However, the cloning was done from early embryonic cells, while the sheep Dolly in 1996 was cloned from an adult cell. [82] Megan and Morag were sheep cloned from differentiated embryonic cells in 1995. Dolly (1996–2003), first cloned mammal from adult somatic cells. She had six lambs. [83]
The best current cloning techniques have an average success rate of 9.4 percent, [52] when working with familiar species such as mice, while cloning wild animals is usually less than 1 percent successful. [53] In 2001, a cow named Bessie gave birth to a cloned Asian gaur, an endangered species, but the calf died after two days.
Cloning animals requires procedures that can cause pain and distress, and there can be high failure and mortality rates.” Being able to produce genetically identical monkeys could be useful ...
The first mammalian cloning (resulting in Dolly) had a success rate of 29 embryos per 277 fertilized eggs, which produced three lambs at birth, one of which lived. In a bovine experiment involving 70 cloned calves, one-third of the calves died quite young. The first successfully cloned horse, Prometea, took 814 attempts. Notably, although the ...
ViaGen began by offering cloning to the livestock and equine industry in 2003, [20] and later as ViaGen Pets included cloning of cats and dogs in 2016. [21] ViaGen's subsidiary, start licensing, owns a cloning patent which is licensed to their only competitor as of 2018, who also offers animal cloning services. [22] (Viagen is a subsidiary of ...

The public-private effort underpinning the largest wildlife crossing in the world, under construction near L.A., has inspired an initiative to replicate it across California.
The San Diego Zoo established the first "frozen zoo" program in 1972. The first frozen zoo was established at the San Diego Zoo by pathologist Kurt Benirschke in 1972. [3] [4] [5] At the time there was no technology available to make use of the collection, but Benirschke believed such technology would be developed in the future. [6]
