Which option correctly contrasts the named ideas for Variation and evolution, Variation: students must describe how the genome and interaction with the environment influence phenotype.
- A.Correct contrast: Mitosis produces identical cells; meiosis produces genetically different gametes. This matches Variation because students must describe how the genome and interaction with the environment influence phenotype.
- B.Reversed contrast: Claiming mitosis produces gametes. This would blur Mitosis vs meiosis instead of testing Variation.
- C.Over-broad contrast: Forgetting chromosome number is maintained in mitosis but halved in meiosis. This misses the objective focus on describe how the genome and interaction with the environment influence phenotype.
- D.Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than Variation and evolution / Variation.
