This is a really great resource, perfect for brushing up on some difficult areas that aren’t covered that much in the usual texts e.g. Hartl and Clarke. I noticed in section 4.5.1, equation 90, I think the sign is wrong (should be negative on one side), giving

s\gamma(x)q(x)(1-q(x))=-\frac{\sigma^2}{2}\frac{d^2q(x)}{dx^2}

Also, I found it very slightly confusing that at the top of page 30 the sink location is described as receiving a contribution g(\Delta x) from the location x+\Delta x, when in fact it is receiving this contribution from x-\Delta x. Of course, due to the symmetry of the normal distribution, you get the same answer using g(-\Delta x).

My question is, what is the probability of NOT inheriting from say two, three, four, or all m of the ancestors within a given generation?
