Cloning
Clones are organisms that are exact
genetic copies. Every single bit of
their DNA is identical
Clones can happen naturally-
identical twins are just one of
many examples
In nature, twins form very early in development when the embryo
splits in two. Twinning happens in the first days after egg and
sperm join, while the embryo is made of just a small number of
unspecialised cells. Each half of the embryo continues dividing
on its own, ultimately developing into separate, complete
individuals. Since they developed from the same fertilized egg,
the resulting individuals are genetically identical.
Clones can be made using
modern cloning technologies
Artificial embryo twinning
Artificial embryo twinning uses the same approach as
natural twinning, but it is carried out in a Petri dish instead
of inside the mother. A very early embryo is separated into
individual cells, which are allowed to divide and develop
for a short time in the Petri dish. The embryo's are then
placed into a surrogate mother, were they finish
developing. Again, since all the embryo's came from the
same fertilized egg,they are genetically identical.
