What characterizes genetically modified (GM) seeds?

Genetically modified seeds are characterized by their alteration to express specific traits, which have been achieved through biotechnological methods. This genetic manipulation allows for the development of seeds that may be resistant to pests, diseases, or environmental conditions, or seeds that can yield higher production or improved nutritional content. The specific traits are often inserted into the plant genome from other organisms, allowing for enhanced characteristics that would not typically occur through traditional breeding methods.

The other options do not accurately describe GM seeds. For instance, GM seeds are not defined by a lack of pesticide use; rather, they may be developed to reduce the need for chemical treatments. They are not exclusive to organic farming, as organic farming typically prohibits the use of genetically modified organisms. Furthermore, GM seeds are indeed utilized in agriculture, as they have been adopted in various crops globally for their beneficial traits. Therefore, the defining characteristic of GM seeds is their intentional alteration for specific expressible traits.
