The genotype phenotype distinction is drawn in genetics . Genotype is an organism s full hereditary information, even if not expressed. Phenotype is an organism s actual observed properties, such as morphology biology morphology , Developmental biology development , or behavior . This distinction is fundamental in the study of biological inheritance inheritance of trait biology trait s and their evolution . The genotype represents its exact genetic makeup the particular set of gene s it possesses. Two organisms whose genes differ at even one locus genetics locus position in their genome are said to have different genotypes. The transmission of genes from parents to offspring is under the control of precise molecular mechanisms.

Random Match Possibility RMP is a kind of measure in population genetics to measure the possibility of a person random ly picked out of the general population and matching the genotype measured exactly. ref cite web url http www.newscientist.com article mg20727743.300 how dna evidence creates victims of chance.html?full true title How DNA evidence creates victims of chance date 18 August 2010 publisher New Scientist ref A genotype has a number of allele s, and each allele has a allele frequency frequency in a certain race. This frequency is the RMP of that allele. To calculate the RMP of a certain genotype, multiply the frequencies of the alleles in the genotype together. This will give the RMP of the genotype. In forensic science , the evidence from the crime scene is gathered and the genotype of DNA evidence is collected. This is then matched with the suspect. The RMP of the evidence is useful in convincing the jury, because the chances of the genotype of the evidence and that of the suspect matching is very low, and therefore it can hardly be claimed that the suspect is innocent, as the chances of it being so is very low.

Unreferenced date February 2008 for the measure of the ideas expressible in a programming language Expressivity computer science Expressivity is a term used in genetics to refer to variations in a phenotype among individuals carrying a particular genotype . The term can be used to characterize qualitatively or quantitatively the extent of phenotypic variation given a particular genotype. The term is analogous to the severity of a condition in clinical medicine . For example, the amount of blood ejected from the pumping heart with each contraction can be quantitated by echocardiography and is called the ejection fraction. If a specific genotype is associated with the development of congestive heart failure, the expressivity would be represented by the range of ejection fractions seen in patients that have that genotype. As a more qualitative example, the blue gene might have an expressivity of 25 for individuals that express the blue gene and appear light blue, and 75 for individuals that express the blue gene and appear dark blue.Expressivity is measured only when there is 100 penetrance. This differs from penetrance , which refers to the likelihood of the gene generating its associated phenotype at all, as determined by the proportion of individuals with a given genotype who also possess the associated phenotype. In contrast, expressivity refers to the influence of an expressed gene at the level of particular individuals. Variable expressivity occurs when a phenotype is expressed to a different degree among individuals with the same genotype. For example, individuals with the same allele for a gene involved in a quantitative trait like body height might have large variance some are taller than others , making prediction of the phenotype from a particular genotype alone difficult. The expression of a phenotype may be modified by the effects of aging, other genetic loci, or environmental factors.

Onesource date April 2009 In genetics , a test cross , first introduced by Gregor Mendel , is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. More simply test crosses determine the genotype of an individual with a dominant phenotype. Test crosses involve breeding the individual in question with another individual that expresses a recessive version of the same trait. If all offspring display the dominant phenotype, the individual in question is homozygous dominant if the offspring display both dominant and recessive phenotypes, then the individual is heterozygous. In some sources, the test cross is defined as being a type of Backcrossing backcross between the recessive homozygote and F1 generation or F1 generation crossed with recessive parent is said to be a Test cross . If the individual being tested produces any recessive offspring except in cases of incomplete penetrance its genotype is heterozygous. If all the offspring are phenotypically dominant, its genotype is homozygous. References reflist refbegin cite book author Hopson, Janet L. John H.

Orphan date November 2006 Refimprove date April 2007 The MN blood group in humans is under the control of a pair of Dominance relationship Co dominance co dominant allele s, L sup M sup and L sup N sup . Most people in the Eskimo population are M M, while this genotype is rare among Indigenous Australians Aborigines . In fact, they tend to possess the opposite genotype N N . The MN blood group system is under the control of an autosomal locus found on chromosome 4 out of 23, with two alleles designated LM and LN. The bloodtype is due to a glycoprotein present on the surface of red blood cells, which behaves as a native antigen . Phenotypic expression at this locus is codominant because an individual may exhibit either one or both antigenic substances. Frequencies of the two alleles vary widely among human populations.

Refimprove date November 2010 Genotyping is the process of determining the genes genotype of an individual by examining the individual s DNA sequence by using bioassay biological assays . More accurately, genotyping is the use of DNA sequences to define biological populations, by use of molecular tools such as restriction fragment length polymorphism identification RFLPI of genomic DNA, random amplified polymorphic detection RAPD of genomic DNA, and amplified fragment length polymorphism detection AFLPD . Genotyping does not necessarily involve defining the genes of an individual. Current methods of genotyping include PCR , DNA sequencing , Allele specific oligonucleotide ASO probes, and Sequencing by hybridization hybridization to DNA microarray s or beads. Genotyping is important in research of genes associated with disease. Due to current technological limitations, almost all genotyping is partial. That is, only a small fraction of an individual s genotype is determined.
