Detailed explanation-1: -Epigenetic modifications can be maintained from cell to cell as cells divide and, in some cases, can be inherited through the generations.

Detailed explanation-2: -Experiences Are Passed to Daughter Cells As cells grow and divide, cellular machinery faithfully copies epigenetic tags along with the DNA. This is especially important during embryonic development, as past experiences inform future choices.

Detailed explanation-3: -Epigenetic marks can pass from parent to offspring in a way that completely bypasses egg or sperm, thus avoiding the epigenetic purging that happens during early development. Most of us were taught that our traits are hard-coded in the DNA that passes from parent to offspring.

Detailed explanation-4: -Recent evidence has indicated that certain epigenetic marks can be inherited, and reshape developmental and cellular features over generations. This review examines the challenging possibility that epigenetic changes induced by environmental factors can contribute to some of the inheritance of disease and disease risk.

Detailed explanation-5: -The fact that epigenetic markers survive through cell division and, in some cases, are passed down to offspring throws a serious wrinkle in our understanding of how traits are inherited.
