Information AboutGenotype |
|
Typically, one refers to an individual's genotype with regard to a particular Gene of interest and, in Polyploid individuals, it refers to what combination of Allele s the individual carries (see Homozygous , Heterozygous ). Any given gene will usually cause an observable change in an organism, known as the phenotype. The terms genotype and phenotype are distinct for at least two reasons: #To distinguish the source of an observer's knowledge (one can know about genotype by observing DNA; one can know about phenotype by observing outward appearance of an organism). #Genotype and phenotype are not always directly correlated. Some genes only express a given phenotype in certain environmental conditions. Conversely, some phenotypes could be the result of multiple genotypes. With careful Experimental Design , researchers can use statistical methods to Correlate differences in the genotypes of populations with differences in their observed Phenotype . These Association Studies can be used to determine the genetic Risk Factor s associated with a Disease . They may even be able to differentiate between populations who may or may not respond favorably to a particular Drug treatment. Such an approach is known as Personalized Medicine . Inspired by the Biological concept and usefulness of genotypes, Computer Science employs simulated genotypes in Genetic Programming and Evolutionary Algorithm s. Such techniques can help Evolve Mathematical solutions to certain types of otherwise difficult problems. |
