2. Genotype Vs Phenotype genotype vs phenotype. At the moment we understand our phenotype far more completelythan our genotype. This is true even for traits which we understand poorly. http://www.ess.ucla.edu/huge/genotype2.html

Genotype vs Phenotype Living material is unique in that its composition and form is represented in two radically different formats, called phenotype and genotype The physical material itself - an arm, cell, chunk of meat or thymus gland - constitutes its phenotype. It is more than what is visible by eye or microscope however, as it includes the full complement of behaviours, the developmental dynamics, as well as the chemical compositionof the organism. Genetic representations are inscribed in a code in DNA molecules infused throughout all biological tissues. Every cell contains a complete genetic description of not only its own phenotype but of the whole organism encompassing it. A fat cell in the belly contains the complete genetic information for brain neurons as well as itself. Every speck of tissue visible to the eye carries hundreds or thousands of these genetic representations in the chromosomes of its cells. Moreover, they do not merely describe but are part of an elaborate cellular machinery to cause a body part to develop the form of those descriptions. The genotype is the full complement of the genetic information repeated exactly in every body cell. It is a major determinant of the phenotypic attributes of the organism, which is why an egg laid by a hen hatches as a chick instead of a duckling. But, genes are not exclusively responsible for a person's phenotype. The environment also plays an essential role. A baby can be born with fetal alcohol syndrome because the mother abused alcohol during her pregnancy. Also, Japanese children grow up speaking Japanese and British children English, due exclusively to their environment. In general phenotypic traits are specified or "determined" by a combination of genetic and environmental factors.

3. Hospital Practice: Genotype And Phenotype In Cystic Fibrosis Molecular Genetics in Clinical Practice genotype and phenotype in CysticFibrosis LAPCHEE unclear. genotype-phenotype Correlations. How http://www.hosppract.com/genetics/9706gen.htm

Molecular Genetics in Clinical Practice Genotype and Phenotype in Cystic Fibrosis LAP-CHEE TSUI and PETER DURIE University of Toronto Questions about the function of the disease-related gene are still not fully answered, but correlations are emerging between specific mutations and a patient's clinical condition. The strongest link is for pancreatic failure. A second involves azoospermia. Indeed, mutations are being found in males with infertility as the sole sign of disease. Improved knowledge of such patterns may suggest novel approaches to severe cystic fibrosis. Dr. Tsui is Professor of Molecular and Medical Genetics and Geneticist in Chief and Dr. Durie is Professor of Pediatrics and Head, Division of Gastroenterology and Nutrition, University of Toronto and the Hospital for Sick Children. Cystic fibrosis (CF) is one of the most common fatal genetic diseases in Caucasians. Inherited as an autosomal recessive trait, it affects as many as one in 2,500 live births, a rate from which the carrier frequency can be estimated as approximately one in 25. The disease phenotype is characterized by accumulations of viscid, dehydrated mucus, with consequences most evident in the respiratory, gastrointestinal, and genitourinary tracts, where the clinical features can include chronic obstructive pulmonary disease, pancreatic enzyme deficiency, small-intestinal obstruction, and, in males, infertility. Untreated, the disease usually causes early death from lung infection. Today, improved management often preserves life into adulthood, but the median lifetime remains only 30 years.

5. Non-Insulin-Dependent Diabetes Mellitus: Thrifty Genotype Or Thrifty Phenotype? An examination of current scientific theories regarding the causes of Type II diabetes. http://www.jqjacobs.net/southwest/diabetes.html

Non-Insulin-Dependent Diabetes Mellitus: Thrifty Genotype or Thrifty Phenotype? Diabetes is not one disease, rather there are two major forms, insulin-dependent or type I and non-insulin-dependent or type II. NIDDM as a disease with onset in middle age, in the 10-29 age interval. Children of parents who had NIDDM tend to have small departures from normality in glucose tolerance tests and to be obese. The causes of diabetes are not fully understood. Use of highly refined carbohydrates and sugars has altered dramatically with civilization. How this might influence the development of insulin resistance is a matter of active debate. The fundamental biochemical basis of diabetes is still unknown (Bennett 1999). NIDDM is not just a single entity. There are several forms of late onset, type II diabetes. In the Oji-Cree Native population in Ontario a genetic mutation has recently been associated with a form of NIDDM, maturity-onset diabetes of the young (MODY) (Hegele et al. 1999). This mutation is only known from this single population and only accounts for a portion of their incidence of NIDDM. A genetic mechanism, if one exists, remains to be discovered to explain the vast majority of high prevalences of NIDDM. The rare, inherited subtypes of NIDDM comprise no more than about 10 percent of what is commonly diagnosed as diabetes (Neel 1999).

6. Definition genotype and phenotype the outward physical manifestation of internally coded, inheritable, information. There are two parts to this definition This is the "outward, physical manifestation" of the organism. http://www.brooklyn.cuny.edu/bc/ahp/BioInfo/GP/Definition.html

Genotype and Phenotype Definition ... the outward physical manifestation of internally coded, inheritable, information. There are two parts to this definition ... This is the "outward, physical manifestation" of the organism. These are the physical parts, the sum of the atoms, molecules, macromolecules, cells, structures, metabolism, energy utilization, tissues, organs, reflexes and behaviors; anything that is part of the observable structure, function or behavior of a living organism. This is the "internally coded, inheritable information" carried by all living organisms. This stored information is used as a "blueprint" or set of instructions for building and maintaining a living creature. These instructions are found within almost all cells (the "internal" part), they are written in a coded language (the genetic code), they are copied at the time of cell division or reproduction and are passed from one generation to the next ("inheritable"). These instructions are intimately involved with all aspects of the life of a cell or an organism. They control everything from the formation of protein macromolecules, to the regulation of metabolism and synthesis.

Genotype and Phenotype Flow of Information Before a trait can be observed ... ... biological information must be expressed. DNA molecules store the necessary instructions for building a protein macromolecule. These instructions are copied from the DNA molecule into the form of an RNA molecule. One, or many copies can be made of these instructions. Each of these RNA copies (often called 'messenger RNA' or 'mRNA') move away from the DNA templates and enter the cytoplasm of the cell, where they encounter the machinery that will convert the biological information (the instructions) into the correct linear sequence of amino acids that will become a functioning protein. Once the protein has been correctly assembled and folded it can go to work. In the example of the red-color trait, this protein is in the form of an enzyme catalyst that enhances and speeds up the chemical reaction producing the red pigment. As the protein goes to work the trait is produced. In this example, the trait is the red color seen in the petals of the flower.

9. Genotype---->Phenotype In the flow of information from genotype to phenotype, two steps requirethe copying of nucleotide sequence information into a different form. http://opbs.okstate.edu/~melcher/MG/MGW2/MG2.html

Molecular Genetics Other Pages Expanded Central Dogma of Molecular Biology In the flow of information from genotype to phenotype, two steps require the copying of nucleotide sequence information into a different form. The first step, the copying of the DNA information into RNA, is designated transcription by analogy with medieval monks sitting in their cells copying, letter by letter, old Latin manuscripts. The letters and words in the new version are the same as in the old, but they are written with a different hand and thus have a slightly different appearance. The second step, in which amino acids are polymerized in response to the RNA information, is called translation . Here, monks (a few centuries later) take the Latin words and find English, German or French equivalents. The product is in a different language, in our case in the language of protein sequence. After transcription and before translation the RNA transcripts are processed to produce mature messenger RNA (mRNA). The products of translation

10. Genotype & Phenotype In a narrow genetic sense, the genotype defines the phenotype. Buthow phenotypes. How do we get from genotype to phenotype? Central http://biomed.brown.edu/Courses/BIO48/5.Geno.Pheno.HTML

PHENOTYPE AND GENOTYPE Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related. In a narrow "genetic" sense, the genotype defines the phenotype. But how, in and evolutionary sense, does the phenotype "determine" the genotype? Selection acts on phenotypes because differential reproduction and survivorship depend on phenotype. If the phenotype affecting reproduction or survivorship is genetically based, then selection can winnow out genotypes indirectly by winnowing out phenotypes. How do we get from genotype to phenotype? Central dogma DNA via transcription to RNA via translation to protein ; proteins can act to alter the patterns and timing of gene expression which can lead to cytodifferentiation where cells take on different states; cell communication can lead to pattern formation and morphogenesis and eventually we have an adult!

Next: Operators Up: Representation Previous: Strings Genotype and Phenotype Space In the traditional genetic algorithm genetic operators act on the genotype. That is, they blindly manipulate the string representing the problem. This is not necessary, we can consider operators acting in the phenotype space, i.e. the problem space. For example if we had a problem defined on a lattice then we could consider a crossover operator which divided the lattice into two contiguous pieces and swap the solution in either piece. This would appear simple in the phenotype space but might be very complicated in the genotype space. For many simple test problems it is possible to choose a representation so that genotype space has a similar structure to phenotype space. When this isn't the case then one should consider using phenotype operators. University of Southampton Last modified 30 Oct 2000

19. Genotype And Phenotype genotype and phenotype Jeffrey J. Wine It is interesting to contemplatean entangled bank, clothed with many plants of many kinds http://www-psych.stanford.edu/~wine/206lecture2.html

Genotype and Phenotype Jeffrey J. Wine Charles Darwin, The Origin of Species. The human genome. The human genome consists of ~100,000 genes and ~3,000,000,000 paired nucleotides. Perhaps 95% of the DNA is non-coding, leaving perhaps 150,000,000 nucleotides for the genes, or 1500 nucleotides per gene. After subtracting non-coding regions, the average gene product would be predicted to be less than 500 amino acids in length. The human genome project The origins of the human genome project are usually traced to a 1985 meeting on human genome sequencing held by Robert Sinsheimer at the University of California, Santa Cruz, leading Charles DeLisi and David Smith to develop plans for a Human Genome Initiative sponsored by the Department of Energy. NIH funding for human genome research began in 1987. The same year, DOE recommended a 15-year effort to map and sequence the human genome and designated a set of specialized human genome centers. The U.S. Human Genome Project formally began in October of 1990. In 1991 a genetic linkage map of the entire human genome was published, based on polymerase chain reaction/Sequence-tagged sites (PCR/STS). Spinoffs included attempts to sequence genomes of other organisms. The first sequenced eukaryotic genome.

From Genotype to Phenotype: Linking Bioinformatics and Medical Informatics Ontologies G2P main page G2P participants list G2P Presentations As part of the Manchester Bioinformatics Week there will be a one-day workshop on "From genotype to phenotype: Linking Bioinformatics and Medical Informatics Ontologies". The day-long meeting will be split over Saturday 23rd Sunday 24th March 2002 at the Chancellors Conference Centre at the University of Manchester . The meeting co-charis are Robert Stevens and Alan Rector , of the bioinformatics and Medical Informatics Groups at the Department of Computer Science, University of Manchester. The schedule for this and the other Manchester Bioinformatics Week meetings is available and will be extended closer to the meeting dates. Background The medical informatics community has had an interest and a wealth of experience in developing and using ontologies, that stretches back over many decades. The younger Bioinformatics community has also indicated a growing interest in the subject area. There is both a common interest and a diversity in these fields, that together, we hope can be of mutual interest and benefit to both communities. The linking of genotype and phenotype ontologies offers interesting opportunities for collaboration between Medical Informatics and Bioinformatics. Ontologies should be integral in the storage, management and analysis of data in eScience and eMedicine and it is hoped that this meeting can initiate such collaborations.
