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
When the ratio of domesticated radishes to wild radishes in the field increased, the speed with which the flower color passed to the wild radishes also increased.
