Can You Cross-Pollinate a Rose and a Daisy? Understanding Plant Genetics

No. Cross-pollination between different genera (Rosa vs. Bellis) is genetically impossible due to speciation barriers. Pollen cannot fertilize the ovule, or if forced, the embryo fails to develop.

Nature prevents such crosses because the resulting organism would be non-viable (like a dog-fish hybrid). Some closely related genera (e.g., orchids) can cross. Genetic engineering can move genes across genera, but that's lab work, not garden pollination.
