您要查找的是不是：
- Epigenetic changes are heritable changes to the regulation of a cell's genes, caused by extra molecules being attached to those genes. 即便最近对代际遗传现象的观察也显示：这一现象初看起来像是获得性遗传（这是达尔文派的一个禁忌），但可能并非如此。
- Epigenetic phenomena, heritable changes in phenotype, and hence in gene regulation, but not in DNA sequence, occur in the process of polyploidization in many plants. 表观遗传现象是指基因表达发生改变但不涉及DNA序列的变化, 它存在于许多植物的多倍体化过程中，而且能够在代与代之间传递。
- Epigenetics refers to the heritable changes in gene expression without any alteration in DNA sequence, including DNA methylation, histone modification and chromatin conformation. 摘要表观遗传学是指基于非基因序列改变所致基因表达水平的变化，如DNA甲基化和组蛋白修饰等；
- Epigenetic effects,which were defined clearly in recent years,are most often used to denote all those somatically heritable changes in gene expression that do not involve changes in DNA sequence. 后生效应是近几年才定义清楚的一类现象，指所有那些DNA序列没有改变的基因表达后体细胞的遗传表型发生改变的现象。
- We may track heritable changes across genotypes and morphology (physical form), as well as across life history traits such as virulence, transmissibility, host specificity and reproductive rate. 我们可以在基因型与形态（体型）之间，以及在各个阶段的生命史特徵，像是毒性、传染力、宿主专一性与生殖率等之间，追踪遗传变化；
