Which option avoids the common misconception in this objective for Variation and evolution, Variation: students must state that there is usually extensive genetic variation within a population of a species.

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 state that there is usually extensive genetic variation within a population of a species.. 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 state that there is usually extensive genetic variation within a population of a species.. Misconception avoided: A DNA base sequence is the storage format; a gene is the named instruction unit. This matches Variation because students must state that there is usually extensive genetic variation within a population of a species. is correct because A DNA base sequence is the storage format; a gene is the named instruction unit. The learning objective says students must state that there is usually extensive genetic variation within a population of a species, 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..
