Explain what microevolution is? What are the three ways that variation occurs?


Microevolution is the change in allele frequencies brought about by mutation, genetic drift, gene flow, and natural selection below the species level. Over time, microevolution can translate into macroevolution, which is larger scale change above the species level.
selective breeding , mutation , & crossing over are the 3 ways variation occurs , but the main clue is that variation & microevolution arent the same .
