Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, Speciation (biology only): students must describe the work of Darwin and Wallace in developing the theory of evolution by natural selection.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Speciation (biology only) because students must describe the work of Darwin and Wallace in developing the theory of evolution by natural selection.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Speciation (biology only).

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Speciation (biology only) because students must describe the work of Darwin and Wallace in developing the theory of evolution by natural selection.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Speciation (biology only) because students must describe the work of Darwin and Wallace in developing the theory of evolution by natural selection. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must describe the work of Darwin and Wallace in developing the theory of evolution by natural selection, so the answer must stay inside Speciation (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..
