Aren't navel oranges a genetically modified food? And that corn that has white and yellow kernels on the same ear?People have been experimenting with hybrids for a long time. Sometimes, hybrids appear on their own with a little help from our friends the insects and birds.
I agree, though, that this is an issue that can be developed for something good, or for something greedy. I guess it depends on who's minding the store.
