Are identical twins 100% the same?
The DNA of monozygotic twins tends not to be 100% identical, and epigenetic and environmental differences further widen the gap between twin pairs. It’s not nature or nurture; it’s a complex interaction between our genes, our environment, and our epigenetic markers that shape who we are and what illnesses befall us.
