Roundup Ready corn is a transgenic crop that is resistant to the herbicide Roundup glyphosate.Which one of the following would be the greatest concern regarding Roundup Ready corn?
A)Transfer of Roundup resistance to other crops,such as soybeans
B)Eventual loss of this trait from Roundup Ready corn due to hybridization
C)Lower yields produced by Roundup Ready corn
D)Evolution of herbicide resistance in weeds that commonly infect cornfields

Question

Quizplus · Accepted Answer

The greatest concern regarding Roundup Ready corn is the evolution of herbicide resistance in weeds that commonly infect cornfields, which can render the herbicide ineffective and make weed control more difficult in the future. This can lead to increased reliance on other, potentially more toxic herbicides, as well as decreased crop yields due to weed competition. Transfer of resistance to other crops or loss of the trait from corn due to hybridization are both potential concerns, but are less pressing than the issue of herbicide resistance in weeds. Lower yields produced by Roundup Ready corn are not a concern, as this trait has been shown to increase yields compared to non-transgenic corn.
