Final answer:
Microevolution refers to the relatively short-term changes in allele frequencies within a species or population.
Step-by-step explanation:
Microevolution refers to the small-scale changes in the genetic makeup of a population over a short period of time, often within a few generations. It is one of the levels of evolution that deals with the changes in allele frequencies and traits within a population. Microevolutionary processes are observed and studied within populations and can lead to variations in traits among individuals.
Microevolution refers to the relatively short-term changes in allele frequencies within a species or population. It is the process by which small changes occur within a population over generations. These changes can be caused by various evolutionary forces such as genetic drift, gene flow, mutation, nonrandom mating, and environmental variances.
