Question
Transcribed Image Text:The bollworm is a pest that eats and damages corn crops. During their short lifespans, Bollworms hatch, eat,
mate, and lay eggs which hatch the following spring, In order to save her business, a local farmer has chosen to
use a pesticide toxin that's deadly to 90% of bollworms. The remaining 10% of the bollworm population is
carries a rare inheritable gene that makes them immune to the toxin.
The farmer switches to using the pesticide in 2006. At first, this seems to solve her problem: her first crop
showed very little sign of bollworm damage. As time went on however, the modified corn plants began to show
increasing signs of damage. Less than 10 years later, the plants showed nearly the same damage as the original
crops.
