Which option gives the correct cause-and-effect relationship for Variation and evolution, Selective breeding: students must describe choosing parents with desired characteristics from a mixed population.

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 describe choosing parents with desired characteristics from a mixed population.. 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.

Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Selective breeding because students must describe choosing parents with desired characteristics from a mixed population. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must describe choosing parents with desired characteristics from a mixed population, 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..
