The Relatively Short-Term Changes in Allele Frequencies Within a Population

Question

The relatively short-term changes in allele frequencies within a population is
A) fitness.
B) adaptation.
C) microevolution.
D) convergent evolution.
E) natural selection.

Accepted Answer

Microevolution refers to the changes in the frequency of alleles within a population over a short period of time, usually within a few generations. This can be caused by various factors, such as genetic drift, gene flow, and natural selection. Fitness refers to the ability of an individual to survive and reproduce in its environment, whereas adaptation refers to the accumulation of changes over time that increase the survival and reproduction of a species in a particular environment. Convergent evolution refers to the development of similar structures or adaptations in unrelated species that are exposed to similar environmental pressures. Natural selection is the process by which nature selects individuals with favorable traits that increase their chances of survival and reproduction.
