There is concern that transgenic genes have been found in unrelated crops. Could such genetic transformation occur
without traditional breeding programs? What will be an ideal response?
ANSWER: Yes, recombinant DNA can escape into the environment. For example, glyphosate resistance
genes are probably being transferred from transgenic plants to nontransgenic ones via pollen
carried by wind or insects.
