When the world learned in 1997 of Dolly the sheep, the first clone produced from an adult mammal, a broad public discussion about the ethics of human cloning ensued, largely focused on the nature, meaning, and future of human procreation. (thenewatlantis.com)
Twenty years have passed since Dolly the sheep was born by cloning (somatic cell nuclear transfer, SCNT) but the results of non-human mammalian cloning are very poor, and cause animal diseases and huge biological losses. (sibi.org)
Let's wind back the clock: these scientists had already carried out successful human nuclear transfer into an unfertilised egg before Dolly the sheep clone had been made. (globalchange.com)

Dolly's creation triggered fears of human reproductive cloning, or producing genetic copies of living or dead people, but mainstream scientists have ruled this out as far too dangerous. (cyprus-mail.com)
Most natural cloning occurs in those species that produce their descendants asexually, that is, without combining the male and female genetic material. (who.int)
However, an animal created through this technique would not be a precise genetic copy of the source of its nuclear DNA because each clone derives a small amount of its DNA from the mitochondria of the egg (which lie outside the nucleus) rather than from the donor of cell nucleus. (who.int)
Using in vitro fertilization, doctors created embryos and then tested them for the genetic disease. (cnn.com)
