It is often thought that a pair of identical twins raised together may be more different than a pair raised apart. The problem is that there have only been about 100 pairs of twins like these that have ever been studied. This creates a fairly small amount of data to study. There is a reason that the twins may be more similar if they are raised separately. It is thought that twins raised together may “divide up the territory” and also...
