Q11

Many transgenic crops have been genetically engineered to have traits such as herbicide resistance. In at least four different crops the transgene has been found in nearby wild plant relatives of the cultivated crops. What is the most likely reason for this observation?
A. Crossing over in the wild plants
B. Gene flow from the crops to the wild plants
C. Genetic drift from the crops to the wild plants
D. Mutations in the wild plants that match the transgenes
