the technique can introduce the genes for whichever trait is desired,

the technique can also introduce genes governing the production of toxins or carcinogens,

and the undesirable traits of such genes might not be easily discoverable.

these latter undesirable traits------undesirable traits of the genes govering the production of toxins or C
