Do couples really grow to look alike through gene integration? I remember when we were studying Genetic Engineering in school. The teacher, probably trying to make the lesson easier to grasp, told us: don’t assume gene integration can only happen in a sophisticated laboratory. Your own body is, in fact, the most exquisite genetic engineering lab there is—it can not only create new life, but also make two people who share no blood relation grow to look more and more alike. By the time we graduated, no one had been able to refute the teacher’s point, because many couples really do come to resemble each other more and more. Everyone seemed simply to accept what the teacher said.
