Virtual twins are two children who are generally the same age and who are not genetic siblings, yet they are "reared together since infancy".[1] Others have defined virtual twins as "unrelated children born within nine months of each other who enter a family, through birth or adoption, in the first year of life.[2]
This phenomenon has led to the creation of the Fullerton Virtual Twin Study (FVTS) at California State University, Fullerton (CSUF).[3]
