Effective population size and the faster-X effect: an extended model.

Abstract excerpt

Current models of X-linked and autosomal evolutionary rates often assume that the effective population size of the X chromosome (N(eX)) is equal to three-quarters of the autosomal population size (N(eA)). However, polymorphism studies of Drosophila melanogaster and D. simulans suggest that there are often significant deviations from this value. We have computed fixation rates of beneficial and deleterious...
