Common mistake
Mixing up variation with mutation
Students often think that the variation produced by sexual reproduction is the same as a mutation, and therefore describe it as a change in the DNA sequence rather than a combination of existing alleles.
Explain that variation in sexual reproduction comes from the random combination of gametes (different alleles) during fertilisation, not from new changes in the DNA sequence. Use the example of a red‑green colour‑blind parent and a normal parent producing offspring with different combinations of alleles, not new mutations.
