1. A group of cells or organisms that are descended from and genetically identical to a single progenitor, such as a bacterial colony whose members arose from a single original cell.
2. An organism developed asexually from another and genetically identical to it, such as an animal produced from an egg cell into which the nucleus of an adult individual has been transferred.
3. A DNA sequence, such as a gene, that is transferred from one organism to another and replicated by genetic engineering techniques.
4. One that copies or closely resembles another, as in appearance or function: "filled with business-school clones in gray and blue suits" (Michael M. Thomas).
v. cloned, clon·ing, clones
1. To make multiple identical copies of (a DNA sequence).
2. To create or propagate (an organism) from a clone cell: clone a sheep.
3. To reproduce or propagate asexually: clone a plant variety.
4. To produce a copy of; imitate closely: "The look has been cloned into cliché" (Cathleen McGuigan).
To grow as a clone.

Because oil palm producers have had no way of knowing at the time of planting which clonal palms will be productive and which will carry the low-yielding mantled phenotype, many were unable to take the risk that they may plant completely unproductive palms.
Mastocytosis is a clonal neoplastic proliferation of mast cells that accumulate in one or more organ systems.
Our objective was to determine genetic relatedness among the isolates, notably clonal relationships between environmental and clinical isolates, and to further explore the relative contribution of different transmission pathways to disease occurrence.
These studies are used to identify clonal populations in specimens with equivocal morphology or immunopheno-type.
While subtypying of STEC isolates using nucleic acid based methods have been used to identify clonal groups and phylogenetic relationships among isolates, these efforts have mainly focused on human clinical isolates.
The existence of intratumor phenotypic heterogeneity was described a few decades ago, but the biological impact of this clonal diversity remains unknown.
coli in their samples, many of which could be placed into 6 clonal populations.
The genetic makeup of Musa acuminata (top), a fertile banana species that gave rise to the seedless Cavendish (bottom) and other clonal varieties people eat today, sheds light on the plant's evolutionary history and ripening process.
Writing in the journal PLoS ONE, the scientists describe their work with samples of Posidonia oceanica, a clonal seagrass that is found in undersea meadows from Spain to Cyprus.
Computer models helped demonstrate that the clonal spread mode of Posidonia oceanica, which as all other seagrasses can reproduce both sexually and asexually, allows them to spread and maintain highly competent clones over millennia, whereas even the most competent genotypes of organisms that can only reproduce sexually are lost at every generation.
