Warwick, Legere, Imard and James. 2007. Do escaped transgenes persist in nature? The case of an herbicide resistance transgene in a weedy Brassica rapa population. Molecular Ecology.
1. Why is gene flow from transgenic crops into wild species a potential problem?
2. What are the key components of the process of introgression in this system?
3. Describe the unique information that was obtained using molecular and quantitative genetic approaches. Why was it valuable to use both approaches to tackle this issue?
4. Why is it significant that the transgene persisted over a 6-year period in the absence of herbicide selection pressure? How is this likely to differ from conditions in the field? What are the implications of this difference?
