简介

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.
