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 …

6 days ago · Epistasis is a circumstance where the expression of one gene is modified (e.g., masked, inhibited or suppressed) by the expression of one or more other genes.

Aug 19, 2025 · Epistasis is the phenomenon where one gene alters the phenotypic expression of another. The gene that masks or modifies an effect is called the epistatic gene, while the gene …

Whether or not they are sorting independently, genes may interact at the level of gene products such that the expression of an allele for one gene masks or modifies the expression of an …

Aug 3, 2023 · Epistasis is the interaction between two non-allelic genes where the phenotypic expression of one gene is masked or suppressed by the expression of one or more other genes.

The term epistasis describes a certain relationship between genes, where an allele of one gene (e.g., ‘spread’) hides or masks the visible output, or phenotype, of another gene (e.g., pattern).

Apr 14, 2023 · Epistasis is a phenomenon in genetics whereby the presence or absence of mutations in one or more extra genes, referred to as modifier genes (genetic modifiers), …

Jul 15, 2025 · Epistasis is a phenomenon in which the effect of a gene mutation is dependent on the presence or absence of a mutation in one or other genes. They are termed as modifier genes.

Epistasis is an inheritance pattern where one gene's product influences the phenotype of another gene. For example, in human blood type, the H protein connects A and B molecules to red …

The definition of epistasis in biology is the genetic phenomenon in which the presence of one gene inhibits the expression of a phenotype encoded in another separate gene.
