Oh yeast...
Greig, D. 2009. Reproductive isolation in Saccharomyces. Heredity. 102: 39-44.
"For one pair of species, hybrid sterility is probably caused by chromosomal rearrangements, but for all the other species, the major cause of hybrid sterility is antirecombination - the inability of diverged chromosome to form crossovers during F1 hybrid meiosis. Surprisingly, incompatibility between the genes expressed from different species' genomes is not a major cause of F1 hybrid sterility, although it may contribute to reproductive isolation at other stages of the yeast life cycle."
(This is supposed to be my paper for Wednesday. I didn't finish it on Wednesday, but I don't see any other Wednesday posts!)
