Exact duplicates, also known as clones, are two or more items that are identical in every way. They have the same shape, size, color, and other characteristics. Clones are often created through a process of replication, where one item is copied exactly to create another. This can be done with physical objects, such as toys, or digital objects, such as computer files. Clones can also be created through genetic engineering, where the DNA of one organism is used to create an exact duplicate.
