Short explanation

Use probability to predict the results of a single-gene cross.. Within Reproduction, this learning objective sits inside Genetic inheritance for AQA Biology 8461. Focus on using ideas such as gene, probability accurately in your explanation. A strong response should define the core idea, describe the relevant biological process, and connect it back to the question wording instead of giving a vague definition. When revising, students should aim to explain the science clearly, include precise biological vocabulary, and show how the process or structure links to the wider topic rather than listing isolated facts.

  • Misinterpreting allele frequencies: Explain that each parent contributes one allele per gene, so the probability is based on the combination of the two alleles each parent carries, not the overall allele frequency in the population.
