A crop grower compared genetically modified (GM) tomato plants with non-GM tomato plants.
Both groups were grown under the same conditions and exposed to the same insect pest. The results are for 100 plants in each group.
| Type of tomato plant | Plants damaged by the insect pest (%) | Mass of tomatoes harvested (kg) |
|---|---|---|
| Non-GM | 38 | 240 |
| GM | 9 | 330 |
Describe the genetic change made to produce the GM tomato plants.
Use the data to explain how growing the GM tomato plants could help to feed more people.
