Adding mutations

In the genetic drift part we saw that genetic drift causes a loss of haplotypes from the population, and generates LD. More precisely, haplotypes 'drift' around in frequency until some of them are lost - others 'fixed' - if you keep going long enough, eventually all variation is lost.

If this was all that was going on, we'd all be identical!

Of course in real populations there is an opposing force: mutation. To see how this plays out let's add mutations to our model now.
