Some of the characteristics of Bt cotton are:
Correct answer: D. High yield and resistance to bollworms.
- A. Long fibre and resistance to aphids
- B. Medium yield, long fibre and resistance to beetle pests
- C. High yield and production of toxic protein crystals which kill dipteran pests
- D. High yield and resistance to bollworms.
Explanation
Bt toxin genes were isolated from Bacillus thuringiensis and incorporated into the cotton plant. The genetically modified crop is called Bt cotton. Bt cotton has the following useful characteristics: pest resistance, herbicide tolerance, high-yield, and resistance to bollworm infestation.
