Part One: How has increased knowledge about growth been applied to improving the resistance of some
plants to pests and allowed those plants to be used in non-native areas? What are the positive and
negative impacts of such applications?
Part Two: Farmed salmon can be genetically modified to reach market size in half the time of normal
fish, and cost half as much to feed. However, entire populations of wild fish could be endangered by
mating with bio-engineered fish that are released into the wild, with disastrous consequences for the
ecosystem. Why do you predict this is the case? Use your knowledge of genetics, and of genetic
disease to explain how genes in isolated populations can impact larger populations (25 marks) 5
