Exam-style question
Try this first
Which option gives the correct cause-and-effect relationship for Reproduction, Genetic inheritance: students must explain the terms homozygous and heterozygous.
- A.Correct cause and effect: DNA is the molecule; a gene is a functional section of that molecule. This matches Genetic inheritance because students must explain the terms homozygous and heterozygous.
- B.Reversed cause: Treating DNA as if it always means one gene. This would blur DNA vs genes instead of testing Genetic inheritance.
- C.Missing link: Calling a gene a whole chromosome. This misses the objective focus on explain the terms homozygous and heterozygous.
- D.Different process: It moves into a neighbouring Unit 4.6 idea rather than Reproduction / Genetic inheritance.
