Genetically modified organisms (GMOs) are a great concern for people, but also are used and eaten daily all over the world. Give two examples of a positive trait we have genetically engineered in different GMOs. Be sure to explain why this is a positive trait or outcome for each.(3 points)
Example 1: Drought tolerance in genetically modified maize
Drought is one of the major challenges in agriculture, as it severely impacts crop yields and food security. Genetically modified maize has been engineered to possess drought tolerance, allowing it to withstand extended periods with limited water availability. This positive trait enables farmers to cultivate maize in arid and semi-arid regions, which were previously unsuitable for its growth. By enhancing the plant's ability to survive under water scarcity, this GMO helps ensure stable food production and contributes to feeding the growing global population.
Example 2: Enhanced vitamin content in genetically modified golden rice
Vitamin A deficiency is a significant health issue, particularly in developing countries where rice constitutes a major part of the diet. Golden rice, a genetically modified variety, was engineered to possess enhanced levels of beta-carotene, a precursor of vitamin A. This positive trait directly addresses the deficiency problem, as vitamin A plays a crucial role in maintaining good vision, a strong immune system, and overall health. By consuming golden rice, people can naturally obtain this essential nutrient, reducing the prevalence of deficiencies and related health complications. This GMO serves as a potential solution to combat vitamin A deficiency, especially in regions where alternative dietary sources of the vitamin are limited.
