Part 5 - Reproductive Cloning
Reproductive Cloning is almost a form of asexual reproduction. By asexual reproduction is meant reproduction requiring only one donor of genetic material rather than two. Rather than having half of all of its chromosomes donated by one person and the other half by another, all 46 of a human clone's chromosomes would come from the single donor of the DNA. It is nearly but not exactly a form of asexual reproduction because a small amount of the egg donor's genetic material (mitochondrial DNA) is left behind on the mitochondria of the egg.
A human created through Somatic Cell Nuclear Transfer would be nearly a genetic twin of the DNA donor and if not for the mitochondrial DNA he or she would be an exact genetic twin.
