Question

Most likely reason for development of resistance in insects against pesticides is

• A. genetic recombination
• B. Acquired heritable changes
• C. random mutations
• D. directed mutations.

Answer 1

The correct option is C random mutations

Pesticides are generally used to kill the insect which harms the plant. The pesticides used over time on insect kill them but after a certain amount of time, the insects become resistant to the pesticides used. Random mutation plays a role in this. The changes in DNA occur which can lead to the better survival of the organism in a severe environment.

So, the correct option is 'random mutations'
