When will redheads go extinct?

Don't believe the hype; Redheads are NOT going extinct. Red hair is a recessive gene, and unless all people carrying such a gene die, then the trait will carry on. It is likely, however, that redheads will become more rare in the future. This is due to two factors: 1) some ethnicities don't carry the red-hair gene, and 2) the increased prevalence of interracial marriages.
