Which of the following best describes a GMO?

• A. An organism developed through selective breeding
• B. An organism modified with biotechnology to express desired traits
• C. An organism that reproduces naturally in the wild
• D. An organism produced without any human intervention

Answer: (B)

A genetically modified organism (GMO) is specifically defined as an organism whose genetic material has been altered using biotechnological techniques. This includes methods such as gene editing, recombinant DNA technology, and transgenic technology, which allow scientists to introduce new traits or characteristics that are not naturally present in the organism.

The key aspect that makes option B correct is that it emphasizes the use of biotechnology to modify the organism in a targeted way to express desired traits. This can include enhancements such as increased resistance to pests, improved nutritional content, or greater tolerance to environmental stresses.

In contrast to the other choices, selective breeding (mentioned in the first option) does not involve genetic engineering techniques but rather relies on the natural variation within a species. The third and fourth options describe organisms that develop spontaneous traits and evolution without human intervention and do not align with the definition of a GMO, which fundamentally involves human-directed genetic modifications.
