上位性（epistasis）原来的含义是指某一基因受不同位点上别的基因抑制而不能表达的现象。现在上位性的涵义已有了扩展，在群体遗传学和数量遗传学中非等位基因的遗传效应为非相加性 …

Epistatic mutations therefore have different effects on their own than when they occur together. Originally, the term epistasis specifically meant that the effect of a gene variant is masked by …

2019年5月8日 · epistatic与interaction之间的区别与联系？ genetic上的interaction是如何定义的？ Epistasis is the phenomenon where the effect of one gene (locus) is dependent on the …

上位基因（epistatic gene）指的是一对等位基因受到另一对等位基因的制约，并随着后者不同前者的表型有所差异。这一现象称为上位效应(epistasis)。起遮盖作用的基因如果是显性基因，称 …

2016年11月22日 · Epistasis is the interaction between genes that influences a phenotype. Genes can either mask each other so that one is considered “dominant” or they can combine to …

Epistasis is an interaction at the phenotypic level of organization. The genes that are involved in a specific epistatic interaction may still show independent assortment at the genotypic level.

Epistasis is fundamental to the structure and function of genetic pathways and to the evolutionary dynamics of complex genetic systems. High-throughput functional genomics, systems-level ...

2023年4月14日 · Epistasis is when one gene conceals the phenotypic expression of another gene as a result of the interaction of nonallelic genes at two or more loci.

Epistatic gene-gene interactions are perhaps more common than we think. Indeed, some scientists believe that epistasis is ubiquitous in biology and has been ignored for too long in …

3 天之前 · Epistasis is a circumstance where the expression of one gene is affected by the expression of one or more independently inherited genes.
