Yep, they qualify - allopolyploids (as they are called) are valid species. In fact all of the standard 'breeds' of wheat are members of artificially bred species. The most common types of wheat grown today are hexaploids (twice hybridized), but even most of the tetraploid wheats are artifically produced (thought there *are* a few natural tetraploid wheats, I believe). I forget the species names for the domestic wheat species. |> I am also aware of Drosophila experiments, but again I do not know if there |> are any results relevant to my question. There was one claim for breeding a new species of Drosophila, but closer study showed that the experiment had started with an undiagnosed pair of sibling species. -- sarima@teradata.com (formerly tdatirv!sarima) or Stanley.Friesen@ElSegundoCA.ncr.com
