What Is Epigenetics?
As an organism grows and develops,
carefully orchestrated chemical reactions activate and deactivate parts
of the genome at strategic times and in specific locations. Epigenetics
is the study of these chemical reactions and the factors that influence
them.
Epigenetics and 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. It goes against the idea that inheritance happens only through the DNA code that passes from parent to offspring. It means that a parent's experiences, in the form of epigenetic tags, can be passed down to future generations.
As unconventional as it may be, there is little doubt that epigenetic inheritance is real. In fact, it explains some strange patterns of inheritance geneticists have been puzzling over for decades.
