Genetically modified corn is a type of corn that has been altered using biotechnology to enhance certain traits. This can include resistance to pests, tolerance to herbicides, or improved nutritional content. The modifications are made by inserting specific genes into the corn's DNA, allowing it to express desired characteristics. Farmers often choose genetically modified corn because it can lead to higher yields and reduced crop losses. This type of corn is widely used in various products, including animal feed and processed foods. However, its use is sometimes debated due to concerns about environmental impact and food safety.
