Expert subject Genetics date June 2009 A genetic predisposition is a genetics genetic affectation which influences the phenotype of an individual organism within a species or population but by definition that phenotype can also be modified by the natural environment environmental conditions. In the rest of the population, conditions cannot have that effect. Genetic test ing is able to identify individuals who are genetically predisposed to certain disease health problems . Behavior Predisposition is the capacity we are born with to learn things such as language and concept of self. Negative environmental influences may block the predisposition ability we have to do some things. Animal behavior Behaviors displayed by animals can be influenced by genetic predispositions. Genetic predisposition towards certain human behaviors is Ethology scientifically investigated by attempts to identify patterns of human behavior that seem to be invariant over long periods of time and in very different cultures.

Unreferenced auto yes date December 2009 Genetic architecture refers to the underlying genetic basis of a phenotype phenotypic Trait biological trait . A synonymous term is the genotype phenotype map , the way that genotypes map to the phenotypes. The genotype phenotype map has been analyzed in terms of several principal axes epistasis, polygeny, pleiotropy, quasi continuity, modularity, phenotypic plasticity, robustness, and evolvability. Epistasis when the alleles at one Locus genetics locus change the phenotypic effects of genetic variation at another locus, the two genes are said to exhibit epistasis in their interactions. Polygeny when multiple genes contribute to a particular phenotypic character, the map is said to possess polygeny . The genetic architecture in cases of polygeny can be further characterized by the spectrum of contributions of the genes, e.g. many genes of small effect vs. few genes of large effect. Pleiotropy when multiple phenotypic characters are affected by a single genetic variation, the map is said to possess pleiotropy . Quasi continuity when small genetic changes map to small phenotypic changes, the map is said to possess Lewontin quasi continuity Lewontin . Modularity when two different phenotypic characters can be mapped to mostly non overlapping sets of genes, the map is said to possess modularity , though this concept is still in flux in the scientific literature. Phenotypic plasticity Plasticity when a single genotype gives rise to a spectrum of phenotypes, the phenotype is said to have plasticity . The plasticity may occur as different phenotypes among different individuals of the same genotype, or different phenotypes within the lifetime of a single individual, or different phenotypes in response to specific environmental conditions ... there is a significant chance that genetic variation can be produced which produces a net increase ... lines. br Genarch DEFAULTSORT Genetic Architecture Category Genetics Genetics stub ... more details

Unreferenced date December 2009 Orphan date September 2008 In evolutionary biology , genetic anthropomorphism refers to thinking like a gene . The central question is if I were a gene, what would I do in order to reproduce myself . The question is an obvious fallacy genes are incapable of thought . However, natural selection does act in a such a way that those that are most successful at reproducing themselves by following the optimum strategy prosper. Thinking like a gene enables the results to be visualised. This is related to a philosophical tool known as the intentional stance . The most notable genetic anthropomorphist was the British biologist W.D. Hamilton . Hamilton s friend Richard Dawkins popularised the idea. It is important to think like a gene rather than an organism . Anthropomorphism has been criticised on a number of grounds, including that it is reductionist .

To be genetically viable , having a realistic chance of avoiding the problems of inbreeding , a population of plants or animal s requires a certain amount of genetic diversity , and consequently a certain minimum number of members. See effective population size . The minimum is normally somewhere in the region of a hundred unrelated individuals. Where a population has become extremely small in a population bottleneck , due for example to near extinction of the species , it may have lost its genetic viability, and if numbers recover it will be through inbreeding, possibly leaving an unhealthy population. But in fact it provided a more diverse population thus limiting the amount of genetic disorder or repetition. Unreferenced date April 2009 Category Genetics genetics stub ... more details

Genetic Heterogeneity is a phenomenon in which a single phenotype or genetic disorder may be caused by any one of a multiple number of alleles or non allele locus genetics locus mutations. ref Turnpenny and Ellard, Emery s Elements of Medical Genetics, 13th Edition. Elsevier Limited, 2007. ISBN 978 0 7020 2917 2 ref This is in contrast to pleiotropy , where a single gene may cause multiple phenotypic expressions or disorders. Genetic heterogeneity can be classified as either allelic or locus . Allelic heterogeneity means that different mutations within a single gene locus forming multiple alleles of that gene cause the same phenotypic expression. For example, there are over 1000 known mutant alleles of the CFTR gene CFTR gene that cause cystic fibrosis . Locus heterogeneity means that variations in completely unrelated gene Locus genetics loci cause a single disorder. For example, retinitis pigmentosa has autosomal dominant , autosomal recessive , and X linked origins. However, only one mutant locus is needed for the phenotype to manifest.

Genetic redundancy is a term typically used to describe situations where a given biochemical function is redundantly encoded by two or more gene s. In these cases, mutation s or defects in one of these genes will have a smaller effect on the fitness of the organism than expected from the genes function. Characteristic examples of genetic redundancy include Enns, Kanaoka et al. 2005 and Pearce, Senis et al. 2004 . Many more examples are thoroughly discussed in Kafri, Levy & Pilpel. 2006 . The main source of genetic redundancy is the process of gene duplication which generates multiplicity in gene copy number. A second and less frequent source of genetic redundancy are convergent evolution ary processes leading to genes that are close in function but unrelated in sequence Galperin, Walker & Koonin 1998 . Genetic redundancy has classically aroused much debate in the context of evolutionary biology Nowak et al., 1997 Kafri, Springer & Pilpel . 2009 . From an evolutionary standpoint, genes with overlapping functions implies minimal, if any, selective pressure s acting on these genes. One therefore expects that the genes participating in such buffering of mutations will be subject to severe mutational drift diverging their functions and or expression patterns with considerably high rates. Indeed it has been shown that the functional divergence of paralogous pairs in both yeast and human is an extremely rapid process. Taking these notions into account, the very existence of genetic buffering, and the functional redundancies required for it, presents a paradox in light of the evolutionary concepts. On one hand, for genetic buffering to take place there is a necessity for redundancies of gene function, on the other hand such redundancies are clearly unstable in face of natural selection ... utilization of genetic redundancy through responsive backup circuits.

Genetic admixture occurs when individuals from two or more previously separated populations begin interbreeding. Admixture results in the introduction of new genetic lineages into a population. It has been known to slow local adaptation by introducing foreign, unadapted genotypes known as gene swamping . It also prevents speciation by homogenizing populations. Genetic admixture often occurs when a geographic barrier separating populations, such as a river or isthmus , is removed or when anthropogenic activities result in movement of populations for example invasive species . One example of genetic admixture resulting from the introduction of an invasive species is provided by the Cuban brown anole . Several isolated populations of this species exist in the native range of Cuba . However in the introduced range of Florida , these populations freely interbreed, forming an admixed population.

Cleanup date November 2009 On Genetic Interests Family, Ethnicity, and Humanity in an Age of Mass Migration is a book by Frank Salter . Genetic interests is a non technical term designating an organism s inclusive fitness or copies of its genes. Salter s book is the first attempt to map the distribution of human genetic interests. ref http www.amazon.com dp 1412805961 On Genetic Interests ref Salter adopts the second meaning copies of an individual s gene patterns. The need to have this gap in knowledge filled is evidenced by the enthusiasm with which the book was received. The book carried endorsements from several high profile evolutionary thinkers Quotes ref http www.amazon.com dp 1412805961 On Genetic Interests ref Edward O. Wilson, Harvard University This is a fresh and deep contribution to the sociobiology of humans, combining genetics with social science in original ways. Pierre van den Berghe, University of Washington, Seattle The book greatly expands Hamiltonian kin selection by making ethnies in control of territory the central arena of selfish genery in a modern world of mass migration. Iren us Eibl Eibesfeldt, Max Planck Society Salter argues that all humans have a vital interest in genetic continuity that is threatened by mass migration. Salter advocates non aggressive universal nationalism as part of a balanced fitness portfolio that includes investments in three levels of genetic interests family, ethny, and the species as a whole. The synthesis is persuasive the policy formulations provocative. Michael T. McGuire, UCLA Salter has provided us with a deep and compelling ...
