Which option gives the correct cause-and-effect relationship 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 Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. 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 Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Selective breeding because students must explain that selected parents are bred, then offspring with desired characteristics are bred over many generations.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. 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 is the molecule; a gene is a functional section of that molecule. 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 treating dna as if it always means one gene., calling a gene a whole chromosome., or drift away from when asking about dna, test molecular structure, base sequence, nucleotides, or genetic information storage..
