Which option gives the correct cause-and-effect relationship for The development of understanding of genetics and evolution, The understanding of genetics (biology only): students must explain that Mendel’s breeding experiments suggested inherited units were passed to descendants unchanged.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches The understanding of genetics (biology only) because students must explain that Mendel’s breeding experiments suggested inherited units were passed to descendants unchanged.. 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 cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches The understanding of genetics (biology only) because students must explain that Mendel’s breeding experiments suggested inherited units were passed to descendants unchanged.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches The understanding of genetics (biology only) because students must explain that Mendel’s breeding experiments suggested inherited units were passed to descendants unchanged. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must explain that Mendel’s breeding experiments suggested inherited units were passed to descendants unchanged, so the answer must stay inside The understanding of genetics (biology only). 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..
