Question 20
Which is the strongest final answer to the inquiry question, "Does artificial manipulation of DNA have the potential to change populations forever?"
A No, because biotechnology never affects populations in the long term
B Yes, potentially, but long-term change depends on scientific capability plus broad social uptake over time
C Yes, automatically, because any working technology spreads everywhere
D The question cannot be answered at all
Section B - Extended Response (20 marks)
IQ1 - Mutation and Gene Pools
Question 21
Evaluate the roles of mutation, gene flow and genetic drift in changing the gene pool of a population.
5 marks
Mutation creates new alleles, so it is the source of genuine genetic novelty [1]. Gene flow changes a gene pool by moving existing alleles between populations [1]. Genetic drift changes allele frequencies by chance and can be especially strong in small populations [1]. Their relative importance depends on the context: mutation adds novelty, gene flow transfers alleles, and drift can rapidly alter frequencies even without adaptive benefit [1]. Therefore all three matter, but in different ways and under different population conditions [1].
IQ2 - Biotechnology and Biodiversity
Question 22
Evaluate the benefits of biotechnology in agriculture and medicine, while accounting for biodiversity trade-offs in agriculture.
5 marks
Biotechnology can benefit agriculture by improving yield, resistance and sometimes nutritional quality [1]. It can benefit medicine through production of useful biological products such as insulin and other targeted applications [1]. However, agricultural systems may face biodiversity trade-offs if reliance on a narrow range of genotypes increases [1]. This can reduce genetic diversity and resilience even when productivity rises [1]. Therefore biotechnology can be highly beneficial, but agricultural benefit should be judged alongside biodiversity rather than by productivity alone [1].
IQ3 - Genetic Technologies and Population Change
Question 23
Compare reproductive technologies, cloning and recombinant DNA technology in terms of what each changes and how each can influence future genetic outcomes.
5 marks
Reproductive technologies such as artificial insemination and artificial pollination mainly control which gametes combine, so they guide inheritance without usually changing DNA sequence directly [1]. Cloning copies genetic material, but whole-organism cloning aims to preserve a genotype while gene cloning copies selected DNA sequences [1]. Recombinant DNA technology works more directly by inserting selected DNA into vectors and host cells [1]. Therefore reproductive technologies redirect allele combination, cloning copies genetic material at different levels, and recombinant DNA can introduce selected DNA more directly [1]. Each can influence future genetic outcomes, but by different mechanisms [1].
Question 24
Evaluate whether artificial manipulation of DNA has the potential to change populations forever.
5 marks
Artificial manipulation of DNA can potentially change populations over long time scales because it can alter which traits are introduced, copied or spread through future generations [1]. Technologies such as recombinant DNA and transgenics show that genetic outcomes can be directed more directly than by ordinary breeding alone [1]. However, long-term population change is not automatic [1]. Real impact depends on whether technologies are affordable, regulated, accepted and widely adopted across communities and over time [1]. Therefore artificial manipulation of DNA has the potential to change populations forever, but only when biological capability is matched by broad and lasting social uptake [1].
