4.Principles of Inheritance and Variation
normal
The most likely reason for the development of resistance against pesticides in insect damaging a crop is
A
Random mutations
B
Genetic recombination
C
Directed mutations
D
Acquired heritable changes
Solution
The environmental stress (as pesticides) does not cause the direct changes in genome, instead, it simply selects rather persisting mutations, which result in phenotypes that are better adapted to the new environment ($e.g.,$ certain pesticides).
