Asexual reproduction in animals is less common than sexual reproduction but it does happen in sea anemones and for example, starfish.
Natural Cloning
Twins are genetically identical because they are formed after one egg cell is fertilised but splits to form two embryos. They have the same genes. As the genes came from both parents they are not clones of either parent, but they are natural clones of each other
Artificial Cloning
It is in fact possible to make clones artificially. The cloning of animals has many important commercial implications. It allows an individual animal that has desirable features, such as a cow that produces a lot of milk, to be duplicated several times.
