Worked Solution & Example Answer:A student performed a first-hand investigation in an attempt to model natural selection - HSC - SSCE Biology - Question 20 - 2012 - Paper 1
Step 1
What is the limitation of this investigation as a model for natural selection?
Answer
The correct answer is (B) Characteristics are not transmitted to successive generations.
This limitation is crucial in understanding natural selection, as for natural selection to occur, traits must be passed down through generations. In the given investigation, there's no mention that the surviving biscuits (lemon cream biscuits) influence the traits of future generations, which undermines its effectiveness as a model for natural selection.
