What is a true statement about microevolution and macroevolution?
Microevolution refers to small-scale changes in gene frequencies within a population over generations, while macroevolution involves large-scale evolutionary changes that lead to the formation of new species. Both processes are driven by genetic variation, natural selection, and other evolutionary mechanisms. Microevolution is the basis for macroevolution, as accumulated small changes can eventually result in the divergence of distinct species.
Can microevolution lead to macroevolution?
Yes, microevolution, which consists of small changes in allele frequencies within a population, can accumulate over time to bring about macroevolutionary changes such as the emergence of new species. This process occurs through mechanisms like genetic drift, natural selection, and gene flow.
Which is not part of macroevolution?
Microevolution is not part of macroevolution. Microevolution involves small-scale changes within a species over a shorter period of time, while macroevolution involves larger scale changes that lead to the formation of new species over a longer period of time.
What is true about microevolution?
Microevolution refers to small-scale changes in allele frequencies within a population over a short period of time. It can be observed through adaptations like changes in coloration or size. These changes do not lead to the formation of new species but can result in populations becoming better suited to their environment.
What is evolution in the smallest scale called?
Microevolution.

When microevolution occurs over many generations as inherited characteristics lead changes in populations what has occurred?
Descent with modification
True or false that random mating leads to microevolution?
False. Random mating itself does not lead to microevolution; it typically maintains genetic variation within a population. Microevolution occurs due to factors such as natural selection, genetic drift, mutation, and gene flow, which can change allele frequencies over time. Random mating helps ensure that these processes can occur without the influence of selective mating patterns.

What is the role of population genetics in the study of microevolution?
Microevolution can be studied by observing changes in the numbers and types of alleles, or genetics, in populations.
