I’ve updated notes on the interaction of genetic drift with mutation, and to complement the notes, I’ve written a new simulation in R Shiny and Plotly to illustrate both the dynamics of allele frequency changes within populations and the distribution of allele frequencies among populations. I’ve also updated notes on the interaction of genetic drift and natural selection. I’m having some kind of a weird permission problem with my server. A copy of the PDF that I just linked to with the original name (selection-drift.pdf) and the same permissions (at least so far as I can tell) keeps giving me a permission error when I try to download it. I’ll leave temp.pdf on the server, but I hope to fix the permission problem, so it would be best not to link to that file until I get it fixed.
