Would novel family relationships generated by cloning prove harmful to family members?
Features distinguishing MZ twin relationships from those of other twins and siblings include higher levels of attachment—specifically, security and proximity.27 Twins (both MZ and DZ) indicated higher levels of intimacy with their co-twins than with their friends, although MZ and DZ twins did not differ in this dimension. MZ twins were, however, more likely than DZ twins to identify their co-twin as their best friend.28 Another study found that the quality of DZ twin relationships depended on frequency of contact, while this effect was minimal or absent in MZ twinships.29The foregoing suggests potential psychological benefits associated with HRC. Perhaps empathy and understanding between cloned children and their parents would be heightened. Would parental expectations of behavioral similarity in genetically identical offspring be psychologically damaging to these children? Ordinary parents entertain a range of expectations for their children. Donor parents, like ordinary parents, woul
