Summary
Despite their shared genetic makeup, some "identical" twins don't appear identical at all-raising important questions about the role of environment in human development. This program explores several ways in which monozygotic twins grow and change on separate paths as well as the epigenetic, anatomical, and psychological factors involved. With the help of 4D scanning and CGI graphics, viewers learn how uterine conditions impact identical twins differently and how life experiences can shape gene expression. Case studies include gay and straight twin brothers, obese and slender twin sisters, and another pair of sisters who seem to have aged at dramatically different speeds. Meanwhile, twin doctors reflect on their contrasts as well as their similarities. A
