Final answer:
Cloning is a method of reproduction that produces genetically identical organisms through a single parent organism. It does not involve gamete fusion or genetic variation.
Step-by-step explanation:
Cloning is a method of reproduction that involves creating an exact genetic replica of an organism. It does not involve the fusion of gametes or genetic variation, but it does produce genetically identical organisms through a process called mitosis. Cloning involves a single parent organism, as the offspring are an exact copy of the parent.
