epigenetics cannot alter your DNA, just the way it is activated and transcribed. And that can be heritable, but it usually isn't as straight forward as just getting it from your parent.

Example: They fuck up the mother's lungs with smoke and that changes frequency that a histone protein is modified or a transcription factor binds to a DNA sequence. These epigenetic features eventually lead the mom to have fucked up lungs. The mother can pass on these epigenetic features to her kids, which will eventually have fucked up lungs as well because of their DNA not being transcribed correctly. But they won't be BORN with fucked up lungs, they will just develop them over time due to the heritability of gene expression from their mother.

The only way they could maybe fuck up their lungs on birth is if they fucked up the mothers lungs while she was pregnant, and that changed the way that her still developing babies are regulated.
