Yes. If we understand where the gene is, we can then go through the natural process of hybridizing. Without hybridizing, none of us would be here. In that case, what it allows us to do genomically is just to track the fate of the genes. For a very low cost, we can find out which progeny of the genetic strains we want to select. We can find out which ones are carrying the genes we want.
