AP Biology: Heredity

~8%–11% of multiple-choice exam weight

Ready When You Are

Select a course and unit, then generate a question.

Students often underestimate Heredity because it appears early in the syllabus, but AP questions here test application, not memorized definitions alone.

Mendelian genetics, inheritance patterns, and chromosomal basis of heredity. On the AP Biology exam, items from Heredity often ask you to connect structure to function or explain experimental results rather than recall isolated terms.

College Board topic statements for this unit include Mendelian crosses, probability in inheritance; Complex inheritance: linked genes, sex linkage, epistasis; and Chromosomal abnormalities and pedigree analysis.

On the AP Biology exam, Heredity is weighted at roughly 8%–11% of the multiple-choice section. That is enough to matter on score day even if your class spent only a few weeks here—especially when questions combine this unit with later material.

Time pressure makes Heredity tempting to rush—especially when numbers or dates appear in every option. Slow down enough to identify what the question is actually asking before eliminating distractors.

Connect new terms to one anchor example you already understand. Isolated definitions fade; anchored ones stick through May.

End each Heredity study block by writing one exam-style prompt you could ask a classmate. If you can write it, you probably understand what the College Board is probing.
