Gene editing is advancing rapidly, led by startups and unregulated labs, risking deep global inequality.

Genetic Optimisation

• Definition: Genetic Optimisation refers to the use of genetic screening and selection technologies to choose embryos based on preferred health or personality traits before implantation. It opens the door to “designer babies”.
• Technological Leap: Once confined to science fiction, genetic optimisation is now a reality in modern fertility clinics. 
  • Cutting-edge startups are reshaping how parents plan their children’s future.
• Nucleus Embryo: Launched by Nucleus Genomics, the ‘Nucleus Embryo’ platform allows screening of up to 20 embryos. It analyses more than 900 conditions and traits, moving beyond just disease prevention.
• Screening: Traits now include Polygenic risk scores for diseases (e.g., cancer, Alzheimer’s) and personality-related factors like intelligence, anxiety, and height
• Ethical and Societal Implications: This development raises critical questions about Moral boundaries in reproductive choice.
  • Social inequality due to access to such technologies The shift from curing disease to customising humans

Working of Embryo Screening

• IVF Process: In In-Vitro Fertilisation (IVF), doctors typically generate around 15–20 embryos per couple.  Traditionally, selection of embryos for implantation was based on doctors’ intuition or visual quality.
• Lack of Genetic Insight: The embryo with the best visible quality was chosen — not necessarily the healthiest. This method lacked scientific precision, often leaving outcomes to chance.
• Genetic Testing: Now, embryos undergo DNA-level testing — a process known as embryo genotyping. This allows for the prediction of both disease risks and non-disease traits.
• Scientific Analogy: Just like a blood test predicts health risks, embryo DNA testing reveals future genetic predispositions. Parents can now make informed decisions based on genomic data, not just morphology.
• Predictive Genetics in Action: Embryos are screened for Genetic diseases (e.g., thalassemia, cancer), traits like intelligence, anxiety, or height. This represents a major shift towards genetic optimisation.

Polygenic Scoring

• Genetic Analysis: Modern screening is no longer limited to monogenic disorders like cystic fibrosis or Huntington’s disease. Instead, it now focuses on polygenic traits  influenced by multiple genes.
• Polygenic: Each gene contributes a tiny amount of risk or advantage. Alone, each variant means little  but together, they shape outcomes like intelligence, height, or disease susceptibility.
• Composite Risk Calculation: Machine learning algorithms analyse hundreds or thousands of gene variants. They generate a Polygenic Risk Score (PRS) — e.g., 82/100 for cancer or IQ prediction.
• Applications: Parents can now compare embryos based on cancer risk, likelihood of depression, cognitive potential, etc. This enables predictive embryo selection, not just screening for disease.
• Ethical Frontier: While promising for disease prevention, PRS raises deep moral concerns about trait selection and designer babies.

Rise of Designer Babies

• Reality: What was once science fiction is now technological fact.  Genetic tools allow parents to select traits for health, appearance, and even intelligence.
• Customisation: Choosing eye colour, height, or emotional temperament may soon resemble picking outfits. This marks a shift from natural inheritance to genetic curation.
• Inequality: While it promises disease-free children, it could also widen the rich-poor gap. The wealthy may afford “perfect” babies, leaving others behind.
• Urgency for Regulation: Without strong bioethical frameworks, science could outpace ethics. The balance between scientific possibility and moral responsibility is critical.

Startups in the Genetic Revolution

• Private Sector Push: Biotech startups like Orchid now offer full-genome sequencing of embryos. This service, once exclusive to the ultra-rich, is becoming accessible to the middle class.
• Base Editing: Advances like base editing allow scientists to rewrite individual DNA letters. This is a leap from simply decoding genes to actively editing life itself.
• Investors: Prominent investors, like the CEO of Coinbase, are funding embryo editing ventures. These efforts aim to push from selection to full-scale genetic engineering.
• Shift in Power: The future of human biology is being shaped not in parliaments, but in labs and boardrooms. This shift raises concerns about regulation, equity, and long-term societal impact.

Global Threat

• China’s Bold Moves: Chinese labs are editing genes to enhance traits like intelligence and strength. The goal is  creating “superhumans” through biotechnology.
• Minimal Regulation: Many Chinese facilities operate without strict ethical restrictions. This raises concerns about human rights and scientific responsibility.
• Global fall out risk: If even one country crosses ethical lines, the effects ripple worldwide. A bioethics crisis has begun threatening global trust and cooperation.

Issues Associated with India

• Ultrasound Misuse: Ultrasound machines meant for foetal health were widely used for sex-selection.
  • Result: Skewed sex ratio — 910 girls per 1000 boys in Haryana even today.
• Entrenching Biases: If gene editing enables preferences for fair skin or tall male children,casteism, colourism, and gender bias could become genetically entrenched.
• Urgent Need: India’s past misuse of reproductive tech shows why urgent regulation is essential. Without ethical safeguards, genetic tools may deepen social inequalities.

India’s Moral Message

• Spiritual Legacy: India is rooted in spiritual depth and ethical traditions. Concepts like karma and respect for human dignity shape public ethos
• Vaccine Equity: India led globally by ensuring vaccine access for developing nations. It demonstrated that science can serve humanity, not just profit.
• Beyond Profit: India can offer a “third way” balancing compassion with innovation. A model distinct from Silicon Valley’s profit focus or China’s state-driven ambition.

Impact of Gene Editing

• Agriculture and Environment: Gene editing is also transforming crops and species, not just humans. CRISPR enables the creation of drought-resistant crops, improving food security.
• Risks to Small Farmers: Most gene-edited seeds are patented by big corporations,potentially marginalising small and traditional farmers.
• Elimination: Gene drives can eliminate malaria by eradicating mosquito populations. But accidental release could cause ecological collapse, threatening biodiversity — e.g., Sundarbans.

Way Forward

• Accelerate Ethical Research: Promote collaboration between universities, public institutions, and ethical entrepreneurs. 
  • Focus: Gene editing, synthetic biology, and bioethics rooted in Indian values.
• Ensure Equitable Access: Build on India’s success in generic drugs.  Provide public funding and subsidies so rural and tribal areas access CRISPR therapies (e.g., for thalassemia).
• Reform Regulatory Framework: India’s biotech laws are outdated  predating CRISPR.  Need a new regulatory structure, co-created with scientists, civil society, and the public.It must define limits, ensure oversight, and build public trust.
• Lead Global Norms: India must push for a ban on non-medical trait selection, regulation of gene drives, and greater transparency and accountability, setting a global ethical benchmark—just as it once led the way in ensuring access to affordable vaccines.
• Rejection: India must reject the extremes of Silicon Valley’s profit-driven science and China’s state-controlled innovation, and instead chart a “third path” one that is rooted in spiritual values, guided by ethical reasoning, and committed to serving the many, not the elite.

Conclusion

The global future of genetic science must balance progress with principled restraint.  India is uniquely placed to guide this revolution but time is short.  It must act now to ensure technology uplifts humanity, not divides it.
