Answer:
Option D, The DDT killed susceptible flies. The few that were already naturally resistant survived and passed this resistance on to their offspring.
Explanation:
When DDT was sprayed for the first time, some of the house flies which were not capable enough to withstand the adverse effects of DDT , eventually died. And the butterflies that survived through this, were having a natural resistance against DDT. Now, with time these DDT resistant houseflies mated and produced offspring that had genetic trait of resisting DDT by birth. This is the reason, why houseflies after ten years were as abundant as ten years back when the control program was started.
Option D is correct
T<span>he least likely to be a source of genetic variation among living organisms is D. asexual reproduction. Asexual reproduction is a kind of reproduction that does not include fertilization process of two gametes: female and male but only includes parts of plants or cells. In this case, variation is minimized</span>
