Random mutation

Vedclass · Answer

(A) The development of resistance in pests against chemical pesticides or biological control agents is primarily due to $Random 	ext{ } mutation$. When a large population of pests is exposed to a control agent, most individuals die. However, due to random mutations occurring in the population, some individuals may possess a genetic variation that confers resistance. These resistant individuals survive and reproduce, passing the resistance gene to their offspring, leading to a population that is resistant to the agent.
