Every tutor here has got this wrong, don't copy off them.
Suppose that the population from question #1 (data is in table below) is experiencing inbreeding depression (F=.25) (and no longer experiencing natural selection). Calculate the new expected genotype frequencies (f) in this population
after one round of inbreeding. Please round to 3 decimal places.
