[Human cloning. (Do we have too much courage or not enough?) New perspectives in medicine]

Cloning mammals including man has become a real possibility of these years. The result obtained in sheep and cattle demonstrated that technical problems have been solved and now other disciplines--philosophy, ethics, law etc are confronted with this challenge. On one side we have to look for all risks and adopt adequate responsibility, on the other side to consider medical benefits by solving problems with reproduction, organ transplantation and inherited diseases. As the last but not least we have to establish formal rules and to introduce the conception into all disciplines involved, in the first place into genetics. Trying to contribute to the adaptation of formal genetics to the new situation we propose to link the donor and the recipient of the nucleus with a triple line in pedigree schemes.
