Rifins: A second family of clonally variant proteins expressed on the surface of red cells infected with Plasmodium falciparum.
However, in all 10 specimens (100%), at least one of the primer combinations showed an amplification product, indicating the presence of a population with clonally rearranged immunoglobulin genes.
The researchers say the results indicate that the benefits of sexual reproduction outweigh its costs when the surroundings are varied, but in constant environments sex is not advantageous enough to be a viable strategy - reproducing clonally makes more sense.
Wolbachia can kill infected males outright (male killing), cause male offspring to develop into females (feminization), cause females to reproduce asexually or clonally (parthenogenesis), or kill the offspring of an uninfected female when its mate is infected (cytoplasmic incompatibility).
The researchers surmised that MCPyV is likely to play an etiologic role in Merkel cell carcinoma because the virus is clonally integrated in the tumor genome (Science 2008;319:1096-100).
This means that the tree consists of a scion or top portion that bears a clonally propagated variety and a rootstock or bottom portion that is selected for vigor and disease resistance.
By the late 1970s and early 1980s, the realization that antibody-producing cells were clonally selected focused attention on what was happening at the genetic level.

The occurrence of naturalised populations of a clonally reproduced plant at several disparate locations of northern Australia is a conundrum.
Inflammatory cuffs are frequently observed in normal white matter contiguous with, or distant from, MS plaques of all ages; conversely, lymphocytes may be absent in some zones of early MS lesions with extensive demyelination; (7,18) and, contrary to the findings in EAE, major histocompatibility complex (MHC) Class I-restricted, clonally expanded CD8+ T-cells comprise the bulk of the lymphocytic infiltrate in MS.
CAMRSA strains are epidemiologically and clonally unrelated to hospital-acquired strains (Palavecino, 2004).
