Evidence for Evolution and Classification Systems

Explain the molecular structure of DNA, define the genome, and evaluate the medical significance of genomic research.

Master genetic terminology, predict phenotypic and genotypic outcomes using Punnett squares, and analyse sex determination and family pedigrees.

Distinguish between continuous and discontinuous variation, analyse the origin and impact of mutations, and calculate statistical measures of variation.

Explain how natural selection drives evolution, contrast evolutionary theories, and explain the mechanism of speciation.

Evaluate evidence for evolution from fossils and bacterial resistance, and examine modern developments in biological classification.

Explain selective breeding and genetic modification techniques, and evaluate the ethical, economic, and practical impacts of modern biotechnology.

Apply ratios, probabilities, pedigree charts, and graphical data analysis to solve GCSE genetics and evolution problems.
