Researchers have observed some adverse health effects in sheep and other mammals that have been cloned. These include an increase in birth size and a variety of defects in vital organs, such as the liver, brain and heart. Other consequences include premature aging and problems with the immune system.

Why do clones fail?
The majority of losses are due to embryonic death, a failure during the implantation process, or the development of a defective placenta.
What are the issues raised with cloning?
The same method used to produce an animal clone—SCNT—could theoretically be used to make a cloned line of human cells with a near genetic match to any person who needed them. The nucleus from a donor cell would be inserted into an egg stripped of its nucleus.
What is the main disadvantage of cloning?
The disadvantage of cloning animals is that prolonged use of this technology would create a genetic bottleneck. With all animals have nearly the same, if not identical, genetic makeup, the species would be at an increased risk of extinction because of the risks of inbreeding.
How much will it cost to clone a human?
Zavos believes estimates the cost of human cloning to be at least $50,000, hopefully dropping in price to the vicinity of $20,000 to $10,000, which is the approximate cost of in vitro fertilization (Kirby 2001), although there are other estimates that range from $200,000 to $2 million (Alexander 2001).
Why is it so hard to clone animals?
When the surrogate dog gives birth, you have an adorable puppy clone of Archie. But creating an Archie clone isn't as simple as it sounds. First, getting the egg from a female dog can be troublesome because dogs don't experience regular ovulation cycles like humans.
Why is cloning morally wrong?
Another common concern is that cloning is morally wrong because it oversteps the boundaries of humans' role in scientific research and development. These boundaries are set by either God (and therefore cloning is wrong because it is “playing God”) or nature (and therefore cloning is wrong because it is “unnatural”).
What are the pros and cons of human cloning?
Human Cloning Pros and Cons
Infertility: Infertile people or same-sex couples could have children made from cloned cells. Organ replacement: A clone, like in the movie, "The Island," could be a source for transplant organs or tissue. (There are ethical issues that arise from this, however.)
How does cloning affect human life?
Moreover, most scientists believe that the process of cloning humans will result in even higher failure rates. Not only does the cloning process have a low success rate, the viable clone suffers increased risk of serious genetic malformation, cancer or shortened lifespan (Savulescu, 1999).
Has anyone been cloned?
Have humans been cloned? Despite several highly publicized claims, human cloning still appears to be fiction. There currently is no solid scientific evidence that anyone has cloned human embryos.
Do clones get weaker?
Myth: Offspring of clones are clones, and each generation gets weaker and weaker and has more and more problems. No, not at all. A clone produces offspring by sexual reproduction just like any other animal.
Who is the first human clone?
On Dec. 27, 2002, Brigitte Boisselier held a press conference in Florida, announcing the birth of the first human clone, called Eve.
How does cloning violate human rights?
The case of therapeutic cloning, the creation of embryos for the purpose of harvesting specialized cells involves violating the dignity of the unborn human being and thus of the entire human species because human life is no longer considered a supreme value, the individual being denied the right to his own life.
