The most likely reason for the development of resistance against pesticides in insects damaging a crop is
-
- random mutations
- genetic recombination
- directed mutations
- acquired heritable chages
Correct Option: A
According to Darwin resistance to pesticides has a genetic basis due to presence
of certain alleles. In the presence of pesticides, the insects devoid of the allele for resistance die while the ones having them survive. They are selected by nature.
