Which option avoids the common misconception in this objective for Variation and evolution, Cloning (biology only): students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell.

The correct option is Misconception avoided: Chromosome number changes in meiosis; gene variants are alleles. This matches Cloning (biology only) because students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell.. It is the only option that keeps Genes vs chromosomes separate and answers the approved learning objective in Cloning (biology only).

The correct option is Misconception avoided: Chromosome number changes in meiosis; gene variants are alleles. This matches Cloning (biology only) because students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell.. Misconception avoided: Chromosome number changes in meiosis; gene variants are alleles. This matches Cloning (biology only) because students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell. is correct because Chromosome number changes in meiosis; gene variants are alleles. The learning objective says students must describe adult cell cloning by removing the nucleus from an unfertilised egg cell, so the answer must stay inside Cloning (biology only). The alternative options are wrong because they either missing that chromosomes contain many genes., saying a chromosome codes for one protein instead of identifying a gene., or drift away from options should make scale explicit: section of dna versus long dna molecule..
