Which option gives the correct cause-and-effect relationship for The development of understanding of genetics and evolution, Speciation (biology only): students must describe Wallace’s work gathering evidence worldwide, including warning colouration and speciation.

The correct option is Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Speciation (biology only) because students must describe Wallace’s work gathering evidence worldwide, including warning colouration and speciation.. It is the only option that keeps DNA vs genes separate and answers the approved learning objective in Speciation (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 Speciation (biology only) because students must describe Wallace’s work gathering evidence worldwide, including warning colouration and speciation.. Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Speciation (biology only) because students must describe Wallace’s work gathering evidence worldwide, including warning colouration and speciation. is correct because DNA is the molecule; a gene is a functional section of that molecule. The learning objective says students must describe Wallace’s work gathering evidence worldwide, including warning colouration and speciation, so the answer must stay inside Speciation (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..
