Did you know?

Cloning is the production of a population of genetically identical cells or of organisms asexually produced by a single cell or organism. Cloning is fundamental to most living things, since the body cells of plants and animals are clones that come from a single fertilized egg. More narrowly, the term refers to an individual organism grown from a single body cell of its parent that is genetically identical to the parent. Cloning has been commonplace in horticulture since ancient times — many varieties of plants are cloned simply by obtaining cuttings of their leaves, stems, or roots and replanting them. The body cells of adult humans and other animals are routinely cultured as clones in the laboratory. British researchers achieved the first success in cloning an adult mammal in 1996. They produced a lamb, which they named Dolly, using DNA from an adult sheep.

Etymology

Noun

borrowed from Greek klṓn, klōnós "branch, sprig," perhaps contraction of *klaṓn, from kla-, stem of kláō, klân "to break off, break in two or in pieces" + -ōn, noun suffix — more at clastic

Note: The term clone, first spelled clon, was introduced by the American plant physiologist Herbert J. Webber (1865-1946) in "New horticultural and agricultural terms," Science, vol. 18 (new series), no. 459 (October 16, 1903), pp. 501-03: "Recently, Mr. O.F. Cook, of the Department of Agriculture, has called the writer's attention to the Greek word clon (κλών) meaning a twig, spray, or slip, such as is broken off for propagation, which could be used in the connection desired …Clons, which are groups of plants that are propagated by the use of any form of vegetative parts such as bulbs, tubers, cuttings, grafts, buds, etc., and which are simply parts of the same individual seedlings." The O.F. Cook to whom Webber refers was the American botanist Orator F. Cook (1867-1949). Respelling of the word as clone to mark the long o was suggested by the botanist Charles Louis Pollard ("On the spelling of 'clon'," Science, vol. 22 [new series], no. 551 [July 21, 1905], pp. 87-88).
