Paper 2 — Inheritance, variation and evolution (overview)
Big-picture map of DNA/genes, inheritance, variation, evolution, and genetic engineering.
What’s in Inheritance, variation and evolution (Paper 2)
- DNA, genes, chromosomes
- Mitosis vs meiosis (high level)
- Inheritance (dominant/recessive)
- Variation
- Evolution + natural selection
- Genetic engineering (overview)
How it’s tested
- Genetic crosses (ratios)
- Applying selection to scenarios
- Explaining terms precisely
