Preparation Tips
- • Know Mendel's two laws and how they explain inheritance patterns
- • Practice Punnett squares for monohybrid and dihybrid crosses
- • Know 3:1 ratio for monohybrid, 9:3:3:1 for dihybrid crosses
- • Understand dominant vs recessive, homozygous vs heterozygous
- • DNA structure: Double helix, sugar-phosphate backbone, complementary bases
- • Base pairing rules: A-T and G-C
- • Compare autosomal and X-linked (sex-linked) inheritance patterns
- • Analyze pedigrees to identify inheritance patterns and predict offspring
