Discussion-based Labs on Genetic Engineering Ethics
Explore ethical dilemmas in genetic engineering through interactive case studies.
Discuss with your peers and consider multiple perspectives on these complex issues.
Case 1: Gene Editing in Human Embryos
A research team has successfully used CRISPR-Cas9 to edit the CCR5 gene in human embryos to make them resistant to HIV. The edited embryos were then implanted, resulting in the birth of genetically modified babies. The scientists claim this could eliminate hereditary diseases, but critics argue this crosses ethical boundaries.

Should we allow genetic modification of human embryos when the goal is disease prevention?
What are the potential long-term consequences for the modified individuals and society?
Who should decide whether this technology is used - scientists, governments, or the public?

Case 2: Gene Drives in Mosquitoes
Scientists have developed a gene drive system that could make mosquitoes resistant to carrying malaria, potentially eliminating the disease. However, this genetic modification would spread rapidly through wild populations, permanently altering the species. Environmentalists worry about unintended ecological consequences.

Do the potential benefits to human health justify permanently altering an entire species?
How should we assess potential ecological risks that might not be apparent for years?
Who should have authority to approve such releases - national governments or international bodies?
Your Position:
Case 3: Patented Genetically Modified Crops
A biotechnology company has developed drought-resistant crops through genetic modification and holds patents on both the technology and the seeds. Farmers must purchase new seeds each year rather than saving them from harvests. While this boosts yields in poor regions, it creates dependency on the company.
Should life-saving agricultural technologies be allowed to be patented and controlled by corporations?
How can we balance corporate innovation incentives with food security needs?
What alternative models could make these technologies accessible while still funding research?

Ethical Frameworks for Analysis
Key Principles:
When analyzing bioethical dilemmas, consider these frameworks:
Utilitarianism: Choose actions that maximize overall benefit
Deontological Ethics: Follow moral rules/duties regardless of consequences
Virtue Ethics: Consider what a virtuous person would do
Rights-Based: Protect fundamental human rights
Precautionary Principle: Avoid actions with potential for severe harm
Discussion Tips:
1. Identify all stakeholders and their interests
2. Separate scientific facts from values/opinions
3. Consider both short-term and long-term consequences
4. Examine potential unintended consequences
5. Discuss alternative solutions
