Question

Bt corn is a genetically modified crop that contains a gene from another species. Which characteristic does this gene give the plant

B. Drought tolerance
C. Taller stems
D. Insect resistance

Answer 1

The right answer is D.

The effectiveness of BT-Corn compared to conventional insecticide treatment  is very much higher:

* The plant itself produces the toxin that blocks the digestion of or target insects: the entire plant is protected where a treatment (out of neonicotinoids, very expensive and reserved to the seed treatment) allows only a protection of surface and must be renewed several times.

* The selectivity of the treatment is very superior: each variant of the BT molecule targets only a family of insects but we do not know the impact of their cumulative effects in the environment.
