WebEpigenetics & Inheritance. We used to think that a new embryo's epigenome was completely erased and rebuilt from scratch. But this isn't completely true. Some epigenetic tags remain in place as genetic information passes from generation to generation, a process called epigenetic inheritance. Epigenetic inheritance is an unconventional finding. Web5. Epigenetic adaptation in inbred and clonal species. Experimental studies on plants provide some of the best-known examples of epigenetic variants that are inherited across multiple generations . However, it is still unclear to what extent transgenerational epigenetic inheritance occurs in plants in nature.
