Correct option is D
The correct answer is:option (d) Bt Cotton.
Explanation of the Answer:
Bt Cotton
- Approved in India: In 2002, Bt cotton became the first genetically modified (GM) crop to be approved for commercial cultivation in India.
- It is genetically modified to include a gene from the bacterium Bacillus thuringiensis (Bt), which provides resistance to bollworms, a major pest affecting cotton crops.
- Bt cotton has significantly improved cotton yield in India but has also sparked debates regarding farmer dependency on biotech companies.
What are Genetically Modified (GM) Crops?
Definition:
Genetically modified (GM) crops are plants whose DNA has been altered using genetic engineering techniques to give them desirable traits, such as pest resistance, herbicide tolerance, or improved nutritional content.Key Features of GM Crops:
- Pest Resistance: Crops like Bt cotton contain genes that make them resistant to pests like bollworms.
- Herbicide Tolerance: Some GM crops are engineered to tolerate specific herbicides, reducing the need for manual weeding.
- Improved Yield and Quality: Genetic modifications can lead to higher yields and better nutritional content.
Examples of GM Crops Worldwide:
- Bt Corn: Resistant to the European corn borer pest.
- Golden Rice: Enriched with Vitamin A.
- Herbicide-Resistant Soybean: Engineered to survive applications of herbicides.
