Extinction is likely due to limited genetic variation
|
Detailed explanation-1: -Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift). This is because some versions of a gene can be lost due to random chance, and this is more likely to occur when populations are small.
Detailed explanation-2: -A small population of chimpanzees lives in a habitat that undergoes no changes for a long period. How will genetic drift probably affect this population? It will reduce genetic diversity. A small portion of the population that is geographically isolated from the rest of the population runs the risk of decreased.
Detailed explanation-3: -Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool. Genetic drift can also cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.
Detailed explanation-4: -The bottleneck effect occurs when a population’s size is reduced for at least one generation. Undergoing a bottleneck can greatly reduce the genetic variation in a population, leaving it more susceptible to extinction if it is unable to adapt to climactic changes or changes in resource availablility.
