This resource provides rigorous, scaffolded practice focused exclusively on pedigree chart interpretation, a key skill in AP Biology Unit 5 (Heredity) and a frequent source of student error on the AP Exam. Students will analyze pedigree charts to determine: ✔ Autosomal dominant inheritance ✔ Autosomal recessive inheritance ✔ Sex-linked (X-linked) traits ✔ Patterns of inheritance across generations ✔ Trait predictability based on family history
