Animal clones: Dolly, Mini-Winnie and Co.
20 years ago, the world was stunned by the creation of Dolly the sheep. Scientists have since tried their hand at copying other animals, from mice and racing mules to kittens and fighting bulls.
Dolly - the one who started it all
This woolly miracle started out in a test tube and was born on July 5, 1996, to three mothers - one provided the egg, the second the DNA and the third was the surrogate. Dolly was the world's first mammal cloned from an adult cell. The sheep that made history lived to be six, when she was put down after developing a lung disease. Dolly is on display at Edinburgh's National Museum of Scotland.
Half horse, half donkey
Idaho Gem is the very first cloned mule. Born in 2003 in - you guessed it - a town in Idaho, he is an identical genetic copy of his champion racing mule brother. Idaho Gem lived up to expectations and became a successful racing mule. Tougher and more productive than horses, mules are a - usually sterile - cross between a female horse and a male donkey.
CC cat
The world's first cloned pet was a cat. The Texas scientists who created the clone in 2001 called the furball CC, for carbon copy. Commercial pet cloning hasn't taken off, however, much to the dismay of devoted pet owners.
Five sisters
Noel, Angel, Star, Joy and Mary were born on Christmas Day 2001 at PPL Therapeutics - which is the company that helped make Dolly the sheep: The five healthy female piglet clones, PPL said, had the genetic capability to allow their organs to be transferred to the human body without being rejected.
Desert beauty
Injaz ("Achievement") is the first cloned female dromedary, that is one-hump, camel. The gangly Arabian camel was born in 2009 at the Camel Reproduction Center in Dubai. Used for transport, riding and racing, camels still play an important role today in the Persian Gulf society.
Join the fray
Spanish scientists cloned a fighting bull they named Got. In this 2010 photo, the little fellow, cloned from the tough fighting bull Vasito, doesn't look ferocious yet at all. Got's mom was a serene black and white milk cow surrogate.
Monkey biology
Unlike Dolly, who was created using a procedure called nuclear transfer, little Tetra the rhesus macaque was created through a technique called embryo splitting. In 2000, scientists in Oregon presented the little primate they had successfully cloned for the first time. Above, Tetra, which means four in Greek, is four months old.
Fido forever?
A team of researchers in South Korea managed to clone the first canine in 2005: the Afghan hound Snuppy. In 2014, a biotech company based in Seoul cloned another dog, this one from a 12-year-old dachshund that belongs to a caterer in London who won the procedure in a competition. The result: Mini-Winnie. Experts, however, warn of cloning pets, arguing the animals won't necessarily be the same.
