Virtually every commercial fruit orchard in Noth America contains genetically identical trees. In apples, for instance, the M.9 or M.26 rootstocks are commonly used, which have been clonally propagated from the original plants for at lkeast the last 30 years. To these roots, genetically identical grafts of other varieties (i.e. McIntosh, Gala, Mutsu, etc.) are attached. They are, therefore, not only "clones" (evil) but also "frankenfoods" (so evil). Run!
