  1. 1. CLONING
  2. 2. 2 • • • • • • • • • Topics: What exactly is cloning?? Ethical issues of human cloning History of cloning (humans) Experiments conducted(Failed) Future of human cloning Process of cloning Medical issues Pro’s and con’s conclusion
  3. 3. What exactly is cloning? 3 Cloning is the creation of an organism that is an exact genetic copy of another.  This means that every single bit of DNA is the same between the two! 
  4. 4. Dolly the sheep 4 She was born on 5 july 1996. She was cloned by Ian Wilmut and keith campbell in Scotland Was the first mammal to be cloned Died from a progressive lung disease.
  5. 5. Herd of mice 5 The cloned mammals was a mouse (named "Masha") , in the Soviet Union. The cloning was done from an embryo cell. The first mouse from adult cells, Cumulin, was born in 1997 at the University of Hawai'i at Mānoa. Over a dozen clones as of 2002.
  6. 6. Cat (CC) 6 Was born in December 2001, scientists at Texas A&M University created the first cloned cat, CC (CopyCat).
  7. 7. 7
  8. 8. History of Cloning: 8 South Korean scientists create several cloned human embryos which they only allowed to develop for a short while – just long enough to extract embryonic stem cells which could be used in the treatment of disease.  This was the world's first ever cloned human embryo in 2004. 
  9. 9. Experiments conducted: Failed Experiments 9 1999 Scientists secretly placed a human cloned embryo into a pig. The cell only lived to be 32 days old. Dec. 2002 A company called Clonaid announced that they successfully cloned the first human. Experts say it is impossible for the company to clone a human due to inadequate technology.
  10. 10. Future of Human Cloning 10 “Either we control gene technology today, or technology will redesign us by tomorrow.”
  11. 11. Process of Cloning: 11 Remove nucleus Human egg donor Remove cells from person to be cloned Donor egg Cell Surrogate mother with cloned baby Egg fused with cell Fuse cell and enucleated egg with electricity Embryo Implant embryo into surrogate mother
  12. 12. Medical issues: 12 • • • • • • • • • Possible miscarriage or still birth Deformities Unforeseen deaths in later life of the clone Health risks from mutated genes Developmental delays Lung problems Heart defects Neurological disorders Unstable immune system
  13. 13. Pros and Cons: 13 Pro’s •Cloned body parts can serve as backup systems for humans •Solution to infertility •Combat genetic diseases •Replicate animals for research purposes •Enable alterations of plants & animals. •Produce people with desirable traits Con’s •Weaken diversity & ability of adaptation •Production of undesirable traits •Technical & economic barriers: cost effective? Reach the Common man? •Invites malpractices into society •Human & animals rights at stake •Ethical & moral principles •Undermining human life •Devalue mankind •Human’s acting as God.
  14. 14. 14 Cloning looks like a degrading of parenthood and a perversion of the right relation between parents and children. -Leon Kass….!! Thank You!
