CAIE A Level Biology 9700 · Genetic technology
A country facing food shortages is considering approving genetically modified (GM) crops, such as herbicide-resistant soybean and insect-resistant cotton, as well as GM salmon that grow to market size more quickly than wild-type salmon. Local farmers and consumer groups have raised concerns about safety and ethics. Explain how genetic engineering could help meet global food demand, and discuss the ethical and social implications of using GMOs in food production.
5 marks, so the mark scheme is looking for about 5 separate creditworthy points. Making the same point twice in different words earns it once.
Explain means: Give the reasons or the mechanism: why or how something happens. Link each point to the next with because, so or which means. A list of facts with no links usually loses the reasoning marks.
