Explain insect resistance, Biology

Assignment Help:

In 2003 nearly 70 million hectares globally were planted in genetically modi?ed crops.

Of these, 73%  were plants such as soybean, corn and cotton, which were modi?ed to be herbicide tolerant and 18%  were plants such as maize and cotton, which were modi?ed to be insect resistant. A further 8% were crops with both herbicide tolerance and insect resistance. The remaining 1% were modi?ed in other ways.

Compare and contrast the possible outcomes of releasing into the environment, plants genetically modi?ed for herbicide tolerance with those of plants genetically modi?ed for insect resistance. Your answer should include both the ecological and evolutionary outcomes of such releases, and evaluate the likelihood of these outcomes occurring.
