Literary Devices and Terms. Literary Devices refers to the typical structures used by writers in their works to convey his or her messages in a simple manner to the readers. When employed properly, the different literary devices help readers to appreciate, interpret and analyze a literary work. Below is a list of literary devices with detailed definition and examples. a
Genetic variation is a fact that a biological system â individual and population â is different over space. It is the base of the genetic variability of different biological systems in space.Genetic variation is based on the variation in alleles of genes in a gene pool.It occurs both within and among populations, supported by individual carriers of the variant genes. Genetic variation is brought about by random mutation, which is a permanent change in the chemical structure of a gene.utations are likely to be rare and most mutations are neutral or deleterious, but in some instances the new alleles can be favored by natural selection. Polyploidy is an example of chromosomal mutation. Polyploidy is a condition wherein organisms have three or more sets of genetic variation (3n or more).
Abstract. Antigenic variation is the means by which a number of highly pathogenic microorganisms, ranging from the electronmicroscopic human viruses to bacteria to fungi and unicellular protozoan parasites, passively evade immune surveillance.ahoon LA and Seifert S (2011) Focussing homologous recombination: pilin antigenic variation in the pathogenic Neisseria.
