Problem:
Question 1: What attracts the polymorphonuclear leukocyte to the injury site? Explain thoroughly.
Question 2: Derive the expression for effective population size under fluctuating N (i.e that Ne is the harmonic mean of the Ni's). You will want to start with the equation for the accumulation of identity by descent (f) under finite population size, and employ the approximation that ln[1 - (1/x)] ? - (1/x), which is appropriate when x > 10 or so. Do it for 2 generations. Show your calculations, but you do not need to write out any explanation.
