It tastes bad.
It is too expensive to produce.
What is one concern critics have about GE foods?
GE foods will taste too strong.
People won’t like the color of GE foods.
Moving genes between unrelated species might cause unexpected health effects.
They will be too hard to find in stores.
How have humans traditionally altered plant genetics?
By cooking food longer.
By freezing plants in special labs.
By using only chemicals.
By saving seeds and breeding varieties with better traits.
What is one surprising example of modern genetic engineering?

What are biotech foods?
Biotech foods are made only from fruits and vegetables.
Biotech foods are produced from animals and plants that have been genetically altered.
Biotech foods are made in laboratories without any real plants.
Biotech foods are completely natural and unaltered.
How is genetic engineering different from traditional breeding?
It requires the use of robots.
It allows transferring just a few genes between unrelated species.
It mixes all the genes randomly.
It only works with animals.
What happened with modified soybeans in the 1990s?
