  1. Dominance (genetics) - Wikipedia - Explains complete dominance, incomplete dominance, and codominance, providing the conceptual foundation for the ABO blood type and snapdragon examples in this chapter.

  2. X-linked inheritance - Wikipedia - Describes how genes on the X chromosome are inherited differently in males and females, including the hemizygosity that makes X-linked recessive traits more common in males.

  3. Down syndrome - Wikipedia - Overview of trisomy 21 as a case study in nondisjunction and aneuploidy, connecting the molecular error to its clinical features.

  4. Genetics: A Conceptual Approach (7th ed.) - Benjamin A. Pierce - W.H. Freeman - Pierce pioneered the side-by-side ratio-comparison table (9:3:3:1 versus 9:3:4 versus 9:7) that makes modified dihybrid ratios instantly diagnosable, a device this chapter's epistasis section directly echoes.

  5. Human Genetics: Concepts and Applications (13th ed.) - Ricki Lewis - McGraw Hill - Lewis pioneered the case-study-driven approach to teaching pedigree analysis, opening chapters with real patient and family stories that ground abstract inheritance patterns in human medical genetics rather than hypothetical organisms.
