Which option correctly contrasts the named ideas for Variation and evolution, Variation: students must define variation as differences in characteristics between individuals in a population.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Variation because students must define variation as differences in characteristics between individuals in a population.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Variation.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Variation because students must define variation as differences in characteristics between individuals in a population.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Variation because students must define variation as differences in characteristics between individuals in a population. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must define variation as differences in characteristics between individuals in a population, so the answer must stay inside Variation. The alternative options are wrong because they either calling a gene a whole chromosome., explaining protein coding without naming the gene as the relevant section of dna., or drift away from when asking about genes, test a section of dna, protein coding, alleles, or inherited characteristics..
