Which option correctly contrasts the named ideas for The development of understanding of genetics and evolution, The understanding of genetics (biology only): students must describe Mendel’s contribution to the development of understanding of genetics.
- A.Correct contrast: DNA can contain many genes; a gene has a specific coding role. This matches The understanding of genetics (biology only) because students must describe Mendel’s contribution to the development of understanding of genetics.
- B.Reversed contrast: Calling a gene a whole chromosome. This would blur DNA vs genes instead of testing The understanding of genetics (biology only).
- C.Over-broad contrast: Explaining protein coding without naming the gene as the relevant section of DNA. This misses the objective focus on describe Mendel’s contribution to the development of understanding of genetics.
- D.Unrelated contrast: It moves into a neighbouring Unit 4.6 idea rather than The development of understanding of genetics and evolution / The understanding of genetics (biology only).
