A: Due to bottleneck effect, among the survivors, certain alleles may ...
And Reason are true and Reason is the correct explanation of the Assertion.
The bottleneck effect refers to a sharp reduction in the size of a population due to a random event, such as a natural disaster or disease outbreak. This reduction in population size can lead to changes in the genetic makeup of the population.
Assertion A states that due to the bottleneck effect, certain alleles may become over-represented, some may become underrepresented, and some may be eliminated altogether. This is because the random event that caused the bottleneck may have affected certain individuals or groups of individuals more than others, leading to a change in the frequency of different alleles within the population.
Reason R states that the path of extinction of a species cannot be reversed due to the bottleneck effect. This is because the bottleneck effect typically reduces the genetic diversity within a population, making it more vulnerable to further environmental changes or challenges. In other words, the reduced genetic diversity can limit the ability of a population to adapt and survive in changing conditions, increasing the risk of extinction.
In this case, both Assertion A and Reason R are true, and Reason R is the correct explanation of Assertion A. The bottleneck effect can lead to changes in allele frequencies within a population, and the reduced genetic diversity caused by the bottleneck can increase the risk of extinction for a species.
