Exploring Familial Resemblance in Romantic Attachment : Shared Genes and Shared Rearing Environment Do Not Equal Shared Attachment

Abstract

We conducted a series of studies to explore the possibility that romantic attachment style is transmitted via the family, either through shared genes or shared rearing environment. Family members should be similar in attachment style if it is transmitted familially. To test this idea, we obtained romantic attachment scores from various within-family pairings.
