Epistasis in Epistasis is a term used in the field of genetics and is defined as an occurrence where one gene or more somehow changes or “masks” the expression of another gene. In these cases, the gene whose traits are not expressed is called a “hypostatic” gene, while the other genes whose traits have surfaced are called “epistatic” genes.

A gene is said to be epistatic when its presence suppresses the effect of a gene at another locus. Epistasis (which means “standing upon”) occurs when the phenotype of one locus masks, or prevents, the phenotype of another locus. Thus, following a dihybrid cross fewer than the typical … 6.2: Epistasis and Other Gene Interactions - Biology LibreTexts Dominant Epistasis [12 : 3 : 1 Ratio]: When a dominant allele at one locus can mask the expression of both alleles (dominant and recessive) at another locus, it is known as dominant epistasis. In other words, the expression of one dominant or recessive allele is masked by another dominant gene.

Epistasis should not be confused with dominance, which refers to the interaction of genes at the same locus. Principles of Biology Brindle color: partial dominance and epistasis Brindle coloration is a black and brown striping pattern that is caused by different alleles at the “K locus”, which is probably a gene called ASIP that controls pigment switching (Figure 1; Ciampolini, 2013).
Epistasis can generate a short-term advantage for recombination when it fluctuates over time, with different allele combinations being favored during different time intervals (Maynard Smith, 1971; Charlesworth, 1976; Barton, 1995). 2004-07-26 · Biology Glossary search by EverythingBio.com The masking of the phenotypic effect of alleles at one gene by alleles of another gene.

Epistasis can also occur when a dominant allele masks expression at a separate gene. Fruit color in summer squash is expressed in this way. Homozygous recessive expression of the W gene (ww) coupled with homozygous dominant or heterozygous expression of the Y gene (YY or Yy) generates yellow fruit, and the wwyy genotype produces green fruit.
