<molecular biology> The process whereby clones are established asexually, where cells all genetically identical, to a single ancestor.

In recombinant DNA technology, the use of DNA manipulation procedures to produce multiple copies of a single gene or segment of DNA is referred to as cloning DNA.

The term covers various manipulations for isolating and establishing clones. In simple systems single cells may be isolated without precise knowledge of their genotype. In other systems partial or complete selection of chosen genotypes can be manipulated with gene cloning.

In plants the term refers to natural or artificial vegitative propagation.
