What is the primary purpose of cloning in biology?

The primary purpose of cloning in biology is to copy a cell, cell product, or organism from an original source. Cloning allows scientists to produce genetically identical copies of biological entities. This process is crucial for various applications, including research, agriculture, and medicine. For example, in agricultural practices, cloning can be used to propagate plants with desirable traits, ensuring that those traits are preserved in the new generations. In medical research, cloning plays a role in stem cell research and the production of genetically identical cells that can be used for tissue and organ transplants.

The emphasis on copying ensures that the resulting clone retains the same genetic information as the original, which is fundamental to the technique. This straightforward replication contrasts with the concept of enhancing biodiversity or creating varied populations, which involves more complex genetic manipulation and breeding approaches.
