The difference between transgenic and cloned (non-transgenic) animals
|
The matter of difference |
Transgenic animals |
Cloned animals |
|
1. The entry process |
In the case of transgenic animals, the introduction of genes or DNA from outside into the sperm or egg or zygote is done. |
Cloning involves removing the nucleus of an unfertilized egg and inserting the nucleus of another animal's body cell (of the animal to be cloned) into the unfertilized egg. |
|
2. Genetic differences |
To introduce genes or DNA from outside Genetic differences arise. |
Genetic differences do not occur because the nuclear genes of 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 occur. |
Mutation or variation does not occur in this. |
|
6. External features |
Differences occur in external manifestations. |
The external manifestation is exactly the same. |
|
7. Use the process works |
Sperm, egg or single-celled zygote is used. |
Only the egg shells are used. |
