Answer:

genetic changes among and within populations

Explanation:

Microevolution occurs when there are changes in gene frequency within a population over a short period of time. Microevolution specifically refers to changes within a population, a population being a group of organisms that breed with each other.

hope this helps :)
Microevolution is the change in allele frequencies that occurs over time within a population.[1] This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed macroevolution which is where greater differences in the population occur.
