Dolly's white face was one of the first signs that she was a clone because if she was genetically related to her surrogate mother, she would have had a black face. Because Dolly's DNA came from a mammary gland cell, she was named after the country singer Dolly Parton.

How old was Dolly the sheep when she died?
Dolly the sheep was just six and a half years old when she died, over half the age most sheep live to. Yet despite her relative youth, she was also thought to be suffering from osteoarthritis, a disease usually found in much older sheep.
Which sheep is Dolly identical to?
Dolly 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. Carried to term in the womb of another Scottish Blackface ewe, Dolly was a genetic copy of the Finn Dorset ewe.
What happened to Daisy the cloned sheep?
Sadly, in 2003 Dolly died prematurely at the age of 6.5 years after contracting ovine pulmonary adenocarcinoma, a form of lung cancer common in sheep that is caused by the retrovirus JSRV.
When did Dolly get arthritis?
Over the years, Dolly had a total of six lambs with a Welsh Mountain ram called David. Their first lamb, Bonnie, was born in April 1998. In 2001, Dolly was diagnosed with arthritis after farm staff noticed her walking stiffly.
Is the cloned sheep Dolly still alive?
She was born on 5 July 1996 and died from a progressive lung disease five months before her seventh birthday (the disease was not considered related to her being a clone) on 14 February 2003. She has been called "the world's most famous sheep" by sources including BBC News and Scientific American.
What happened to Dolly the sheep offspring?
After Dolly gave birth to her last lambs in September 2000, it was discovered that she had become infected by a virus called Jaagsiekte sheep retrovirus (JSRV), which causes lung cancer in sheep. Other sheep at The Roslin Institute had also been infected with JSRV in the same outbreak.
When was the first human cloned?
For a time late last year, it seemed possible that human cloning had been accomplished. On Dec. 27, 2002, Brigitte Boisselier held a press conference in Florida, announcing the birth of the first human clone, called Eve.
Has anyone been cloned?
Have humans been cloned? Despite several highly publicized claims, human cloning still appears to be fiction. There currently is no solid scientific evidence that anyone has cloned human embryos.
How many mothers did Dolly have?
Well, actually, Dolly had three mothers. One mother gave Dolly her DNA, one mother supplied an egg, and the third mother, her surrogate mother, gave birth to her.
Would a clone of a dead relative or pet have the same personality?
Myth: Clones have exactly the same temperament and personality as the animals from which they were cloned. Temperament is only partly determined by genetics; a lot has to do with the way an animal has been raised.
What was the first extinct animal cloned?
A cloned Pyrenean ibex was born on July 30, 2003, in Spain, but died several minutes later due to physical defects in the lungs. This was the first, and so far only, extinct animal to be cloned.
How many Dolly clones are there?
Scientists made 4 clones of Dolly the sheep — here's what happened to them all.
What has been cloned since Dolly?
However, it is impossible to predict what will happen in science – before 1997 most scientists would have claimed that Dolly could never be created. A few other species have been cloned since Dolly; from mice, rats and rabbits to dogs, cats, monkeys and wolves.
What health problems did Dolly the sheep have?
At the time of her euthanization, Dolly was noted to have arthritis and had a form of lung cancer called ovine pulmonary adenocarcinoma, which is also known as jaagsiekte. It is a fairly common disease in sheep, particularly in those kept indoors. For security reasons, Dolly had to sleep inside.
