Big Ideas
- Genetic variations in organisms arise from several mechanisms, including meiosis, DNA replication errors, and environmental influences.
- Understanding the causes of genetic variation is critical to explaining how traits are inherited and why individuals differ.
Essential Questions
- How do new genetic variations arise in organisms?
- What roles do meiosis, replication errors, and environmental factors play in generating genetic differences?
- How does inheritable variation affect populations over time?
- How can evidence be used to support claims about the sources of genetic variation?
- Why is understanding genetic variation important for explaining inheritance and evolution?
