Answer:
The correct answer is genetic drift.
Explanation:
The phenomenon of changing the frequency of an allele in a specific population with time is known as genetic drift. The mentioned gene variation or the modification in the frequency of the allele is required to take place abruptly so that the phenomenon of genetic drift can take place. The environmental factors do not play an essential role in the phenomenon of genetic drift to take place.
The process of genetic drift occurs generally due to random sampling of organisms, it illustrates the random change in the number of gene variants within a population. When the existence of the different forms of a gene, that is, alleles, enhances or reduces by chance with time within a population, the phenomenon of genetic drift occurs. Thus, the mentioned case is an illustration of genetic drift.

Because the plant is unaffected as the worms benefit
Maybe it’s because in order the get the same apple you breed more of that apple? It would take less time than natural selection since the genes of that certain apple may not appear for a few generations. If this makes any sense let me know because I’m just as confused as you are.
