Which option correctly contrasts the named ideas for Variation and evolution, Selective breeding: students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Selective breeding because students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Selective breeding.

The correct option is Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Selective breeding because students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics.. Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches Selective breeding because students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must describe selective breeding as humans breeding plants and animals for particular genetic characteristics, so the answer must stay inside Selective breeding. 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..
