Epigenetic inheritance is the pattern in heredity in which the changes are introduced either into the nuclear gene or the chromosome. These modifications tend to alter the expression of genes. The effects of these modifications are temporary but can be passed down to the next generation if the changes have occurred in the germ cells i.e. sperm and egg cells.
Sometimes, the alterations that have occurred in the genetic material of the germ cells get erased due to the process of reprogramming. As a result of this, the fetus’ cells start making their own epigenetic changes.
