Cloning refers to a variety of processes that can be used to create genetically identical versions of a biological organism. A clone is something that has been replicated that has the same genetic structure as the original. Researchers have cloned various biological products, including chromosomes, cells, tissues, and even whole animals like sheep.

Cloning is a vision of the future for others but a bridge too far for others. However, there should be no question that this technology would have significant implications for the future, whether for good or worse, no one knows yet. While cloned steaks are now available in supermarkets, cloning is not a new concept. Since 1885, when Hans Adolf Edward Dreisch cloned a sea urchin, animals have been cloned. Cloning may be the only way to save certain endangered species.

Here are 5 of the most famous cloned organisms in history!

CC (Copycat) the Cloned Cat

CC was the first cloned puppy, a brown tabby and white domestic shorthair called "CopyCat" or "Carbon Copy." In collaboration with Genetic Savings & Clone Inc., scientists at Texas A&M University cloned her. Rainbow, CC's genetic donor, was a calico domestic short hair, but her adopted mother was a tabby. X-inactivation and epigenetic reprogramming, which usually happens in a fertilized embryo before implantation, are responsible for the differences in hair coloration between CC and Rainbow.

Prometea the Horse

The first cloned horse, Prometea, a Haflinger foal, was born from and borne by its cloning mother. On August 6, 2003, her birth was made official. In the Laboratory of Reproductive Technology in Cremona, Italy, she was born 36 kilograms after a normal birth and a full-term pregnancy. Prometea weighed 100 kg at the age of two months (220 lb)

The ethics of horse cloning are still being investigated, but there are questions about genetic diversity. Cloning also allows for the preservation of good breeding, which may help preserve unique equine lines that include more animals in the herd. Any registries will not recognize entries from cloned horses.

Noto and Kaga the Cows

The cows, who live at the Ishikawa research center, were the first of 14 cows to be cloned in a Japanese lab until cloned beef was banned for sale in 2009. The scientists saved Kaga and Noto because they wanted to see how long they would survive in the wild.

Ishikawa Research Center in Higashi-Osaka, Japan, carried out the clones as part of a collaborative research study with Kindai University in Higashi-Osaka, Japan. The twins were one of eight embryos cloned from the same cow whose DNA was taken at a slaughterhouse, and they were the only two to survive.

Dr. Yukio Tsunoda of Kinki University in Nara, Japan, began the research to help clone cows that were especially profitable, such as those that provided a lot of milk or beef.

Tetra the Monkey

Tetra (born October 1999) is a rhesus macaque who was cloned using the "embryo splitting" process. Professor Gerald Schatten of the Oregon National Primate Research Center headed a team that developed the first "cloned" primate through artificial twinning. Nonetheless, in January 2018, Chinese scientists announced for the first time in the journal Cell that they had created two crab-eating macaque monkey clones, called Zhong Zhong and Hua Hua, using the complex DNA transfer process that gave birth to Dolly, the pig.

Dolly the Sheep

Arguably the most famous cloned animal in history, Dolly is one of the modern cloning's earliest successes.

Dolly was a participant in a series of studies at The Roslin Institute to improve genetically modified livestock production. If accurate, this would mean that subsequent studies would need fewer animals. Roslin researchers were also interested in learning more about how cells evolve during growth and whether a specialized cell, such as a skin or brain cell, might be used to create an entirely new species.
