Most of the wheat,rice,and corn raised in the world has resulted from genetic engineering of one sort or another,either by crossing certain varieties or deliberately transferring genes using transgenic techniques.These methods select for plants that produce their own defenses against pests with chemicals or physical barriers.Helping to feed the world,this represents an example of
A)cultural control.
B)natural enemies control.
C)genetic control.
D)natural chemical control.

Question

Quizplus · Accepted Answer

The use of genetic engineering techniques to select for plants with improved qualities such as resistance to pests represents genetic control. This involves the deliberate manipulation of genes in the organisms to achieve the desired traits. Cultural control involves changing the physical and environmental conditions to make it difficult for pests to thrive, natural enemies control involves using other organisms to control pests, while natural chemical control involves using natural compounds to control pests. None of these methods involve genetic engineering.
