Definition of epistasis in English:

epistasis

noun ɪˈpɪstəsɪsəˈpistəsəs

mass nounGenetics

The interaction of genes that are not alleles, in particular the suppression of the effect of one such gene by another.
〔遗传〕上位性，异位显性
Example sentencesExamples
- For geneticists, epistasis is associated with the limits of the additive model of gene action.
- This advantage of sex should be especially substantial when mutations interact through negative epistasis.
- These results suggest that future genetic models for the evolution of aging should incorporate the effects of epistasis.
- Genetic epistasis of gene expression can also be considered with large sample sizes.
- Neither earlier study was able to demonstrate a significant effect of epistasis, either positive or negative.

Derivatives

epistatic

adjective ˌɛpɪˈstatɪk

Genetics

Thus, neither allele is epistatic to the other in permitting the occurrence of expansions or contractions.
Example sentencesExamples
- It is known that epistatic selection may produce significant linkage disequilibrium in natural populations.
- Such sites may be indicative of hotspots of recombination or mutation or epistatic selection.
- The results suggested that a minimum of two genes with epistatic effects were involved in the genetic control of cleistogamy.
- This study shows that most hybrid incompatibilities are recessive and epistatic.

Origin

Early 19th century: from Greek, literally 'stoppage', from ephistanai 'to stop'.
