  1. Epistasis - Wikipedia

    [1] 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. …

  2. What Is Epistasis? Definition and an Example - Biology Insights

    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 …

  3. Epistasis - National Human Genome Research Institute

    1 day 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.

  4. Epistasis- Definition, Classes, Types, Examples, Significances

    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.

  5. Epistasis | Biology for Majors I - Lumen Learning

    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 allele for a …

  6. Epistasis - University of Utah

    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).

  7. Epistasis - Definition and Examples - Biology Online Dictionary

    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), affects the outcome of a …

  8. Epistasis and Its Effects on Phenotype | Learn Science at Scitable - Nature

    Epistasis describes how gene interactions can affect phenotypes. Did you know that genes can mask each other's presence or combine to produce an entirely new trait?

  9. Epistasis Explained: Definition, Examples, Practice & Video Lessons

    Epistasis is a genetic phenomenon where the expression of one gene influences the phenotype associated with another gene. This interaction can significantly affect traits, such as human blood types.

  10. Epistasis | Definition, Types & Examples - Lesson | Study.com

    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.
