A large amount of research has been devoted to the detection and investigation of epistatic interactions. However, there has been much confusion in the literature over deﬁnitions and interpretations of epistasis. In Epistasis can also occur when a dominant allele masks expression at a separate gene.
[ ĕ-pis´tah-sis] 1. suppression of a secretion or excretion, as of blood, menses, or lochia. 2. the interaction between genes at different loci, as a result of which one hereditary character is unexpressed, or is masked by the superimposition of another upon it. See also dominance. adj., adj epistat´ic. In modern usage, epistasis refers to any relationship of nonadditive interaction between two or more genes in their combined effects on a phenotype.
Epistasis can be of the following types. 2021, Hardback. Köp boken Epistasis hos oss!
Definition of Epistasis: Due to the phenomenon of dominance a recessive allele remains obscure in the hybrid. But when two different genes which are not alleles, both affect the same character in such a way that the expression of one masks, inhibits or suppresses the expression of the other gene, it is called epistasis.

evaluated models accounting for additive, dominance, and first-order epistatic epistasis for growth traits as those components are typically not independent.

Expected influence of linkage disequilibrium on genetic variance caused by dominance and epistasis on quantitative traits.
Huvudskillnaden mellan epistasis och pleiotropi är att epistasis är fenomenet där en gen på ett ställe förändrar det fenotypiska uttrycket av. Epistasis is a phenomenon in genetics in which the effect of a gene mutation is dependent on the presence or absence of mutations in one or more other genes, respectively termed modifier genes. In other words, the effect of the mutation is dependent on the genetic background in which it appears. Epistasis is a circumstance where the expression of one gene is affected by the expression of one or more independently inherited genes. For example, if the expression of gene #2 depends on the expression of gene #1, but gene #1 becomes inactive, then the expression of gene #2 will not occur.

A unified model for functional and statistical epistasis and its application in quantitative trait loci analysis. JM Álvarez-Castro, Ö Carlborg. Genetics 176 (2)
Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. 2015-07-27 The epistasis test can either be case-only or case-control. All pairwise combinations of SNPs can be tested: although this may or may not be desirable in statistical terms, it is computationally feasible for moderate datasets using PLINK, e.g.

For example, if the expression of gene #2 depends on the expression of gene #1, but gene #1 becomes inactive, then the expression of gene #2 will not occur. In this example, gene #1 is said to be epistatic to gene
