Question

The most likely reason for the development of resistance against pesticides in insect damaging a crop is

• A. Genetic recombinations
• B. Random mutations
• C. Acquired heritable change
• D. Directed mutations

Answer 1

The correct option is B Random mutations

The environmental stress (as pesticides) does not cause or direct changes in the genome, instead, it enters through the food chain and simply select rather persisting mutation which results in the phenotype that is better adapted to the new environment like certain pesticides.
