Which option avoids the common misconception in this objective for Variation and evolution, Variation: students must explain that variation may be caused by a combination of genes and environment.

The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Variation because students must explain that variation may be caused by a combination of genes and environment.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Variation.

The correct option is Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Variation because students must explain that variation may be caused by a combination of genes and environment.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Variation because students must explain that variation may be caused by a combination of genes and environment. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must explain that variation may be caused by a combination of genes and environment, so the answer must stay inside Variation. The alternative options are wrong because they either explaining protein coding without naming the gene as the relevant section of dna., treating dna as if it always means one gene., or drift away from do not use dna, gene, and chromosome as interchangeable answers..
