Fast track hybrid speciation
Hybrids that maintain the parental chromosome number (homoploid hybrid speciation) and are fertile, are uncommon in plants and unknown in animals. In November 29 Science, Duncan Greig and colleagues at The Galton Laboratory, University College London, UK, show that homoploid hybrid speciation can easily occur between two experimental populations of yeast and the resulting hybrids are fertile (Science, 298:1773-1775, November 29, 2002).Greig et al. used the ability of Saccharomyces gametes to div
