Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, Theory of evolution (biology only): students must explain that individuals in a species show a wide range of variation for a characteristic.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that individuals in a species show a wide range of variation for a characteristic.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Theory of evolution (biology only).

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that individuals in a species show a wide range of variation for a characteristic.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Theory of evolution (biology only) because students must explain that individuals in a species show a wide range of variation for a characteristic. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain that individuals in a species show a wide range of variation for a characteristic, so the answer must stay inside Theory of evolution (biology only). 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..
