4. SELECTIVE BREEDING

5. TRANSGENESIS
• Transgenesis is the process of
introducing a gene from one
organism into the genome
of another organism.
• Aim -->> to exhibit some new traits.
• Genetic code is universal.

6. PRODUCTION OF TRANSGENIC
ANIMALS
Step 1. CONSTRUCTION OF A TRANSGENE

7. STEP 2: INTRODUCTION OF TRANSGENE
INTO THE ANIMAL
Microinjection method

8. STEM CELL METHOD

10. Transgenic cow
Transgenic sheep

11. Transgenic Goat
Transgenic Pig

12. Super Fish
Glow Fish

13. APPLICATIONS
 Agricultural Applications
• Disease resistant animals (Influenza resistant pigs).
• Improving quality and quantity of milk, meat and eggs.

14. Medical Applications
• Disease model
• Enhanced Nutritional value and pharmaceuticals
• Xenotransplantation

15. Industrial Applications
• Spider silk in milk of goat
• Wool growth in sheep is enhanced.

16. ETHICAL ISSUES
• Blurring the lines between species by creating transgenic combinations.
• Use of animals in research causes great suffering to the animals.
• There may be health risks.
• There may be long term effects on the environment when transgenic animals are
released into the field.

17. CONCLUSION
• Transgenic technology is a field that is
under constant evolution.
• With proper research and careful use
the transgenic animals can go a long
way in solving several problems.
