Introduction
Unit 5: Heredity (AP Biology)
- Core Subject Matter: The unit covers the principles of genetics, focusing on how traits are passed from parents to offspring and how they are expressed.
- Key Topics:
- Meiosis: The process of cell division that results in gametes.
- Mendelian Genetics: The fundamental laws of inheritance.
- Non-Mendelian Genetics: Inheritance patterns that do not follow simple dominant/recessive rules.
- Gene-Environment Interaction: How environmental factors influence the expression of genetic traits.
- Curriculum Alignment: The content is structured around AP Biology Big Ideas and Enduring Understandings, specifically:
- EVO (Evolution): Mechanisms of genetic variation.
- IST (Information Storage and Transmission): How genetic information is passed on and expressed.
- SYI (Systems and Interactions): How biological systems interact and change.
