What are GMOs?

Genetically modified organisms (GMOs) are defined as organisms whose DNA has been altered through genetic engineering techniques to exhibit desired traits. This modification often aims to enhance agricultural advantages such as increased resistance to pests, improved nutritional content, better yield, and adaptability to environmental stresses such as drought.

In contrast, the other options represent different agricultural concepts that do not engage in genetic modification. For example, plants grown in natural soil without alterations refer to conventional agriculture, where crops are cultivated without any genetic manipulation. Similarly, organic crops are produced using traditional farming methods that avoid the use of synthetic chemicals and genetic modifications, adhering instead to natural soil and ecosystem health practices. Lastly, selectively bred animals focus on traditional breeding techniques over generations to enhance certain traits, rather than employing direct genetic manipulation found in GMOs.

The emphasis on altering DNA for specific advantages is what distinctly characterizes GMOs, setting them apart from these more conventional agricultural practices.
