what I meant is that we know what proteins the genes at that location will do.
"We know nothing of the proliferation that gene may have in a wild population, or how our modification will help or hamper the organism to adapt to a changing environment."
We don't know exactly, but we do know a lot more than nothing.
No, we don't. At best, we know a few of the reliable consequences of that gene locus. We know nothing of the proliferation that gene may have in a wild population, or how our modification will help or hamper the organism to adapt to a changing environment.
