Biology 2.3 Describe genetic variation and change
Key tips
- Practise writing paragraphs that express biological ideas clearly.
- You will need to communicate your knowledge on the concepts and processes relating to genetic variation and genetic change, where the gene pool is affected. Learning specific examples of animal, human, or plant populations may help you remember all the concepts.
- Use correct terminology and spelling.
- Attempt all questions.
- Understand and differentiate between key words from this standard: genetic variation, genetic biodiversity, evolution, genotype, phenotype, test cross, Punnett squares, dihybrid inheritance, crossing over, mutation, back crossing, gene pool, genetic code, species, population, gene allele, allele frequencies, founder effect, homologous, homozygous, genetic variation and change, independent assortment, segregation, recombination, meiosis, dihybrid inheritance, natural selection, migration, genetic drift, founder effect, and bottleneck effect. It may help to create a mind map showing relationships between terms as well as distinctive features.
