Two species of plants that diverged 20 million years ago have accumulated an estimated 10 nucleotide differences in gene X.Species A has had an average population size of 3 million, while species B has had an average population size of 0.5 million.Both of these plants are annuals, with one generation per year.Suppose that a sequence analysis of offspring and parents shows that the actual total mutation rate is 1.5 per million.Assuming that all mutations are either deleterious or neutral, approximately what fraction of the mutations are deleterious?
