Final answer:
Bottleneck busting tactics refer to the bottleneck effect, where a natural disaster dramatically alters a population's genetic structure by randomly eliminating many individuals, leaving the survivors' genetic makeup as the new genetic basis of the population.
Step-by-step explanation:
The results of bottleneck busting tactics during natural disasters can dramatically alter a population's genetic structure. This happens because a significant portion of the genome is wiped out suddenly, such as after an earthquake or hurricane. The genetic structure of the surviving individuals then becomes representative of the entire population's genetic structure, which may be significantly different from that of the pre-disaster population. This is referred to as the bottleneck effect.
Natural events amplify genetic drift through the bottleneck effect. If the allele frequencies in the survivors are different by chance, these differences become exaggerated in the new population. Over time, this leads to the potential emergence of new traits and a loss of genetic diversity. In contrast, the founder effect occurs when a few individuals start a new population with allele frequencies possibly differing from the original population.
