Understanding Genetic Modifications in Crops
Genetic modification (GM) involves altering a plant's DNA to introduce desirable traits. Let's evaluate the given statements:
Statement Analysis
- A. Deteriorates nutritive value: This is generally incorrect. Genetic modification can be used to enhance the nutritional content of crops, such as Golden Rice engineered to produce Vitamin A.
- B. Reduce mineral usage efficiency in plants: This is typically false. GM crops can be designed to improve nutrient uptake and utilization efficiency, reducing the need for fertilizers.
- C. Make tolerant to abiotic stresses: This is correct. GM technology can create crops that are more resistant to environmental challenges like drought, salinity, and extreme temperatures.
- D. Develop pest resistant crops: This is correct. A common application of GM is developing crops resistant to specific pests (e.g., Bt cotton and Bt brinjal), reducing the need for chemical pesticides.
- E. Reduces post harvest loses: This is correct. Genetic modification can lead to traits like delayed ripening or improved shelf life, thereby minimizing losses after harvest.
Conclusion
Based on the analysis, statements C, D, and E accurately describe potential benefits or outcomes of genetic modifications in crops.
Therefore, the correct option is the one that includes C, D, and E.
