2 Aug 2014 those loci controlling quantitatively measurable traits Pleiotropy describes situations where one gene affects multiple traits Epistatic Gene 

The key difference between epistasis and pleiotropy is that epistasis is the phenomenon in which one gene at one locus alters the phenotypic expression of a gene at another locus while pleiotropy explains the phenomenon in which a single gene affects multiple phenotypic traits. Epistasis and pleiotropy are two phenomena in genetics.

Epistasis, or gene–gene interaction, has also been treated as an exception to the Mendelian one gene–one phenotype paradigm. Pleiotropy. Pleiotropy being supposedly more often deleterious, it has been proposed that coding changes may be selected against more than cis-regulatory change, thus predicting a prevalence of cis-regulatory changes in evolution (Carroll, 2005; Stern, 2000). The factors that influence genetic architecture shape the structure of the fitness landscape, and therefore play a large role in the evolutionary dynamics. Here the NK model is used to investigate how epistasis and pleiotropy -- key components of genetic architecture -- affect the structure of the fitness landscape, and how they affect the ability of evolving populations to adapt despite the Many examples of pleiotropy have been identified in various species, including humans. In fact, pleiotropic Citation: Lobo, I. (2008) Pleiotropy: One Gene Can Affect Multiple Traits.

The gene that suppresses is said to be epistatic, and the gene which remains obscure is hypostatic.

Pleiotropy, in which one mutation causes multiple phenotypes, has traditionally been seen as a deviation from the conventional observation in which one gene affects one phenotype. Epistasis, or gene–gene interaction, has also been treated as an exception to the Mendelian one gene–one phenotype paradigm.

It then outlines the essential approaches to finding single genes associated with specific behavioral- and welfare-related  They find that there is less genetic correlation with linkage than with pleiotropy, unless the mutation rate is high, which leads to a discussion about  The alleles at a locus share a distribution of mutation effects, that can be either two-dimensional (with pleiotropy) or one-dimensional.

Polygenic  Epistasis is the masking of the phenotype of one mutant by the phenotype of a of interest affect a switch regulation versus a substrate dependent pathway,  Epistasis is a circumstance where the expression of one gene is affected by the expression of one or more independently inherited genes. 17 Sep 2012 Bjørn also blogs at Pleiotropy. What is epistasis? Epistasis is a measure of the strength of epistatic interactions.
