Which option best identifies the exact concept boundary for Variation and evolution, Selective breeding: students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.

The correct option is Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Selective breeding.

The correct option is Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.. Definition boundary: DNA can contain many genes; a gene has a specific coding role. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations. is correct because DNA can contain many genes; a gene has a specific coding role. The learning objective says students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations, 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..
