unreferenced date May 2010 A genetic carrier or just carrier , is a person or other organism that has Genetics inherited a Phenotype genetic trait or mutation , but who does not display that trait or show symptoms of the Genetic disease disease . They are, however, able to Heredity pass the gene onto their offspring, who may then express the gene. This phenomenon is a direct result of the Dominance relationship Recessive allele recessive nature of many genes. For example, the daughters of Queen Victoria of the United Kingdom Victoria , the princesses Alice and Beatrix, were carriers of the Sex linked X linked hemophilia gene more precisely, an abnormal allele of a gene necessary to produce one of the blood clotting factors . Both had children who continued to pass the gene to succeeding generations of the royal houses of Spain and Russia , into which they married. Males who carried the altered gene had hemophilia, while females simply passed it to about half of their children. Up to 1 in 25 individuals of Northern European ancestry may be considered carriers of mutations that could lead to Cystic Fibrosis . The disease appears only when two of these carriers have children, as each pregnancy between them will have a 25 chance of producing a child with the disease. However, it is also thought that carriers may be more resistant to diarrhea during typhoid fever or cholera , and are therefore not truly asymptomatic. This resistance leads to Heterozygote advantage increased survival of the carriers, thereby increasing the frequency of the altered Cystic fibrosis transmembrane conductance regulator genes in the population. Genetic carrier testing can be used to tell if a person carries one or more mutations of the CF gene and how many copies of each mutation. The test looks at a person s DNA genetic material , which is taken from cells in a blood sample or from cells that are gently scraped from inside the mouth.

Genetic distance refers to the genetics genetic divergence between species or between populations within a species. It is measured by a variety of parameters. Smaller genetic distances indicate a close genetic relationship whereas large genetic distances indicate a more distant genetic relationship. Genetic distance can be used to compare the genetic similarity between different species, such as humans and chimpanzees. Within a species genetic distance can be used to measure the divergence between different sub species. In its simplest form, the genetic distance between two populations is the difference ... individuals is 50.4 among Basques, 41.2 in France and 41.1 in England. Thus the genetic difference between the Basques and French is 9.2 and the genetic difference between the French and the English is 0.1 for the RH negative trait.

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.

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.
