AP Biology Full Mock Test 4: Evolution and Ecology Emphasis
AP Biology Full Mock Test 4 emphasises natural selection, Hardy-Weinberg equilibrium, phylogenetics, and ecology. Quantitative FRQ practice at full AP difficulty.
About Full Mock Test 4
Full Mock Test 4 places greatest weight on AP Biology Units 7 and 8 — Natural Selection and Ecology — while maintaining full-exam coverage across all units. These two units are rich in quantitative reasoning tasks and systems-level thinking, which Mock 4 develops through targeted AP-style question design.
Key Emphasis Areas
Hardy-Weinberg Calculations and Population Genetics
Mock 4 includes multiple Hardy-Weinberg FRQ and MCQ items. You must calculate allele frequencies (p and q), genotype frequencies (p², 2pq, q²), and predict evolutionary outcomes when equilibrium assumptions are violated. Questions will ask you to identify which evolutionary force is disrupting Hardy-Weinberg equilibrium and explain why.
Phylogenetics and Cladogram Reading
Mock 4 features phylogenetic tree interpretation questions drawn from both molecular and morphological data. You will be asked to identify common ancestors, determine which species are most closely related, and use parsimony reasoning to evaluate competing cladograms.
Population Dynamics and Ecological Energy Flow
Ecology FRQs in Mock 4 require you to interpret population growth graphs (logistic and exponential), calculate energy transfer between trophic levels using the 10% rule, and explain how removing a keystone species cascades through a food web.
