DNA that is associated with histone proteins accumulate to form chromatin because the cells can be affected by genes that are transcribed, inheritable states give rise to epigenetic marks. Epigenetic marks are passed from one generation to the next, despite the fact that all epigenetic marks are deleted during” epigenetic programming”. Some characteristics or diseases are passed from the grandparent to parents to the children. I believe that epigenetic are inheritable, they are transferred in a process called transgression. The decision made by the parents can affect the characteristics of the kid, for instance, history of famine result in the health effects of the grandson of persons who had restricted diet.
Methylation can escape the reprogramming process. Therefore, it can be passed from the parents to the offspring; this reveals how epigenetic occur. The reason behind inheritance
...is that methylation accumulates at the genes for entire life in response to the environmental factors, such as nutrition or chemical exposure, if the genes are affected, and are passed to the offspring, their genes are also damaged. Also, gene retains memories of the experience, therefore, the characteristics of the parents or the grandparents are inherited by the children. Some of the environmental factors such as malnutrition associated with poverty are partially inherited. But one thing we should note here is that we can only inherit certain problematic features from the parents and then our life experience changes those conditions to better. (Abhay, 2015)
Nature of the information carried by epigenetic marks store includes, they are affected by environmental factors, and the marks cannot be erased during the epigenetic process. The information is transmitted in histone in the DNA; tha
genetics can be inherited up to the second generation.
