That is because commercial grapevines are propagated from cuttings and are genetically identical clones.
Then, within several days, embryos genetically identical to the baby were created, from which stem cells were derived.
Dolly and the donor sheep were genetically identical, like twins, except that the clone was much younger than the other.
It allows the plants in question to reproduce asexually, thus cloning themselves and creating seeds which are genetically identical to their parent.
They are tiny animals and polyps that exist as genetically identical individuals, and can eat, defend themselves and kill plankton for food.
Perlegen, a spinoff of Affymetrix, a DNA chip pioneer, is taking advantage of the fact that any two humans are 99.9% genetically identical.
Many of the domesticated foxes hardly resembled their wild-type relatives at all, in both appearance and behavior even though they were genetically identical.
The baby camel, weighing 30kg, has been confirmed as being genetically identical to the camel the cells were taken from, the paper reported.
The existence of genetically identical siblings will have to be taken into account, but the new technology will make iris-scanning and hand-geometry systems seem quaint.
Since new colonies would be genetically identical with those that spawned them, it is likely that all the C. biroi on Okinawa have identical genes.
The cloning element is there purely for the purposes of creating tissues genetically identical to the patient that won't be rejected, and that's a nice idea.
CNN: Human stem cell cloning: 'Holy Grail' or techno-fantasy?
On the other hand it might help explain patterns of disease associated with ageing as cells whose ancestors were genetically identical slowly diverge from one another.
ECONOMIST: The next advances in genomics may happen in China
An island-full of identical individuals could be wiped out by an infection, just as entire crops of genetically identical plants may succumb to plague and pestilence.
Of the 50 patients and 33 wild armadillos the researchers analyzed from the U.S., 25 patients and 28 armadillos shared a genetically identical strain of leprosy bacteria.
Dr Jaisson suspects, though he has not yet proved for sure, that all the ants in the colony are genetically identical like the cells in a single human body.
Perlegen, a spinoff of DNA chip pioneer Affymetrix (nasdaq: AFFX - news - people ), is taking advantage of the fact that any two humans are 99.9% genetically identical.
The cloned cells would be genetically identical to the patient's own, so they could replace part of an ailing brain or heart without touching off a full-scale attack from the patient's immune system.
Sir Ian and his team fused the genetic information from an adult sheep cell nucleus with an egg cell to form an embryo that developed into a genetically identical copy of the original adult.
Could patients have themselves cloned in order to harvest cells from a genetically-identical embryo, gaining a donor and avoiding the major problem of transplant surgery: rejection of foreign tissue by the immune system?
Because a field trial with a genetically engineered plant may be 10 to 20 times more expensive than the same experiment performed with a plant that has identical properties but that was modified with less precise genetic techniques, genetic engineering with the best techniques has been vastly under-used for the past 25 years.
