Genetic progress forward


DNA analyses provided by UCD university allow certification of the semen of cloned stallions: The nuclear DNA of the spermatozoa is the same as that of the original or that of the clone; the Mitochondria DNA of the semen is the same as that of the clone but is different from the MT DNA of the original. However this traceability will not apply to the offspring which will receive only nuclear DNA from the semen and MT DNA from the inseminated mare.

The result of such analyses was quite predictable, but it is worth showing them. They can also be used to verify the origin of marketed semen : It is possible to silence the rumor of semen of a clone sold as semen of the original. This for ethical and fair trade reasons. However from a genetic point of view, the offspring of a clone is not different from the offspring of the original.

here is a summary of the analyses performed on the semen of E.T. CRYOZOOTECH.

WBFSH opines on cloning

WBFSH notes that cloning serves various purposes while there's no regulation likely to fordib it. The agency express concern about ethical aspects and the resulting genetic progress but intends to remain practical :

Cloning has little chance to be banned and since all horses are to be registered because of traceability legislations, anyhow they will require a legal existence.

To be registered in a studbook is the studbook organization responsibility. Nevertheless it is recommended to clearly name clones and both their genetic and breeding donor sources. The WBFSH advises breeding organisations which would select them to consider those clones as brand new individuals to test and to disregard their models performances.

In summary : since it appears hardly difficult to ban them, the best would be to bind them to compete. And although their origins would be posted, it would be taken no account of.
