Key terms
- environment: environment is a curriculum-aligned term linked to the learning objective: Explain that variation may be caused by a combination of genes and environment..
- variation: In Variation, variation means variation is a curriculum-aligned term linked to the learning objective: Explain that variation may be caused by a combination of genes and environment. This matters in Variation and evolution because it supports the learning objective to explain that variation may be caused by a combination of genes and environment. Use variation only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
