it depends on which genes are being transferred and whether it confers
any advantage in the wild.

Thus RR genes are irrelevant but insecticidal ones may well not be.

Resistance to Roundup or Liberty is not "irrelevant", as it means that
weedy plants might have to be eliminated using stronger herbicides
such as atrazine. One of the supposed benefits of Chardon LibertyLink
(LL) is to remove the need for atrazine...
