Refimprove date December 2009 Genetic representation is a way of representing solutions individuals in evolutionary computation methods. Genetic representation can encode appearance, behavior, physical qualities of individuals. Designing a good genetic representation that is expressive and evolvable is a hard problem in evolutionary computation. Difference in genetic representations is one of the major criteria drawing a line between known classes of evolutionary computation. Genetic algorithm s use linear binary representations. The most standard one is an array of bit s. Arrays of other types and structures can be used in essentially the same way. The main property that makes these genetic representations convenient is that their parts are easily aligned due to their fixed size. This facilitates simple crossover operation. Variable length representations were also explored in Genetic algorithm s, but crossover implementation is more complex in this case. Evolution strategy uses linear real valued representations, e.g. an array of real values. It uses mostly gaussian mutation and blending averaging crossover. Genetic programming GP pioneered tree like representations and developed genetic operator s suitable for such representations. Tree like representations are used in GP to represent and evolve functional programs with desired properties. ref http www.sover.net nichael nlc publications icga85 index.html Cramer, 1985 ref Human based genetic algorithm HBGA offers a way to avoid solving hard representation problems by outsourcing all genetic operators to outside agents, in this case, humans.

Unreferenced date April 2008 Expert subject Genetics date April 2008 A genetic isolate is population of organisms that has little genetic mixing with other organisms within the same species. This may result in speciation , but this is not necessarily the case. Genetic isolates may form new species in several ways allopatric speciation , in which two populations of the same species are geographically isolated from one another by an extrinsic barrier, and evolve intrinsic genetic reproductive isolation peripatric speciation , in which a small group of a population is separated from the main population, and experiences genetic drift parapatric speciation , in which zones of two diverging populations are separate, but do overlap somewhat partial separation is afforded by geography, so individuals of each species may come in contact from time to time, but selection for specific behaviours or mechanisms may prevent breeding between the two groups. sympatric speciation , a contentious method of speciation in which species diverge while inhabiting the same place.

Genetic structure refers to any pattern in the genetics genetic makeup of individuals within a population. In the absence of genetic structure, one can infer little to nothing about the genetic makeup of an individual by studying other members of the population. When genetic structure is present, on the other hand, much can be inferred. In trivial terms, all populations have genetic structure, because all populations can be characterised by their genotype or allele frequencies if only 1 of a large sample of moths drawn from a single population have spotted wings, then it is safe to assume that any unknown individual is unlikely to have spotted wings. A more complicated example arises in dense thicket s of plants, where plants tend to be pollination pollinated by near neighbours, and seed s tend to fall and germination germinate near the maternal plant. In such a scenario, plants tend to be more closely related to nearby plants than they are to distant plants and yet they are more likely to breed with nearby plants than they are with distant plants. Thus an inbreeding cycle is created that perpetuates the pattern of plants being closely related to near neighbours. This is a form of genetic structure because one can infer much about the genetic makeup of any individual plant simply by studying plants in its immediately neighbourhood.

Genetic correlation is the proportion of variance that two traits share due to gene tic causes ref Neale, M. C., & Maes, H. H. 1996 . Methodology for genetics studies of twins and families 6th ed. . Dordrecht, The Netherlands Kluwer. ref . Outside the theoretical boundary case of traits with zero heritability , the genetic correlation of traits is independent of their heritability i.e., two traits can have a very high genetic correlation even when the heritability of each is low and vice versa. The genetic correlation, then, tells us how much of the genetic influence on two traits is common to both if it is above zero, this suggests that the two traits are influenced by common genes . This can be an important constraint on conceptualizations of the two traits traits which seem different phenotypically but which share a common genetic basis require an explanation for how these genes can influence both traits. Computing the genetic correlation Estimates of a genetic correlation obviously require a genetically informative sample, such as a twin study .

Genetic saturation is the reduced appearance, which occurs over time, of Divergence sequence sequence divergence rate that results from reverse mutation s, homoplasies and other multiple changes occurring at single sites along two lineage genetic lineages . Genetic saturation is a cause of reticulation in genetic trees, where diverging genetic branches might fuse back into one another before splitting. Two other causes are sequence errors and recombination. Genetic saturation occurs most rapidly on rapidly evolving sequences, such as the hypervariable region of mitochondrial DNA, or in Short tandem repeat such as on the Y chromosome.
