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.
Only the strongest animals survive
As per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.
<h3>What is Genetic material?</h3>
Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.
In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.
These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.
Therefore, as per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.
