heritable "on/off switches" for gene sequences due to environmental factors.

Explanation: Epigenetic changes (e.g., DNA methylation, histone modifications) alter gene expression without changing the DNA sequence and can be inherited through cell divisions and sometimes across generations, often in response to environmental cues.
