include: - What effect does increasing mutation rate have on genetic diversity? Answer: It
increases genetic diversity by introducing new genetic variants into the population. - How
does mutation influence evolution? Answer: Mutations create new alleles, providing raw
material for natural selection to act upon. 2. Natural Selection and Its Role The Gizmo
simulates different environmental conditions to show how certain traits become more
common over time. Sample questions and answers: - Which traits are favored in a dark
environment? Answer: Traits that confer camouflage or better adaptation to the dark
environment become more prevalent. - What happens to the frequency of a beneficial
trait over generations? Answer: Its frequency increases as individuals with that trait are
more likely to survive and reproduce. 3. Population Dynamics and Evolution The Gizmo
tracks changes in allele frequencies over multiple generations. Key questions and
answers: - What is genetic drift? Answer: Random changes in allele frequencies that occur
in small populations, which can lead to significant evolutionary changes. - How does
population size affect evolution? Answer: Smaller populations are more susceptible to
genetic drift, leading to faster genetic changes, while larger populations tend to maintain
genetic stability. --- Tips for Mastering the Evolution Mutation Selection Gizmo 1.
