Answer:
Moth populations should be monitored in both, normal wheat and engineered wheat
Explanation:
Genetically engineered wheat crop means that the genome of the wheat is being manipulated by the techniques of biotechnology. Gene for the resistance to moths is introduced into wheat in order for plant to become protected. Determination of resistance should be performed via monitoring of control group (normal wheat, not resistance to moth) and engineered wheat (potentially resistant) and their comparation. Moth population should be decreased in the resistance plants.
