Explain that GM crops may be resistant to insect attack or herbicides and may have increased yields.

Explain that GM crops may be resistant to insect attack or herbicides and may have increased yields.. Within Variation and evolution, this learning objective sits inside Genetic engineering for AQA Biology 8461. Focus on using ideas such as GM crops, yield accurately in your explanation. A strong response should define the core idea, describe the relevant biological process, and connect it back to the question wording instead of giving a vague definition. When revising, students should aim to explain the science clearly, include precise biological vocabulary, and show how the process or structure links to the wider topic rather than listing isolated facts.
