I’ve posted notes for this week’s lectures. Since snow prevented us from meeting in person last Thursday, we’ll devote the first part of Tuesday’s lecture to discussing any questions that arose from the practice exercise. (You did take my advice, and try it, didn’t you?) We’ll take as much time as we need to discuss any questions you have before moving on to discuss how to estimate viabilities from data. If there’s time, we’ll close by discussing how the dynamics of viability selection with multiple alleles differ from those with only two alleles present and how fertility selection differs from viability selection.
