Summary
Evolution is the change in the inherited characteristics of biological populations over successive generations. Students get practice in multiple-choice questions on topics like mutations, adaptations, genetic drift, gene flow, and pre-zygotic barriers.
Mutations and randomness
Mutations are changes in DNA. The document explains how mutations are random. It asks how randomness applies to mutations. It asks how mutations affect an organism.
Adaptations and evolution
Adaptations are traits that help an organism survive. The document asks what adaptations are. It asks what evolution is. It asks what is not analogous to genetic drift.
Gene flow and barriers
Gene flow is the transfer of genetic material between populations. The document asks about the effect of increased gene flow. It asks what is not a pre-zygotic barrier.
Evolutionary time and macromolecules
Evolution happens over generations. The document asks about the order of eras. It asks where mutations occur.
Key terms
- Mutations
- Changes in DNA that can affect an organism.

- Changes in the frequency of an allele in a population over time.
- Evolution
- Change in the inherited characteristics of biological populations over successive generations.
Questions this document helps with
- What is the effect of mutations on an organism?
- How does gene flow affect populations?
