A- Natural cloning:
Do clons occur naturally ?
1-In some plants and single celled bacteria produce genetically identical offspring through a process called asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism.

2-Identical twins, occur in humans and other mammals they are produced when a fertilized egg splits creating two or more embryos that carry almost identical DNA
Identical twins have nearby the same genetic makeup as each other but they are genetically different from their parents

B-Artificial cloning:
There are 3 types of artificial cloning

1-Therapeutic cloning
  Produce embryonic stem cells for experiments aimed to creating tissues to replace injured or diseased tissues....to be discussed.

2-Gene cloning
  Produce copies of genes or segments of DNA....to be distocussed.

3-Reproductive cloning
  Produce copies of a whole animal....to
 be discussed.
