Question

Some of the characteristics of Bt cotton are:

• A. Long fiber and resistance to aphids
• B. Medium yield, long fiber 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

Answer 1

The correct option is D High yield and resistance to bollworms

Bt toxin genes were isolated from Bacillus thuringiensis and incorporated into the cotton plant to form a genetically modified crop called Bt cotton. This variety was highly resistant to bollworms and thus produced a higher yield.
Hence the correct statement with regards to BT cotton is "High yield and resistance to bollworms".
