This sentance threw me off, and I now realize that I totally misinterpreted
what you were saying in that posting.  Since you wrote the size of the
population without the number of individuals that initially had the
mutation, I assumed that by "in which a mutation occurs," you meant that the
whole population had it.  When I read the posting, I was thinking "what's
this guy smokeing," and belted out my reply before I realized my mistake.
So my apologies, please ignore my last posting.
