Moreover, it was predicted that MZ and DZ twins are more likely to perceive their sibling
as a main

Tancredy and Fraley (2006)
compared in a sample of 62 twins (30 MZ and 32 DZ) and 928 NT siblings, whether twins and non-twins differed in their use of non-siblings (e.g., mothers, friends)
as attachment figures.
Thus, we predicted that (3) MZ twins are more likely to choose their twin
