Q52.
Consider the following techniques/phenomena: 1. Budding and grafting in fruit plants. 2. Cytoplasmic male sterility. 3. Gene silencing. Which of the above is/are used to create transgenic crops?
Answer
B
Explanation
All three methods are used for transgenic crops directly or indirectly. However, Cytoplasmic male sterility and Gene silencing are technologies specifically designed for this purpose, making option b more appropriate. Budding and grafting are general horticultural techniques not specific to transgenics.
