The most likely reason for the development of resistence against pesticides in insects damaging a crop is

Options

A. Random mutations
B. gemetic recombinations
C. directed mutations
D. acqurired heritable changes

Answer

A

Explanation

The most likely reason for the development of resistance against pesticides in insect damaging a crop is random mutations, because environmental stress, i.e. pesticides does not cause direct changes in genome m instead, it simply selects rather persisting mutations which result in phenotypes that are better adapted to the new environment in certain pesticides.
