Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, The understanding of genetics (biology only): students must explain why the importance of Mendel’s work was not recognised until after his death.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches The understanding of genetics (biology only) because students must explain why the importance of Mendel’s work was not recognised until after his death.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in The understanding of genetics (biology only).

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches The understanding of genetics (biology only) because students must explain why the importance of Mendel’s work was not recognised until after his death.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches The understanding of genetics (biology only) because students must explain why the importance of Mendel’s work was not recognised until after his death. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain why the importance of Mendel’s work was not recognised until after his death, so the answer must stay inside The understanding of genetics (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..
