Botanist: In an experiment, scientists raised domesticated radishes in a field with wild radishes, which are considered weeds  Within several generations, the wild radishes began to show the same flower color as the domesticated ones
This suggests that resistance to pesticides, which is often a genetically engineered trait, would also be passed from domesticated crop plants to their relatives that are considered weeds
It is more difficult for flower color to be transferred between domesticated and wild radishes than it is for almost any other trait to be passed between any two similarly related plant species.
