Abstract

In just the last few years, plant geneticists have made tremendous progress in identifying the molecular genetic basis of postzygotic reproductive isolation. With more than a dozen genes now cloned, it is clear that plant hybrid incompatibilities usually evolve via two or more mutational steps, as is predicted by the Dobzhansky-Muller model. There is evidence that natural selection or random genetic drift can be responsible for these incompatibilities.
