If you were adopted, you have at least 3 parents - and possibly many more! Epigentics teaches us that parenthood is laregly driven by epigenetics not just DNA (I share 60% of my DNA with a banana but little or no epigenetics)
So if you were adopted, see ALL of the parents as just that - Parents
Epigenetics covers the signals and proteins that every cell, and structure receives. The signals and proteins dictate how the cell develops and changes.
Many adopted children feel they need to choose - they do not!
