Limitations of Reproductive Cloning
Original Paragraph:
Cloning is defined as using the cells of one
living subject, plant or animal, to create another duplicate subject. A cloned
subject will be identical to its parent. Cloning has become the center of a
huge debate over the advantages and disadvantages of producing clones, especially
of animals and humans. While this technology could be useful for laboratory
studies and for creating desirable livestock, there are several disadvantages of cloning that should be considered.
One of the biggest disadvantages of cloning is that the technology is still so uncertain. Dolly the sheep, the first mammalian clone, was born in 1996. While she was initially successful, she died young of a disease not normally seen in sheep of her age. Scientists are still unsure of any genetic mutations that might occur when an animal is cloned. Also, while Dolly was a successful clone, there were hundreds of failed clones before she was made, including several dead fetuses. Other cloned animals have turned out horribly deformed.

Key Ideas:
- There are several limitations that reproductive cloning holds.
- The major drawback of cloning is that technology could be so risky. For example, Dolly the sheep was born in 1996 by cloning. She was originally successful, however, due to a disease that is unusually found in sheep of her age, she died in a young age.
- There were hundreds of failed clones before Dolly was made.
- Caused the death of several fetuses. Other cloned animals have turned out horribly deformed.

Paraphrasing:
There are numerous limitations of cloning that should be
reflected upon. According to my research, the major drawback of cloning is the
technology it would be highly risky for anyone to do this. The well-known sheep
named Dolly who was the first mammalian clone, died in a young age caused by a
disease that would not normally be found in a sheep that was her age. Scientists
are uncertain of any genetic alterations that have a chance to occur during the
cloning of an animal. They have also tried cloning various sheep’s before Dolly
which is soon followed by their death.
