What Does a Sudden Reduction in Population Size Generally Result

Question

What does a sudden reduction in population size generally result in?
A) extinction
B) mutation
C) speciation
D) genetic drift

Accepted Answer

A sudden reduction in population size generally results in genetic drift, which is a change in the frequency of existing alleles in a population due to random sampling of organisms. This can lead to a loss of genetic variation and potentially influence the evolutionary path of the population.
