​The most common traits that have been put into GMOs are _____.

BlackTom AI · Accepted Answer

When considering the question about the most common traits that have been put into GMOs, we need to evaluate each option based on how frequently it has been engineered and discussed in GMO developments.
Option 1: 'increased size' — While size enhancement is a plausible trait in some breeding contexts, it is not among the most common or widely implemented GMO traits in major crops. Genetic modifications have tended to focus more on traits like resistance and nutritional modification rather than simply increasing size.
Option 2: 'herbicide resistance and insect resistance' — This pairing captures two of the most prominent and historically widespread GMO traits: crops engineered to withstand herbicides (allowing easier weed control) and crops engineered to resist insect pests (reducing damage and needing fewer chemical insecticides). These traits have dominated commercial GMO adoption and research, making this option highly accurate.
Option 3: 'improved nutrient value' — Nutritional enhancement (such as higher vitamin or mineral content) is an important area of GM crop research, but it is not as ubiquitous or historically dominant as resistance traits. It represents a more specialized subset of GMOs and has not reached the same level of widespread deployment as herbicide and insect resistance.
Option 4: 'toxic chemicals' — Intentionally adding toxic chemicals to GMOs would be unsafe and unethical for food crops, and is not a stated goal or common practice in commercial GM development. This makes the option clearly incorrect.
Option 5: 'drought tolerance' — Drought tolerance is an increasingly important target in biotechnology, especially for climate resilience, but it has not historically been the most common trait when looking at the early and large-scale adoption of GM crops. While relevant, it is not as prevalent as herbicide and insect resistance in the GMO landscape.

In summary, considering historical prominence and commercial prevalence, the combination of herbicide resistance and insect resistance stands out as the most characteristic and widely implemented GMO traits among major crops, whereas the other options describe valuable goals but not the dominant pattern observed in GMO deployment.
