Twins. Similarities, differences and individuality

This study aims to investigate the self-differentiating perceptions and the separation-individuation’s process in emerging adulthood twins.

The data show that there are no difference between not bisexual MZ and DZ couple. Moreover, there is a less strong reciprocal relation in the sex opposite DZ couple than in the others
