Question

Quizplus · Accepted Answer

A severe reduction in population size can result in a bottleneck effect, where only a small subset of the population survives and reproduces. This can greatly reduce the genetic diversity of the population.

Note: Option A, genetic drift, can also be a factor in reducing genetic diversity, but it can occur even in larger populations and is not specific to a reduction in population size. Inbreeding (B) refers to mating between closely related individuals and can lead to loss of genetic diversity over time. The founder effect (D) occurs when a small group from a larger population colonizes a new area, and the genetic makeup of the new population is influenced by the smaller sample size. Fixed (E) refers to a gene pool in which only one allele is present, and gene flow (F) refers to the transfer of genes across populations.
