What is genetic drift?

• A process where organisms adapt to their environment

• A random change in allele (trait) frequencies in a population

• A way to increase genetic diversity

• A method of selecting the best traits for survival

How does genetic drift differ from natural selection?

• Natural selection does not affect allele (trait) frequencies

• Genetic drift is a deliberate process

• Genetic drift is random

• Natural selection is random

What is the bottleneck effect?

• A way to select the fittest organisms

• A method of increasing genetic diversity

• A random event that reduces population size

• A process where a population grows rapidly

What example is used to explain the bottleneck effect?

• A candy jar

• A forest fire

• A scooter ride

• A Halloween bucket

What is the founder effect?

• A process where a new population is started by a few individuals

• A method of selecting the best traits for survival

• A random event that reduces population size

• A way to increase genetic diversity

What example is used to explain the founder effect?

• Seeds dispersed by wind

• A scooter ride

• A candy jar

• A forest fire

What can genetic drift lead to in a population?

• Increased adaptation

• Increased population size

• Random changes in trait (allele) frequencies

• Decreased genetic diversity

Which population size is more vulnerable to genetic drift?

• Small population

• Large population

• Both are equally vulnerable

• Neither is vulnerable

What happens to the allele frequencies after a bottleneck event?

• They remain the same

• They become more diverse

• They become more uniform

• They change randomly depending on the individuals that survive
