Called “Carrot Top”… (Even though carrot tops are really green!)
Redheaded girls are in. Way in. Red Hot, you might say!
Only an estimated 2 percent to 5 percent of the U.S population is born with red hair
Despite the old folk tale that redheads are the result of interbreeding between brunettes and blonds, hair color is actually determined by a more subtle genetic influence. Jonathan Rees, a professor at the University of Edinburgh in Scotland,discovered that red hair is associated with a loss of function in the melonocortin 1 receptor gene
Studies show that at least 10% Scots have red hair and 40% carry the gene responsible for red hair Red hair seems to be more prevalent in Ireland and Scotland. Why? The selection people make for their partners based on physical characteristics may be relevant.
