For those families who cannot accept the death of their beloved pets, cloning pets is indeed very tempting. It is seen as a continuation of life and emotion, which can make up for the regret and pain caused by losing them. However, you must know that cloning technology can only clone the same appearance and genes. However, due to the different growth environment, its personality and habits are completely different from those of the mother. It is another completely independent individual.

Korea Cloning Research Institute

In fact, Seoul National University in South Korea successfully created the world's first cloned dog, Snuppy, as early as 2005. But why didn't most people learn about the technology of cloning pets until Ms. Kim's dog cloning was spread? Because Its technology is expensive and its "quality" cannot be guaranteed, which limits the development of pet cloning. In particular, it constantly touches the moral bottom line of dog lovers, and countless dog lovers have raised flags to stop it.

Take the birth of Snuppy, for example. In order to successfully clone the mother Tai, scientists performed countless operations. More than 1,000 embryos were surgically transferred to 123 surrogate female dogs. As a result, only 3 surrogate female dogs were successfully conceived, and one of them Aborted, the other 2 were brought to term. But soon one of them died due to respiratory distress, and the other was Snuppy.

DNA is extracted from the pet to be cloned through a tissue biopsy (or within 3-5 days of death), and the tissue is cryopreserved. "Surrogate" animals produce fertilized eggs. The DNA is then removed from those eggs and the pet's preserved DNA is inserted. These altered eggs are then implanted into surrogate animals, which carry them to term, and are tested via ultrasound for pregnancy and fetal health.

In addition to causing these surrogate female dogs to suffer unnecessary pain, some clones that are not similar to their mothers or have "substandard quality" due to health problems are almost all abandoned or euthanized. Although as technology becomes more sophisticated, the number of cloned dogs is decreasing, but the uncertainty of cloning technology is too high to fully achieve "quality assurance." For example, CC, who was born at Texas A&M University in 2001, also means carbon copy. Unfortunately, CC looks completely different from the gene donor.

On the one hand, as pet owners, we can emotionally understand that love is irreplaceable, but for other dogs, what is wrong with them? In fact, if we think carefully about every bit of getting along with them, every one of them The companionship at night, every joyful smile, and every tacit interaction are the trust and love cultivated between us day and night. They are the soul that cannot be reproduced by cloning technology, and the memories that cannot be brought back by cloned pets.

Every soul should be independent and lovely. I believe that my dog ​​is unique, but I also believe that her soul is one in a million. Maybe the clone has the same little habits as her, the same little temper, and the same little hobbies as her, but he is not her after all, isn't he?

But I don’t deny that pet owners who clone their dogs have their own expressions of love. But when you are preparing to clone your dog, please also think about the surrogate female dogs and the cloned pets whose quality is not up to standard. They are also a living life like your dog.

Although clones such as Dolly the sheep, Snuppy the dog, CC the cat, and other successful clones all lived to the same age as non-clones, most of the "failures" produced in the process were abandoned or abandoned. Euthanasia. Perhaps you can use this cloning fee to save countless stray dogs that are about to die.

Note: According to a report in the United States in 2014, two clones of an 8-year-old German shepherd were found. One was healthy, and the other was euthanized after developing cleft palate and genital abnormalities.
