It is here that concerns are loudly voiced and take up headlines in the media.
The public and the medias views on the future of cloning often ignore some of its potential benefits: The cloning of human embryos for reproductive purposes is illegal at this time.
Some of the same issues that arose from in vitro fertilization will be revisited (e.g., infertile couples, replacing the death of an infant).
Cloning has opened many doors that could lead to remarkable medical advancements but, as with all new technologies, it will be accompanied by ethical and social dilemmas.
Identical twins exhibit different personalities and behavior because environment also plays a major role on who we become.
At any rate, there have been significant difficulties with cloning primates, including an extremely low success rate and a high number of abnormalities.
, What genes are involved in the control of this event? The problems may be due to the experimental conditions under which the eggs are handled or may be an inherent problem that arises because these animals only have one parent.
Normally, half the chromosomes of the new individual come from a sperm cell and half from an unfertilized egg but in a clone all of the genetic material (except mitochondrial DNA) comes from the donor nucleus. Genetic manipulation of cloned animals is the future direction of the cloning frontier.
Clones: A group of genetically identical organisms.
Ever since the belief that cloning was a possibility, and especially since it has been developed, it has been a major conflict in the ethical world of values.
