Homonym: clone (Copy)
A "clone" refers to an organism or cell that is genetically identical to another. Cloning can occur naturally, as seen in identical twins, or artificially through scientific methods. In laboratories, scientists can create clones of plants or animals to study genetics or produce specific traits.
Cloning technology has advanced significantly, leading to the creation of cloned animals like Dolly the sheep, the first mammal cloned from an adult cell. This process raises ethical questions and concerns about biodiversity, as cloning reduces genetic variation, which is essential for the health of populations and ecosystems.
