The Difference Between Transgenic and Cloned (Non-Transgenic) Animals

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.
