WebDrift can also occur when a catastrophic event reduces a large population to a very small size. Genetic drift means that the gene pool shrinks and becomes less diverse, which is often the opposite of what happens during gene flow when interbreeding expands the gene pool and increases genetic diversity. http://gaworkshop.readthedocs.io/en/latest/contents/06_f3/f3.html
