Cloning is the creation of a genetically identical
organism through non-traditional reproductive means. It involves creating an artificial
twin based on the DNA of something that already exists (plant, animal or other
organism).
There are several different types of cloning,
and not all cloning leads to the reproduction of an identical twin of what is being
cloned. The type that is most often argued about in the media and in the legislature is
reproductive cloning (the most famous example was Dolly the cloned sheep). DNA from
another sheep was used to create a cloned embryo which grew to be Dolly, a genetic
replica of the original sheep. She lived a full life and had babies of her own, proving
that cloning is possible. Cloning can also be used to create food products - a
technology that is currently under development as a means of addressing world hunger and
scarcity of resources.
