In 2001, the FDA conducted
research regarding the safety of
meat from cloned livestock

Cloning is seen as unethical
by many
Whether it be humans of
frogs, experimental
reproduction is considered
unjust
Cloning of humans is legal
due to the apparent
immorality in controlling
birth

What is reproductive cloning?
Reproductive cloning is the
duplication of a genome from
an existing organism. The
genome is transferred via
nucleus, which is the basis of all
genetic material within an
embryo (fertilized egg cell).
Methods of cloning
Artificial Embryo Twinning
A simple method of cloning is
artificial embryo twinning. As the
name suggests, an embryo is split
just as twins are produced in
nature.
Somatic Cell Nuclear Transfer
In SCNT, a donor cell from a living
organism is implanted into an
enucleated embryo. The somatic
donor cell fuses via electric current
with the embryo and becomes the new
nucleus.
Notable Cloning Successes
- 1952, a tadpole was first cloned
- 1997, Dolly the sheep
- 2000, Tetra the Rhesus monkey
- 2005, the first cloned dog, a
male Afghan hound
