Case Study on Transgenic Animals and Plants

Case Study on Transgenic Animals and Plants

Case Study 1: Transgenic Animal – The GloFish (Genetically Modified Fluorescent Fish) 🐠

Background:
The GloFish was the first genetically modified animal to be commercially available as a pet. It was originally developed for environmental monitoring but became popular in the aquarium industry.

Genetic Modification:
Scientists inserted a fluorescent protein gene from jellyfish and sea anemones into zebra fish (Danio rerio), making them glow under UV light.

Applications:
✅ Originally designed to detect water pollution by glowing in response to toxins.
✅ Later commercialized as a pet in various colors (red, green, blue, purple).
✅ Used in biomedical research to study genetic diseases and cell development.

Regulation & Ethical Concerns:

  • The U.S. FDA (Food and Drug Administration) ruled that GloFish posed no environmental risks
  • Some countries (e.g., Canada) banned their sale due to ecological concerns.

Case Study 2: Transgenic Plant – Golden Rice 🌾

Background:
Vitamin A deficiency affects millions, causing blindness and immune deficiencies. Scientists developed Golden Rice, a genetically modified crop that produces beta-carotene (provitamin A).

Genetic Modification:
The phytoene synthase gene (psy) from daffodils and the crtI gene from soil bacteria were inserted into rice DNA to produce beta-carotene in the grains.

Applications & Benefits:
✅ Addresses malnutrition, especially in developing countries like India, Bangladesh, and the Philippines.
✅ One bowl of Golden Rice can provide 50% of daily Vitamin A needs.
✅ Helps reduce child mortality related to Vitamin A deficiency.

Challenges & Regulation:

  • Approved in the Philippines for cultivation in 2021.
  • Opposition from anti-GMO groups slowed adoption in some countries.
  • Ongoing studies to improve yield and beta-carotene retention.

Conclusion

Both GloFish and Golden Rice show how transgenic organisms solve real-world problems—whether in science, environment, or health. While Golden Rice fights malnutrition, GloFish serves in research and commercial markets. However, regulatory, ethical, and environmental factors play crucial roles in their global acceptance.
