- Sexual reproduction produces offspring with genetic material from both parents
- A crop of corn plants is genetically modified to produce a natural pesticide
- Corn plants reproduce through sexual reproduction
- Therefore, sexual reproduction between genetically modified corn plants produces offspring with genetic material that produces a natural pesticide

- If something required for a process is not produced then that process is prevented from occurring / cannot occur
- Reproduction of the plants often requires pollen
- Therefore, if pollen is not produced then plant reproduction is prevented from occuring

- If pollen is not produced then plant reproduction is prevented from occuring
- Corn is a kind of plant
- Hence, if the corn does not produce pollen, then the corn reproduction is prevented from occuring

- Sexual reproduction between genetically modified corn plants produces offspring with genetic material that produces a natural pesticide
- If the corn does not produce pollen, then the corn reproduction is prevented from occuring
- Hence, if pollen is not produced then genetically modified corn plants will be prevented from producing offspring with their genetic material

So, if pollen is not produced then genetically modified corn plants will be prevented from producing offspring with their genetic material
Question: A crop of corn plants is genetically modified so that the plants produce a natural pesticide. People are concerned that these corn plants might transfer modified genetic material to other plants. Which of the following is the best way to further modify the plants to prevent them from transferring their genetic materials to other plants?
