Pictures?
It would be great if someone could add a picture of Dolly the sheep. Stancel 20:10, 19 May 2005 (UTC)
You stated
" (currently, both the egg cell and its transplanted nucleus must be from the same species)."
I thought that cow egg cells had been used to clone other species, ie

Alright, what "human-rabbit hybrid" was cloned in China? If I can't get a source for this I'm going to remove it---Ricimer
The Chinese cloning in 1963 should perhaps be qualified as "reported" - the only online references I saw are the PBS online entry, and dozens of Chinese government websites extolling China's prowess in cloning, making one suspicious that this is a government propaganda thing. Is there a non-Chinese scientific source that reports on what was actually accomplished back then? Stan 15:22, 9 Apr 2004 (UTC)
Hello. I found some references which indicate the term "clone" is rather older than the previously reported origin in 1963. I've put the refs in clone rather than here to avoid cluttering. Hope that works. -- On a related note, does it seem odd to you that this article is not itself named clone ? Should this article have some other name such as clone (nonhorticultural) ? That's clumsy, but more accurate perhaps. Happy editing, Wile E. Heresiarch 14:33, 14 May 2004 (UTC)
Why all the redundant articles; clone, cloning, clone (genetics)? Maybe even more. 213.236.117.2 07:34, 26 Jul 2004 (UTC)
frogs
I believe that in 1951 a team of scientists in Philadelphia cloned a frog embryo. "They took the nucleus out of a frog embryo cell and used it to replace the nucleus of an unfertilized frog egg cell. Once the egg cell detected that it had a full set of chromosomes, it began to divide and grow."
Would that still be considered the modern technique? and if so should it be added to the article? I suppose not for they never let the thing fully mature, just grow. Then they killed it. I think they did it at Robert Briggs lab.
Um and in 1996, before dolly, the same place that cloned dolly also cloned two other sheep from embryos, Megan and Morag.
In 2000 Chinese scientist cloned Yangyang, The second ever cloned female goat. The first died of respiratory problems 36hrs after birth.
In 2003 Prometea was born, the first cloned horse.
- "Mitochondrial DNA, which is not transferred by this process, is generally ignored as its effects on organisms are thought to be relatively minor" - why? surely you need all the info in a cell to create a full clone. The current procedure , by transfer of the nucleus, is not full cloning - what should it be called?
- It's called "nuclear transfer". "Cloning" is what laymen refer to it as; technically, splicing a jellyfish bioflourscence gene into a bacteria is "cloning", it's actually a broad term---Ricimer
