About Reproductive Cloning

Reproductive cloning takes DNA from an animal and uses it to create a new version of that animal. The clone is not identical to the original animal, but does have identical chromosomal or nuclear DNA.

  1. The Process

    • Scientists take genetic material from a donor egg, and put it in an egg without a nucleus. They stimulate cell division of the new egg using chemicals and electrical currents, and place it in a female host until birth.

    Against

    • Some of those against reproductive cloning say it could diminish the uniqueness of individuals, and it could possibly lead to dangerous attempts at genetic engineering.

    In Favor

    • Some of those in favor of reproductive cloning say it is a reproductive right, it will help parents of a deceased child grieve and move forward, and that it can help infertile couples.

    Risks/Safety

    • About 95 percent of animal cloning has ended in miscarriage, stillbirth or some life-threatening condition. Some researchers believe reproductive cloning is unsafe and dangerous.

    Outlook

    • Human reproductive cloning is opposed by many in the scientific and medical communities, as well as the public. It is believed human cloning would result in the same health problems and loss of life encountered in animal cloning.
