Does the animal I produce using cloning technology have the same DNA as the genetic donor?

September 8, 2020

In the cloning process, the animal produced using cloning technology will carry a nuclear genome (DNA) that is a genetic match to the genetic donor animal. In other words, nuclear genotypes (as produced for breed registry DNA genotyping) of the cloned animal will be the same as the genetic donor that provided the tissue sample to produce the cell line or Genetic Preservation. If you are cloning a breed that utilizes genomic evaluations, the genomics of the cloned animal will also be the same as the genetic donor.

How does the cloning process work?

September 8, 2020

The word “cloning” is simply a term to describe Somatic Cell Nuclear Transfer (SCNT). Once cells are produced from the tissue sample provided by a genetic donor, they are combined with an enucleated oocyte (unfertile egg with the nucleus removed) and fused together using a process called electrofusion. The resulting embryos are cultured and transferred into recipient mothers within one week, with variation per species. “Dolly the Sheep” was the first mammal to be produced using SCNT cloning technology more than 20 years ago.

How can I preserve the genetics on my most elite animal indefinitely?

September 8, 2020

An elite animal, the genetic donor, provides a tissue sample that will be cultured into a cell line or Genetic Preservation (GP). These cells will be cryopreserved or frozen until they are used in the cloning process at a later date. The tissue sample may come from the ear or tail of the genetic donor animal. An economical alternative, an Express Tissue Bank (ETB), is provided for those producers who wish to preserve a large amount of samples or simply are not certain they will move forward with the cloning process. In this program, the tissue sample is frozen intact.…

Why do livestock breeders such as myself, use cloning technology?

September 8, 2020

Through the cloning process, progressive producers can duplicate the animals that contribute the most value in their herds and forward their goals to produce more efficient, healthier animals, and better quality food products. The influence of these animals, through breeding, can help create a more consistent supply of tender, flavorful beef, for example. Another example of a cloning application is in the case of an animal lost early in its breeding career due to death or injury; perhaps even before the value of its genetics were fully discovered. Cloning technology can also help extend an elite animal’s genetic influence to…
