On this day in 1996, Dolly the sheep—the first mammal to have been successfully cloned from an adult cell—is born at the Roslin Institute in Scotland. Originally code-named “6LL3,” the cloned lamb was named after singer and actress Dolly Parton.
An extinct animal has been resurrected by cloning for the first time—though the clone died minutes after birth. Findings revealed January 23 in the journal Theriogenology describe the use of frozen skin in 2003 to clone a bucardo, or Pyrenean ibex, a subspecies of Spanish ibex that went extinct in 2000.
Since Dolly
This has created a market for commercial services offering to clone pets or elite breeding livestock, but still with a $100,000 price-tag. The advances made through cloning animals have led to a potential new therapy to prevent mitochondrial diseases in humans being passed from mother to child.Dolly was important because she was the first mammal to be cloned from an adult cell. Her birth proved that specialised cells could be used to create an exact copy of the animal they came from.

No, not at all. A clone produces offspring by sexual reproduction just like any other animal. A farmer or breeder can use natural mating or any other assisted reproductive technology, such as artificial insemination or in vitro fertilization to breed clones, just as they do for other farm animals.

Kita reported, from the uterine tube of a cow -- into unfertilized cows' eggs whose own genetic material had been removed. The genes from the adult cells took over and directed the cells to develop into calves that are genetic identical twins of the cows whose cells were used for cloning. Dr.
Since then, scientists have cloned more than 20 species—from cows to rabbits to dogs—using this technique, but the Chinese effort marks the first time that non-human primates have been cloned successfully in the same way.
How are animals cloned? In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed.
Animal cloning from an adult cell is much more difficult than from an embryonic cell. So when scientists working at the Roslin Institute in Scotland produced Dolly, the only lamb born from 277 attempts, it was a major news story around the world.
Dolly was cloned from a mammary gland cell taken from an adult Finn Dorset ewe. Dolly the sheep; cloningDolly the sheep was successfully cloned in 1996 by fusing the nucleus from a mammary-gland cell of a Finn Dorset ewe into an enucleated egg cell taken from a Scottish Blackface ewe.
Dolly died on February 14, 2003, at age six from a lung infection common among animals who are not given access to the outdoors. It probably had nothing to do with her being a cloned animal, says Wilmut, now an emeritus professor at the The Roslin Institute at the University of Edinburgh where he did his initial work.
Mouflon. A European mouflon lamb was the first cloned endangered species to live past infancy. Cloned 2001. A cloned baby mouflon was born to a domestic sheep in a successful interspecies cloning of an endangered species in Iran in 2015.
Two years later, researchers in Japan cloned eight calves from a single cow, but only four survived. Besides cattle and sheep, other mammals that have been cloned from somatic cells include: cat, deer, dog, horse, mule, ox, rabbit and rat. In addition, a rhesus monkey has been cloned by embryo splitting.
Cloning is a complex process that lets one exactly copy the genetic, or inherited, traits of an animal (the donor). Livestock species that scientists have successfully cloned are cattle, swine, sheep, and goats. Scientists have also cloned mice, rats, rabbits, cats, mules, horses and one dog.

Death. On 14 February 2003, Dolly was euthanised because she had a progressive lung disease and severe arthritis. A post-mortem examination showed she had a form of lung cancer called ovine pulmonary adenocarcinoma, also known as Jaagsiekte, which is a fairly common disease of sheep and is caused by the retrovirus JSRV
