Can you link that? And are you talking about similar species or is just a free for all?
Called zoonosis. Jumping species.
It isn’t a free-for-all. As pollination vectors, bees and other bugs, move from plant to plant looking for pollen, they don’t go straight from one frankenwheat to the next. They go from wheat to weed, to weed, to weed, to wheat, to weed, and as they do some genetic material is spread around and might get included into an adaptation by the weeds.
The weirder thing is this. While GMO crops are viable, they tend to return to being regular crops as the recessive genes fade over generations. If these thwere last tested in the early 2000’s then why are they popping up now. Monsanto or somebody is not being honest.

Here is one link. First hit when I googled “genes jump species.” There are others that could be worthwhile, but I wanted to get you an answer asap.
I didn’t read the entire thing, but info in the parts I skimmed is even worse that what I remembered reading several years ago.
