The Difference Between Transgenic and Cloned (Non-Transgenic) Animals
The Matter of Difference
| Feature |
Transgenic Animals |
Cloned Animals |
| 1. The Entry Process |
Introduction of genes or DNA from outside into the sperm, egg, or zygote is performed. |
Cloning involves removing the nucleus of an unfertilized egg and inserting the nucleus of another animal’s body cell (the animal to be cloned) into the unfertilized egg. |
| 2. Genetic Differences |
Genetic differences arise due to the introduction of foreign genes or DNA. |
Genetic differences do not occur because the nuclear genes of the two animals do not combine. |
| 3. Disclosure of Features |
A combination of special features occurs. |
No special features are revealed. |
| 4. Genomic Differences |
Genomic differences arise. |
The genomic structure is exactly the same. |
| 5. Mutation or Variation |
Mutations may occur. |
Mutation or variation does not occur. |
| 6. External Features |
Differences occur in external manifestations. |
The external manifestation is exactly the same. |
| 7. Use of Process |
Sperm, egg, or single-celled zygote is used. |
Only the eggs are used. |
