA FIGHT ABOUT IT?

As far as I remember, the Irish had very little red hair amongst them until the Scottish started immigrating. The scots are better known for the red, and alot of Americans with red hair are of Scots-Irish descent, like me. But my hair is dirty blonde. My sister is a red head though.

Heh, I still call my little brother "a carrot" or "carrothead" sometimes. :)

It's vikings!!!!!!!!

Very dark red hair is a Japanese trait.

I believe the scottish have the gene like everyone else said. I always liked red hair... :)
