The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next.

表观基因组可以被环境改变，这些改变从一代蠕虫传递到下一代。

These are considered epigenetic changes, meaning that they effect which genes are expressed without directly changing the genetic code.

这些被认为表观遗传变异，就说它们在不直接更改基因代码的前提下，影响了哪些基因被表现出来。
