By The Way...

This is bogus genetics.  It was not long about that someone said "blondes will go extinct!" using the same argument.  It presumes that only red-headed parents can have red-headed kids.  This is, of course, not true.  It's a very basic misunderstanding of how recessive traits work.

When a red head has children with a brunette, the resulting children have one red hair and one brunette hair gene, so while they aren't red headed, they are passing that red hair gene down to all their children.  Mathematically speaking, the number of genes for red hair stays constant.  A man with two brown hair genes and a woman with two red hair genes have an average of one red hair gene per person.  Their children get one gene from each, so *they* average one red hair gene per person.

If there is perfect mixing, you'll essentially see the genes spread out among the population, so red hair appears more random, more often the result of two parents with hidden red hair genes meeting than the result of parents with red hair meeting.

If 2% are red heads now, we can probably make the assumption that perhaps 6% of the US population has a red haired recessive that is hidden.  Using these numbers, we see that 5% of all hair genes are "red".  This means that if the population were perfectly mixed, you'd still see 1/400 babies born red-headed.  More to the point, once this equilibrium is reached, it will not go down.  You cannot eradicate a gene for something that is established in a population unless you prevent it from being passed.

My friend and her husband are doing thier part. They have added two more red-heads to the world.

Nice pic. Does Krissy let you (and photoshop) help her decide what color to die her hair?
