Like everything else in the news about cloning, the article completely passes over the science.
First, the cat's color pattern was decided by individual skin cells very early in embryonic development. This is chance, not genes. The individual cells multiply, carrying the same color, to become the pattern on the adult cat.
Second, and most notably, calico cats (tortoise shell) carry a color in each sex chromosome - that's why 99.9% of calico cats are female (XX female, although there are some XXY male calicos but they're sterile). Fur color depends on which X chromosome is active, and which one is inactive (curled up, as they say)
So, looking at the picture, you'll notice the clone (cc) has only two colors indicating that it is not only a clone of the donor cat, but a 100% exact genetic clone of ONE cell of the donor cat. The other X chromosome is completely inactive.
That's just my observation from the photo because no news article will ever talk about the science behind the hype.

actually we cannot "create matter" excepting maybe a few virtual particles for a few millionths of a second. Cloning is little more than fertilizing an egg with a duplicate genetic code. You really arn't "creating matter" anymore than we create matter through common sexual intercourse.

this is not a sig.
So *THIS* is Schroedinger's Cat?
