Final answer:
Genetically modified corn has been found in Mexico.
Step-by-step explanation:
True
Genetically modified corn has been found in Mexico. The development and transformation of maize (corn) from a wild grass called teosinte through selective breeding started thousands of years ago in what is now Mexico. The genetic modification of corn has led to concerns about the impact on biodiversity and the potential vulnerability of monocultures. The introduction of genetically engineered (GE) crops, such as Bt corn, has also raised questions about their effects on the environment and other organisms, such as caterpillars.
