| Pitfall | How to Avoid It | |---------|-----------------| | | After solving a problem, ask why the ratio appears (e.g., independent assortment → 9:3:3:1). | | Confusing “dominant” with “more common” | Dominance refers to phenotype expression, not frequency. Check allele frequencies separately. | | Mixing up genotype vs. phenotype notation | Use uppercase = dominant allele , lowercase = recessive allele for genotype; draw actual trait pictures for phenotype. | | Skipping the “why” of Hardy‑Weinberg | Memorize the equation, then rehearse the five assumptions (no selection, mutation, migration, drift, random mating). | | Assuming every gene follows Mendel | Remember linked genes , polygenic traits , and epistasis break the simple ratios. | | Over‑reliance on one source | Cross‑check tricky concepts (e.g., RNA interference) with a video or article to ensure you haven’t mis‑interpreted the PDF’s wording. |
