Human Cloning: Human Clones
built 642 days ago
Because of experience with animal clones, it is reasonable to conclude that future human cloning experiments will have the same high failure rates. The public has heard reassurance that the possibility of performing prenatal genetic screening exists as a way to control quality. If these groups plan on using current routine prenatal diagnosis for the detection of chromosomal and/or other genetic abnormalities, they will not detect the types of epigenetic disturbances that may occur with cloning. There are no extra tools in the developmental pipeline to help improve detection.

With no law against human cloning, the Food and Drug Administration took notice. Agents visited Boisselier at Hamilton College. They then arranged a visit to the lab at Nitro and struck a deal with her and Hunt last spring.

Students should be able to write lists of ethical standards that detail the formation of their opinions about whether or not human cloning should be allowed. Survey questions should be drawn from their individual lists of standards. Students may decide to change their opinion after the survey results are in. Students should be able to support their opinions with facts from their Internet research.

In 1978 David Rorvik claimed in his book In His Image: The Cloning of a Man that he had personal knowledge of the creation of a human clone. A court case followed. He failed to produce corroborating evidence to back up his claims; now regarded as a hoax.

[T]he mystery didn't last for very long. Boisselier inadvertently tipped her hand when she testified before the National Academy of Sciences in Washington D.C. last week on why human cloning should be allowed. "She gave many clues in that testimony," says Joe Lauria, a U.S. correspondent with the Sunday Times of London who pressed to find the lab's location for the British paper.

Randy Jirtle and his team at Duke University, Durham, claim to have discovered that a key gene restraining embryo growth could not be switched off during human cloning. The deactivation of this gene during animal cloning is widely blamed for "large offspring syndrome", which has plagued projects to clone cattle, sheep and other mammals.
