Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A crop plant has been genetically modified to make it resistant to herbicides.Which is a possible disadvantage of introducing this new crop plant?
A
Loss of weeds reduces competition.
B
Some weeds might become resistant to the herbicide.
C
The crop plant is unharmed and produces a higher yield.
D
The new gene will appear in new generations of the crop.
Explanation: 

Detailed explanation-1: -HRCs have a great potential in the simplification of weed management. Handled judiciously, these crops may be beneficial to the environment by enabling no-till systems, thus reducing erosion or allowing for later weed control, which may increase biodiversity in the field.

Detailed explanation-2: -There are many risks associated with the production of GM and herbicide-resistant crops, including problems with grain contamination, segregation and introgression of herbicide-resistant traits, marketplace acceptance and an increased reliance on herbicides for weed control.

Detailed explanation-3: -Why might genetically engineering a crop to be herbicide resistant result in producing weeds that are herbicide resistant? The DNA in herbicide resistant crops does not affect insects. The weeds that are not affected by the herbicide are able to reproduce.
