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 option is (B) Characteristics are not transmitted to successive generations.
In natural selection, heritable characteristics are passed from one generation to the next. In this investigation, the biscuits are not capable of passing on traits to future generations, thus limiting its effectiveness as a model for natural selection.
