Answer: Genetically-engineered genes can be transferred to wild plants in the area.
Step-by-step explanation: Gene flow between similar species is a common occurrence. It is possible for genetically-engineered genes in a crop plant to transfer to related species of wild plants. This could cause multiple problems. For example, if the genetically-engineered gene makes the plant immune to a weed killer, then wild plants that are considered weeds by the farmer would no longer be controllable with weed killers.
