thumb|163x163px|Paramutation was first observed by the effect it had on the color of corn kernels in maize plants In epigenetics, a paramutation is an interaction between two alleles at a single locus, whereby one allele induces a heritable change in the other allele. The change may be in the pattern of DNA methylation or histone modifications. The allele inducing the change is said to be paramutagenic, while the allele that has been epigenetically altered is termed paramutable. A paramutable allele may have altered levels of gene expression, which may continue in offspring which inherit that

在表观遗传学中，副突变（paramutation）又称類突變，是单个基因座上两个等位基因之间的相互作用，其中一个等位基因诱导另一个等位基因发生可遗传变化；此为一種打破常規的遺傳模式。這種情況首先在玉米中發現，隨後在其他植物、真菌、甚至小鼠中發現。而，用玉米所做的研究指出副突變是由RNA引導的。
