Question

question 3 (mandatory) (2 points)
allele frequency can change over time since natural selection and other processes that drive evolution are always in play. this change over time is called _________.
lethal mutation
directional selection
microevolution
biology

Explanation:

• Lethal mutation: A mutation that causes the death of an organism. It does not refer to the overall change in allele frequency over time.
• Directional selection: A type of natural selection where an extreme phenotype is favored. It is a process that can contribute to change in allele frequency but is not the term for the overall change itself.
• Microevolution: By definition, it is the change in allele frequencies in a population over generations. This matches the description in the question.
• Biology: A broad field of study that encompasses many aspects including evolution but is not the specific term for the change in allele frequency over time.

Answer:

C. Microevolution
